  1. Entering into vaping from smoking, smokeless tobacco, hookah, or not as a previous tobacco user can be a bit overwhelming, especially the market and devices now currently available. When I started the market was very limited compared to now, though I entered just slightly before the advent of cost affordable variable wattage hit the market, Variable Voltage (VV) was readily available, and only a couple Variable Wattage/Variable Power (VW) devices were on the market (namely the Evolv Darwin). There are all types of device genres out there, and constantly evolving from the generations of devices before them, I remember cig-a-likes were the only thing on the market affordable, home made mechanical designs diagrams for the DIY minded, up to the Ego Class, to mods, to today what we have currently available, this isn't that type of walk in the past, this is a help blog for those that know how to use a search form in a website forum, yet the principles behind Variable devices are the same, and "YOU" as the "End User" have to do the experimenting. Vaping is distinct and unique to the end user, though many may fall into the same juices, devices, juices, PG/VG ratios, coil types, the list of variables is long and like playing a Pachinko machine when conversing with a person from behind a computer screen, so I'll give some basics that come to play.

    Standard Output non-variable device = this device will output depending on its model 3.2 to 3.3 volts (basic cig-a-like device) to 3.7nominal volts (Ego Pen Device Class) to 4.2 volts decreasing as charge of a battery decreases (Mechanical Mod), the only way to affect the output of these devices is to change the resistance or your atomizer, lower Ohm coil = higher wattage, higher ohm coil = lower wattage, basically a pedal bicycle in analogy
    Variable Voltage = this type of device can contain a Buck Circuit (allows to lower voltage below the current charge level of the battery), a Boost Circuit (allows to draw more amps from the battery to convert to voltage and boost it onto the current charge level of the battery, thus go higher than what the battery can output), these are also affected by Ohm's of the coil, higher or lower voltage will increase or lower ending wattage at the coil itself, basically this is a stock, entry level Chevy Sub-Compact car with just a manual transmission, meaning you have to do all your calculations yourself and adjust everything manually, Ego Twist Pen Devices, the Original Innokin iTaste MVP Version 1, Original Vamo, and the higher end Original Provapes Provari, Provari 2, Provari Mini, and Provari 2.5.
    Variable Wattage = variable wattage or variable power (both apply to this) are very, very, very similar to variable voltage as a variable wattage device adjusts voltage to reach a set wattage setting. A simple formula to figure wattage is Voltage X Voltage/Resistance=Watts (Power). A VW device reads the resistance of your coil, then basically does the formula in reverse knowing what watts you have set and the Ohm reading of the coil, ie 12watts X Resistance=Needed Voltage to reach set wattage. Variable Wattage is basically in analogy the above mentioned Chevy Sub-Compact upgraded with an automatic transmission and cruise control module, it does all the calculations and adjusts itself to what the user sets for wattage.
    Temperature Control = this again is another evolution from variable wattage, or additional module to a variable wattage control chip, set your wattage, set your temperature cap, and the mod adjusts on the fly, spiking initial ramp up at full set wattage, reaches temperature cap, starts throttling and ramping itself up (pulse width modulates) the voltage to maintain the temperature cap. It does this by reading the resistance of the coil hundreds of times a minute, as the coil heats, resistance increases, reach a certain resistance, the chip can logically guess the temperature of the wire with a margin of error plus or minus (+/-), not accurate but close. This requires exotic metal coil wires that the variables of this resistance vs temperature algorithm can be closely guessed, namely Pure Nickel (very low resistance wire and very soft) to Titanium Grade 1 (T1) (semi low resistance a much harder wire) to Stainless Steel Wire (low resistance metal that is also very hard), they are just now getting close to making TC viable with the use of NiChrome (NickelChromium) and Kanthal A1 (an alloy wire with very high resistance, space heaters and other heating elements have used this alloy for years, and so have e-cigs). The benefits of TC is it, if set right, can prevent the formation of formaldahydes, diacetyl (pop corn lung causing agent), AP (another pop corn lung causing agent), and the biggest factor everyone talks about like it is the most important but only a side effect, can help prevent the burning of your wicking, scorching of wickings such as silica and ekowool causes formaldihyde to form, scorched cotton and such other wicking material that sharp, painful scorched feeling on a dry hit, that is formaldihyde in the vapor aerosol you are feeling.

    Okay, now that we have a basic understanding of the basics, here is the gist that you the end user must wrap your mind around. Many atomizer attachments, namely these newer generation sub-ohm clouding tanks (sub-ohm is any resistance below a full ohm) which are high output, great flavored devices that produce large clouds due to heat and inhale technique (straight to lung compared to mouth to lung inhale (what most cigarette, pipe, and hookah users are used to), produce this. It is all in the wattage and heat these devices create that cause this, but even a basic Ego Twist with a Mini Protank 3 going to follow the same principle. "What Wattage, Voltage, Temperature do I set?" Though a coil head may have printed on its side the optimal wattage settings it can sustain, taste of the end user is still subjective to that end user.

    Set your battery device to its lowest setting with a fresh, primed coil in your atomizer, now we take baby steps learning to walk. Juices, coil resistance, nicotine level, PG/VG ratio, airflow, voltage/wattage/temperature all play big factors affecting the next. With a fresh coil, just like a fresh motor in a car, you need to break it in to get to optimal performance so we do not damage it off the starting line, lowest power setting and every few minutes step it up a notch or two (dial potentiometer reostat ego twist class vv device) a couple voltage, wattage or temperature notches (digital screen with push button devices) breaks the coil in gradually. After about a half hour the coil can generally be ramped up higher once the cooling system (the airflow in tandem with the wicking speed, liquid evaporating and being hit by cooler air disipates heat quickly) thus a key element the wicking is wicking at its fastest by this time (the thermostat in the engine has been fully opened up allowing free flow of the liquid in the cooling system to move unrestricted as much as possible). Now depending on VG content, higher power makes these vape better, higher nicotine lower output works best here, different juice flavors have there own sweet spot, so thus we have to experiment "Ourselves" of what settings works best for our current juice, nicotine level, VG percentage, and juice flavor, there no one all catch all Silver Bullet Setting, because every individual is different in their tastes, these settings are unique again to the end user. Step up gradually, start to get a harsh hit (scratchy hit) or get an almost dry hit, back it back down a couple notches, that is the sweet spot, it is not about oh, running a Evic VTC Mini /w Ego One Mega kit with the Titanium Coil, yeah dude I use 430F, max wattage, max airflow, you'll be good dude, or you are on a Sigelei 150watt with a TFV4 with the Quad Coil, take it max to 150 dude you'll be set, or Nautilus Mini with the 1.8ohm head on an iStick30watt, 20watts dude, you'll be good, doesn't work like that.

    Examples.

    My Kayfun V4 and Russian 91% Rebuildable Tanks - restricted airflow, I use higher 12mg 50/50 and 60VG/40PG liquids in them, generally unflavored or tobacco juices, on a Nickel TC 0.2ohm coil, I run them at 15watts max output at a temp of 380F (unflavored) to 450F (tobaccos with rich, very bold, or very sweet tones, bland tobaccos about 400 to 420F), on my SVD 2.0 or Provari Mini 2.5 with a 1.5 to 1.8ohm Kanthal A1 or NiChrome 80 coil, between 8 to 12watts (SVD 2.0) or 3.3 to 3.6volts (Provari)
    My Subtank Plus Tanks (sub-ohm tank), OBS Crius or Griffin Sub-ohm RTA tanks - medium airflow tanks capable of sub-ohm ranging in 0.2 to 0.4ohm range (Nickel or Titanium) coils, 30 to 40watts set at 450F to 500F TC, or with Nichrome 80 coils in the 0.4 to 0.7ohms range 30 to 70watts, using a 6mg nic juice, 70VG/30PG to 80VG/20PG
    My Rebuildable Dripping Atomizers (RDAs, generally reduced chamber flavor atomizers like the Quasar and Derringer RDA) - Generally use Nichrome 80 24awg on a 2.5 or 3.0 mm diameter ohming in around 0.3 to 0.6ohms, about in the 50 to 75watts range, using a 3mg juice, 80VG/20PG to max VG.

    So as you can see, me as a single end user I am all over the board, I vape various liquids depending on my device, mood, flavor (generally unflavored, tobaccos, fuits, candies, and coffee flavors, rarely savory deserts, bakeries, creams, custards, or yogurt flavors), various nicotine levels, and narrow down my atomizers I am still pretty much zig and zag on my voltage, wattage, temperature settings, yet I have been doing this long enough I've learned what to guess at to where I will be when I begin vaping.
  2. This is a blog post with basic information about different box mod types being released and a basics of battery circuits. First though, I will stress if you are using a Mechanical mod of any sort or a 100watt plus regulated mod of any type to invest in 30amp Continuous Discharge Rate batteries for these devices for safety. This is general information I am entering into one post so I am not always having to retype them over and over, instead just link to them. Pre-warning, I am not a definitive expert on battery safety, or any other field, just this is information I have gathered and picked up from posts here on ECF, my own searches and research, shaded a bit with my own opinion and level of comfort with how safe I wish to be, which is a bit conservative toward more safety than caution to the wind.

    Most box mods on the market currently, Mechanical and Regulated are coming in Single battery config, dual battery series, or dual battery parallel configuration, there are a couple triple battery mods coming out that I am glancing and researching over only mildly, but they will follow these three basic circuits, single, series, or parallel. Remember as batteries age from charging and discharging, they lose Milliamp Hours and C Rating, both of these figures determine maximum CDR the battery can handle, either one lowers, the Max CDR decreases as well, and many suggest, including myself, never ask a battery to supply more than 50% to 75% of its max CDR all the time, for 6 even 18months down the road that battery that was 20amp CDR could only produce 10amps CDR, 30amp CDR could be max 15amps at this age. You'll notice the battery is aged due to it will not hold a charge as long as it used to, this represents physical output of the Mah rating, and the battery will get warmer under heavy load than it used to when brand new, so keep this in mind.

    Remember with multi-battery devices, batteries for them should be bought together, marked as a set, charged, and used together, or married together, this makes sure the batteries have the same wear and tear, are balanced, and equal at all times for safety, that way one battery does not under perform the other and put excessive stress on either, ever stress a battery bad things happen, doesn't matter if it is a pairing of 2 batteries, a triple pairing, or even quadruple pairing, keep the batteries equal.

    ***Keeping basic Logs of batteries helps here, date bought, brand and model, CDR of them, Mah Rating of each, label number to keep track of them, even date of first charge after buying, as well as if stored for future use, date of last charge and charge state they were stored in helps, when storing batteries, store them between 3.4 to 3.6volts, periodically check batteries with a volt meter at a full charge, this helps show their age as well, 4.2v charge should be 4.2, not 4.0***

    Single battery - This is pretty simple, we have been running these for a very, very long time. In a mechanical the battery gives output of what it still has in charge at that moment, where most regulated variable voltage or wattage devices can throttle this output higher or lower that charge level. 2 principles of this configuration are the most basic, on a mechanical you use an Ohm's Law calculator or formula to determine your final output using 4.2volts (fresh charge) and your coil resistance (Ohm's) to determine your Amperage and Wattage output, ie a 0.5ohm Dual coil dripper, using 4.2v in a calculator along with 0.5ohms we get 8.4amps and 35.28watts output to understand how safe our CDR drain will be on our battery, or using a 0.25ohm dual coil, we get 16.8amps and 70.56watts output a single battery must be able to provide to us. On a regulated, basic Variable Wattage Device, this calculation is different, though it is still an Ohm's law formula, most mod with regulation will not fire from a battery below a charge level of 3.2volts to 3.6volts, so we use this low battery charge level figure, and divide that into what wattage we have set, example 50watts max output mod, 50/3.2v=15.625amps will be required to be supplied by our battery at that time.

    Multi-Battery Series Configuration - Many of the higher output devices use this configuration, older days it was called stacking batteries, see above about pairing batteries, always use same model pairings together, never mix and match. In a series, or stacked configuration, this is the same thing happening as is used in say a large Maglight Flashlight. In a series, the voltage is doubled from what a single battery is capable of, yet Mah and CDR Amp rating stay the same as a single battery, dual battery, that becomes 8.4volts, same CDR and Same Mah rating of the single cells, Sony VTC4 for instance, 4.2volts fresh charge, 20amp CDR, 2100mah, 2 in a series would be 8.4volts, 20amp CDR, 2100mah, triple series, 12.6volts, 20amp CDR, 2100mah, etc. In a mech we use this high full charge voltage and our coil resistance to determine our Amps and Watts just like a single battery config, regulated series mod like the Sigelei 150watt, we use 150watts/6.4volts=amps (3.2volt low state X2), very few mechs use this config, but many of the regulateds are using this method.

    Multi-Battery Parallel Configuration - Parallel Multi-battery Configurations you see mostly with mechanicals coming out right now, the Eleaf iStick100watt Regulated also uses this method. In a parallel configuration we only get the voltage of a single battery, fresh charge 4.2volts unlike the Series method, but in this configuration load is distributed equally, so our max CDR and Mah are doubled. Using the Sony VTC4 again, these figures would be 4.2volts, 4200mah, and 40amps CDR available. Determining max CDR is the same as a single battery configuration, 4.2v and our coil resistance to determine max CDR and wattage on a mechanical, for a regulated 3.2volts divided into our mods max wattage setting.

    Stay safe out there.

  3. I repeat this information enough, I am posting it into a blog to link to as response when needed or for anyone to reference and link to. All of this is just a reiteration of what others have posted in the past as well as I myself, I am not an expert with any degrees of any sort, nor a major background in electricity or electronics of any sort, just my experience since beginning to vape in 2012, though I do have some background with RC controlled vehicles we use a lot of information and equipment as batteries they also use so there is another avenue of searching for this information as well. Using this blog as well as others being linked to should reduce your risk and increase your safety if you use the information wisely and responsibly. With that said, I will first link to the blogs of 2 members many long time members consider resident experts as follows

    First blog is by @Baditude
    Baditude's blog | E-Cigarette Forum
    This blog has a lot of information to look through with a lot of safety and basics, including "Ohm's Law" and detailed information regarding battery safety, it is all well worth reading as a starter point for a beginner up to the advanced vaper.

    Second blog is by @Mooch
    Mooch's blog | E-Cigarette Forum
    What Mooch brings to the table is quite a few expert years of testing batteries for various businesses and some government projects, he mainly tests the batteries for max temperature thresholds, many know that heat is the enemy for a Lithium based battery, get a battery to hot, bad things happen, using a battery towards its max current output makes batteries get hot, damaging them and lowering their output and life cycle, his lists of tests can help you find the right battery for your application.

    I will stress and voice what most say, there are no batteries made by the direct source manufacturers produce that are over 30amp Continuous Discharge Rating (CDR) on the market, the big 4 that produce batteries we use are Panasonic (mainly lower end), Sony, LG, and Samsung, the only re-wrap name on the market I personally trust is AW (AW IMR) which buy A Bin batteries from manufacturers like Panasonic, Sony, LG, and Samsung, going through a second quality control method, then labelled and sold. Efest, Sub-ohm Cell, AWT, MXJO, IMRen, Basen, Eizfan, Vamped, Vappower are all re-wrap resellers that buy B and C Bin discards, re-wrap these cells, print the battery short pulse rating on the label as their CDR and charge double what the authentic is worth. Unless you know what you are getting, stay away from these brands as best you can, never know if under the wrapper is a Panasonic NCR18650B (6amp CDR, 12amp PDR) or an LG HE2 (20amp CDR, 35 to 40amp PDR) under that pretty bling bling wrapper, never trust a battery at its Pulse Rated Discharge. PDR is a dangerous rating to use, you don't know if that Pulse is 500milli-seconds or 30 Seconds, best to use the Continuous Discharge Rate (CDR) for all your calculations, this is the output the battery can hold and maintain most times the entire charge of the battery. This puts inexperienced vapers at risk with a false sense of safety, "Yeah man, battery says on the label it good up to 35amps, I'm at 32amps, good to go bro...", so not true in all honesty, you are out on a limb, the very furthest and narrow part of a brittle limb, one mishap its game over, that battery will vent on you and unpleasant things will happen. The best tool in a vaper's arsenal is above their shoulders, second best tool in our arsenal is the computer you now sit at reading this, Google, Yahoo, DuckDuckgo, ECF, and several Youtube reviewers that stress safety and being safe, are your best friends and best sources of information.

    All that being said, here is another thing to take into consideration, buying from reputable, authorized re-sellers is also another safety mechanism you have to consider, Amazon, Ebay, several others are good for finding a decent deal on some hardware, a lot of wick and wire, but batteries, *cringes*, no, just don't do it, price of an Efest Purple 35amp battery, a lot of times at Illumination Supply you can find a pair of Sony VTC4's that come in a battery case for the same price as the pretty looking Efest.

    With all that, I will say I will try to keep these below lists up to date as best I can.

    Mech Mods (This includes single battery and dual battery box mods)
    ****In My Opinion, you are running a mech, you need a 30amp CDR battery at all times****
    ****Using Ohm's Law Forumla 4.2v/Resistance (ohms)=Amps , 30amp CDR battery single lowest safe resistance 0.28ohm (50% of max CDR of 15amps) maximum lowest resistance 0.14ohms (that's full 30amps). 25amp CDR single battery lowest safe resistance 0.34ohms (that's 12.5amps 50% of the total CDR) maximum lowest resistance 0.17ohm (that's full 25amps). 20amp CDR battery single lowest safe resistance 0.42ohms (that's 10amps 50% of the total CDR) maximum lowest resistance 0.21ohms (that's full 20amps). Parallel Dual Battery safest resistance with 30amp batteries is 0.14ohms (that's 30amps, 15amps per battery) maximum lowest that is advisable 0.10ohms (40amps CDR, 20amps per battery, this is pushing safety, suggest stay above 0.14ohms), Parallel Dual Battery safest resistance with 25amp batteries is 0.17ohms (25amps CDR, 12.5amps per battery), maximum lowest that is advisable 0.14ohm (30amps, 15amps per battery). Parallel Dual Battery safest resistance with 20amp batteries is 0.21ohm (20amps CDR, 10amps per battery), maximum lowest that is advisable is 0.17ohms (25amps CDR, 12.5amps per battery). Series Dual Battery safest resistance with 30amp batteries is 0.56ohms (thats 15amps both batteries must support as if a single battery), maximum lowest that is advisable 0.42ohms (that's 20amps CDR both batteries have to support as if a single battery 66% max capacity).****

    LG HB2 - True 30amp CDR, 1500mah, powder blue in color. By specs these appear to be much like the HB6.
    LG HB4 - True 30amp CDR, 1500mah, milk chocolate brown (old version), mustard yellow (new version). By specs these appear to be much like the HB6 and HB2
    LG HB6 - True 30amp CDR, 1500mah, a cream white in color (old version), pink (new version), this is the coolest running battery on the market when under heavy load, making much safer than the VTC3 by far, get some of these you will really like them
    Sony VTC3 - True 28amp CDR, 1600mah, a matte pine green color
    Sony VTC4 - This is a long time standing King and Jack of all trades, 20 to 25amp CDR battery capable of holding and sustaining, but not suggested to do so all the time 28amp CDR, 2100mah, a matte pine green color like the VTC3, try to stay below 25amps

    ****Ohm's Law Formulas Used For the Following Regulated Mods- Triple Battery Series (Watts/9.6volts/90% Mod Chipset Efficiency=Maximum Amps), Dual Battery Series (Watts/6.4volts/90% Mod Chipset Efficiency=Max Amps), Dual Battery Parallel (Watts/3.2volts/90%=Maximum Amps), Single Battery Mod (Watts/3.2volts/90% Mod Chipset Efficiency=Maximum Amps).

    ****In My Opinion, just like a mech of any sort, these guys need 30amp batteries at all times****
    LG HB2
    LG HB4
    LG HB6
    Sony VTC3 (note, being safely 28amps, max 180 watts)
    Sony VTC4 (note, being safe but not advisable, max 170 to 180watts)

    120watts to 160watts Dual Battery Mod(Sigelei 150watt, IPV3,etc)
    ****In My Opinion, these bad boys need at least 25amp CDR batteries if you are going to run at this level regularly****
    Sony VTC3
    LG HB2
    LG HB4
    LG HB6
    LG HD2 (purple) - 25amp CDR, 2000mah / LG HD2C (salmon or skin color) 25amp CDR, 2200mah- these have been around a while, nice battery, rated 25amp CDR, personally I'd trust it at 20amps like most of LG's line excluding the HB Series
    LG HD4 (salmon or skin pink) (no manufacturer specs at the moment), independent tested 25amp CDR, 2100mah. By Mooch (a professional battery tester) these batteries rated right in between the HD2 and HD2C for Mah, same CDR, but was stronger than the HD2 Series, haven't tried these myself, but those are strong results
    Sony VTC4
    Sony VTC5A - (matte pine green), 25amp CDR, 2500mah. Sony has come out swinging at LG with this re-vamp of the VTC5. Sacrificed 100mah and boosted the CDR by 5amps, this bad boy gives the LG HD Series some serious competition, another rock solid battery Sony adds into their line up of 5 models now.

    75watts to 120watts Dual Battery Mod
    AW IMR 18650 2200mah - 20amp CDR, re-wrap yes but AW is a longest time trusted battery out of all other brands on the market
    AW IMR 18650 3000mah - 20amp CDR (by specs alone, this quite possibly be an A Bin LG HG2 or Samsung 30Q under the wrapper), still a re-wrap yes, but AW does not over spec their batteries
    LG HB2
    LG HB4
    LG HB6
    LG HD2 / LG HD2C
    LG HD4
    LG HE2 (wine red color) and the LG HE4 (yellow) - 20amp CDR, 2500mah - both of these models are solid batteries, and are great contenders to the Samsung 25R and Sony VTC4, balance of run time and decent CDR in this application
    LG HG2 - 20amp CDR, 3000mah, chocolate brown - LG has 4 highly impressive batteries on the market, the HB Series, and here the HG2. The HG2 is a great battery, with 3000mah and can do 20amp CDR this battery is like the VTC4 in the 20amp and below category, great run time and great CDR, best of both worlds.
    MNKE 18650 - 20amp CDR, 2000mah, orange - Before the Sony VTC3 hit the market, MNKE was the King of High Drains, only available cells left are the US Spec 20amp 2000mah, great battery, but becoming hard to get, its bigger 26650 brother is also a great King in the 26650 market
    Samsung 25R - Here is another workhorse like the VTC4, they can be used up toward 120watts with no issue, but highly not suggested - 20amp CDR, 2500mah, Rev2 and Rev3 (light blue), New Rev 5 (light green)
    Samsung 30Q - 15amp to 20amp CDR, 3000mah, pinkish purple or lavender in color - next to the LG HG2, or a 26650, 3000mah is nothing to shake a stick at, this like the HG2 gives great charge time and a decent CDR, rated at 15amp CDR, can wiggle it from time to time up to 20amp CDR, not suggested all the time, for the median wattage and below tier this battery really shines
    Sony VTC3
    Sony VTC4
    Sony VTC5A
    Sony VTC6 - (matte pine green) Factory Rated 15amps like the Samsung 30Q, independent tested 19amps CDR, 3000mah - this was released about the same time as the newer VTC5A, and Sony made a great answer to the LG HG2 and Samsung 30Q. Run time all three are about equal, but by tests the 30Q tops this chart followed by the HG2 and trailing in the back is the VTC6 due to its CDR, still a great battery and answer to compete with the LG and Samsung entries, max watts 54.7watts for this battery by iteself, 109.4watts in a dual battery.
    XTar High Drain XVTC4 - VTC4 clone, 20 to 25amp CDR, 2100mah, black and yellow - this is an authorized clone of the VTC4, Xtar bought the specs for the VTC4 from Sony, I'd trust them up to 25amps no higher though rated by Xtar for 30amps.

    65watts to 80watts Single Battery Mod (This is a dangerous category on a single 18650, as most of the easiest available batteries out there are 20amp CDR, this category needs 25amps up to 30amps CDR so the list narrow)
    LG HB2 (Up to 90watts)
    LG HB4 (Up to 90watts)
    LG HB6 (Up to 90watts)
    LG HD2/LG HD2C/LG HD4 (Up to 72watts Max)
    Sony VTC4 (Up to 72watts max)
    Sony VTC5A (Up to 72watts max)

    65watts and below Single Battery- Here the field is fully open

    ****I will update these lists on battery models as newer models and information become available****

    Battery Chargers - Always, always, always buy the best charger you can, when charging a battery is at its most dangerous state, take the analogy of you are putting pressure into a sealed can through a pin hole when charging a battery, this builds up heat, but any rechargeable battery resists having power pushed into it, so this state makes them a bit grumpy and unstable, never leave a charging battery unattended, have your charge on a fire resistance surface in case of trouble. When it comes to chargers, there are 3 main manufacturers you should only consider for the price range most are willing to pay, there are higher chargers in the RC world and such that out do these brands listed like Pila, but these listed brands work well and are reliable.

    Nitecore - the 4 models always suggested are the "i2" "D2" "i4" and "D4", the D2 and D4 are newer designs with digital displays over the i2 and i4, their charging algorithms are not much different from each other. Nitecore chargers can be found relatively cheaply, for instance an i2 2bay can be found in the 10 to 15USD price range, the D4 around the 35USD range upper scale. Great chargers, intelligent chargers, they detect battery type, charge level, and condition batteries in a trickle charge method, thus they charge slower than most, this is real gentle on batteries, thus why they are so reliable.

    Efest LUC - this includes the LUC2 and LUC4. These are bit more pricey than a Nitecore, but they are great chargers, better than the batteries they sell IMO. They have digital read outs to display charging state, battery charge level on each bay, they also have flexibility, some even come with car cigarette lighter plugs you can use them in an RV or your car while on the road, as well as you can change their charge mode from 0.5amp per channel, 1amp per channel, or 2amp per channel 2 center channels only (excellent for 26650 batteries in 2amp mode), but I highly suggest for 18650s 0.5amp most times, need a rapid charge 1amp mode max, 26650 batteries 1amp trickle charge mode and 2amp rapid charge when or if needed desperately, make sure you have plenty of batteries in rotation so you are not needing to rapid charge all that often, rapid charge decreases battery life, be kind to your batteries.
    Blu6 OLED - This is the LUC4 with 2 extra battery slots, an OLED screen, simple control buttons, a nitetime lights off feature, and bluetooth 4.0 support to communicate with an Android 4.4 or higher/ Apple iOS (iPhone/iPad/iPod) device app. Max current it can handle is 4 amps total load, bay 1 and 6 support 0.5/1/2 amp output, all bays support 0.5/1amp load, info is displayed on the OLED screen which scrolls between each bay 1 at a time or via the bluetooth app, with simple blinking LED lights for each bay when charging. These lights function as buttons along with another button right next to the OLED screen that controls lights on/off, and charge mod with the combination of bay # button/control button. All functions can be controlled more user friendly via the bluetooth app. The bluetooth app itself is very informative and higher detail, front screen all bays showing status (occupied bay/non-occupied bay, charge level of each bays, charging current, charging percentage, turn OLED on/off), selecting a certain bay allows adjusting charging current for that bay, also a graph of how the battery has charged thus far). Very nice charger like the LUC4, just a little pricier with 2 extra bays and bluetooth support.
    New LUC6 - This is the Blu6 without the Bluetooth support, mainly operates functionality similar to the LUC4. 6bays, with the following options Bays 1 and 6 (0.5, 1.0, or 2.0amps charge modes), Bays 2 through 5 (0.5 and 1.0amp charge modes)
    New LUC Blu4 - This is the LUC4 with added bluetooth like the Blu6 above, battery orientation is set at about a 45 degree angle instead of straight verticle or horizontal

    Xtar - This is the king of vaping charger brands. Great quality, great functions, rarely see any problem arise with an Xtar, and they have the largest selection of chargers on the market. Like the Efest LUC, they offer 3 power settings, 0.25amp, 0.5amp, and 1amp, range in models from single bays up to 6 and 8 bay chargers, they are pricier than any other manufacturer for a reason, quality, great warranty, intelligent charging, just a great brand, I could fill a paragraph of praise on them. You get what you pay for in the end.

    ****This list will be updated if any new manufacturers worth using become available****

    Any questions, comments, or additions, don't hesitate to post a reply here or PM me a message, any and everyone is welcome to use this blog post to link to as an answer to a new member, an I highly hope you do, knowledge is a very powerful tool.

    June 06, 2016 Follow-up (Battery Lists Above Are Still Applicable, given newer types of mods, I am listing according to type of Mod, note that I forgot to add when first made this post, Excluding AW IMR and the Xtar XVTC4, no other re-wrap brands are listed in this post)

    My personal battery brand trust levels aka how I rate a battery by its brand first

    #1 - LG (Given in just the past couple years LG has put some majorly impressive batteries on the market, it is also the number of batteries they have released that pass muster with me, their whole line is rock solid depending on the application they are used, the HG2 one of the most suggested batteries, the HE and HD series are the oldest models on the market LG produces, and their highly powerful HB series knocks the long time reigning champ Sony down a peg in my book)
    #2 - Sony (Sony only has 5 in the line up, but the VTC series if you use them right are still some of the best batteries on the market, the VTC5 was the reigning long mah decent CDR battery on the market for 20amps CDR and below, the VTC4 is still one of the most flexible batteries on the market, only LG's HD2 and HD2C give it any competition depending on the application but still the VTC4 is still one of the best batteries in the mech/unregulated/dual battery arena, then with their VTC3, in a mech or other 30amp CDR application, only the LG HB series outshines the VTC3), though as of Summer 2016 Sony has added their re-vamped VTC5A out to compete with LG's HD Series, and the VTC6 to compete with LG's HG2 and Samsung's 30Q, Sony is holding on with tooth and claw against LG as to their line up is between LG (9 models) and Samsung (2 Models) with number of models on the market (5 models now on the market by Sony).
    #3 - Samsung (There is no denying the Samsung 25R has been strong competition to the LG HE series, and Sony VTC4, it gives a lot of competition to the Sony VTC4 in the flexibility department, able to equal the LG HD2/HD2C in CDR output, it out shines the VTC4 and HD2/HD2C in the mah department, then the 30Q is LG's only competition to the HG2, but still a solid manufacturer)
    #4 - AW IMR (AW has been around a long long time, longer than Sony has been in the vaping scene, just read the mah and CDR of the battery to choose the right one. In a Provari 2.5 or earlier, Reo Squonk box, or other mod that needs button top batteries, here AW really shines, especially in the 18490/18500, and 18350 arena which pulls them up the list)
    #5 - MNKE (MNKE is another set of batteries been around on the market a lot longer than Sony and were the reigning champs before the VTC3 hit the market, in the 26650 market, MNKE in my opinion is still the king in that arena)
    #6 - Xtar's XVTC4 (This lone battery entry from Xtar is only applied as Xtar has approval to legitimately clone the Sony VTC4 and licensed from Sony the actual design/production sheets of the VTC4)
    #7 - Subohm Cell (You still have to use caution here, but Subohm Cell is just a re-wrapped LG HE2/HE4, and they mostly use A Bin from LG, not B or C Bin, but still be cautious)
    #8 - MXJO (I have used these myself, earlier 2500mah yellows, they appear to use A Bin HE2/HE4 and 25R's as well as HG2's, save yourself some money and go with the LG's and Samsungs instead)
    #9 - IMRen (I've used some of these for testing purposes, but like MXJO, better off saving money and go with authentics)
    #10 - AWT, Basen, Eizfan and the rest (They rate just two up from Efest Batteries IMO)
    #11 - Vamped (One of the first re-wraps after Efest tried flooding the market, if used right they were good, but just the slightest abuse they will go off like a roman candle, leave them be)
    #12 - Efest (Not even going to go into detail, Efest is the worst offender, more Efest re-wraps have gone boom than any other manufacturer on this list, I wouldn't even pay 10 cents for a single Efest, I'd pay 16 Dollars more on an LG at a brick and mortar before I'd waste my cash on an Efest battery)

  4. I repeat this often enough think it time to write this out then link to it from now on. I have used Kanger tanks for a long time, started out with their version of the CE5 the T2, then moved to the original version T3 when they first came out, and have used all of their products to date excluding the UniTank and will probably not move to the Protank3 when it comes out, I've rebuilt a Protank and T3S head dual coil already, wasn't really happy with it. The Kanger style Bottom coil is relatively a simple design to learn to maintain once you learn the ins and outs and learn to troubleshoot and work out the quirks and flaws, these tank systems are solid performers and are run and gun when working properly and in tip top shape. One of the easiest to use really, this post will cover the Kanger T3, MT3, Mini T3, Mini MT3, T3S, MT3S, Mini T3S, Mini MT3S, Evod, Protank, Mini Protank, Protank 2, Mini Protank 2, and Mini Protank 2 Version 2 mainly, though the same steps will work with any tank that uses the Kanger coil head, like the G50 (Hypertank), Tatroe Tank, UniTank, and will work on the Protank 3's dual coil head, top coils like the Kanger T2 (CE5) or any other top coil design like the Vivi Novas, iClears, CE# tanks with removable coil heads, this is general knowledge that can work.

    I classify cleaning into 3 types, basic, intermediate, and full cleaning.

    Basic Cleaning -

    Basic cleaning is just a simple rinsing and cleaning. Disassemble the tank into its basic parts, base, tank, and coil head, in the case of the Protank 2, Mini Protank 2, and Mini Protank 2 Version 2, top cap, central air shaft, and drip tip. Once disassembled to these basic parts, carefully rinse and run all the parts under warm tap water, on the coil heads run water thoroughly across the exposed wicks and down through the coil chimney to get a thoroughly cleaning of the wicks and coil, generally when the wicks turn white again they should be pretty clean. Now using a towel or paper towels you can get all or most excess water off the parts, tanks and other pieces you can reassemble, coil heads set them aside to air dry on a paper towel out of reach of little children and pets. Coil heads can be used imediately, but will take a few minutes of use to get excess water in the wicks burned out and flavor and vapor output will be muted. This should be done to your heads regularly after each tank for darker, sweeter, and thicker liquids, thinner, lighter, and less sweet liquids this can be done every 2nd or 3rd tank refill or when you feel the coil is not perfoming or could be clogged and gunked up.

    *Note - Pipe cleaners work real well on the T3, MT3, Mini T3, and Mini MT3, Protank 2, Mini Protank 2, and Mini Protank 2 Version 2 central air shaft; Evod, T3S, Mini T3S, MT3S, Mini MT3S, Protank central air shafts, cotton swabs (q-tips) work excellently.

    Intermediate Cleaning -

    All the steps of the Basic Cleaning get done here, however do the basic cleaning after. Intermediate cleaning you add in a soaking of the coil heads and glass sections for those tanks with glass in vodka, everclear (pure grain alcohol), or moonshine for about 20minutes to help dissolve gunk and sugars out of the wicks and off the coils. Other parts like plastic tanks you can soak in hot water, or if you do not wish to use vodka or such to soak with all parts soak in hot water, then do all the steps in basic above. This should be done to coil heads once a week, and clears out more gunk and goo out of the wicks and off the coil, especially with a vodka or everclear soak and the alcohol dissolves a lot of this off the coils and out of the wicks.

    Full Cleaning or Advanced cleaning -

    You do all the steps in Basic and Intermediate. After the Intermediate soaking, rinse your coil heads and bases. Next step attach your coils to a base, then gently wiggle the air chimney tube off, setting it and top seal grommet aside. Now inspect your wicks and coils. What we are looking for is in the wicks themselves, you will notice there is possibly still goo or gunk in them, or they are still dark, especially near the coils or around the coils, this is fine, it is just stubborn gunk, however, if the wicks appear to be frayed to the point they are literally desintigrating or you see dark almost blackish crystalizing then the wicks are bad and the head needs replacing or rebuilding, no crystalizing or desintigrating, attach the coil head and base to your device, on variable power devices, set this to the lowest voltage the device can do. Now, looking down from the top, slowly, in 5 second pulses, fire the coil up, the coils will start to sizzle and vaporize any water away first, then start to vaporize off any goo and gunk, after that the coils will start to burn off all carbon encasing them, exposing the wire again, do this until the coils all glow evenly, once this is done, re-attach the chimney to the coil cup, seating the sealing grommet to where it just begins to grip the coil cup, proceed to doing your basic cleaning under tap water to rinse out ash and burned off carbon. I generally do this any time I do intermediate cleaning which is once a week.

    These maintenance steps should add extra mileage to your Kanger tank systems and coil heads, just a little TLC can give great results to your equipment =)

    *Note - for top coil or other tank and coil designs of clearomizers, all of these steps listed will work, just modification of the methodology comes into play, ie for instance Vivi Nova and first generation iClear style (haven't done this or own an iClear30S), attach base, stem and coil head on without top caps or tank tubes to do the Advance dry burn technique will be different.
