Beginner on Rebuildables. Help?

[KEVOLO]

Hey what's up,

I'm a beginner in rebuilding atomizers and need help!


I have a Sentinel V2 Telescope mod, with an IGO-W and a 18650 battery...

I currently know how to rebuild the atomizers ( like with the wire and silica or cotton), but I don't really understand the whole thing on checking it on a meter... I've been using a creation of mine that is at .3 ohms (checked it on my variable wattage Tesla mod) , I want to get deeper in building my own and my friends atomizers... If you can help me I'll be most grateful for your knowledge.

I guess what I really need to know it about the ohms, and battery voltage things, and gauge wire and so. Lol.

That my dear Watson is a recipe for disaster.

I would suggest you drop by the link provided below and do some reading as the lack of knowledge can hurt you if you are not careful.

First off, I'd like to know exactly which batteries you are using?

Next, you should be starting off with a safer resistance coil than sub ohm right off the bat. Until you know more about what your battery limitations are, you are getting in deeper than you should be and getting into dangerous territory.

You should NEVER make a coil which will pull more Amps than it can supply, or the battery will self-destruct into thermal runaway.

A 0.3 ohm coil will pull 14 Amps from your battery. Can your battery safely handle that?

 

[dice57]

yeah make sure you have a good understanding of the amp limit for your batteries. a .3 ohm coil will draw 14 amps from a battery, which if you are using a 6 amp ratted battery, would quite possibly mean you just took you last vape. The minimum battery I'd vape that build on is a 16 amp continuous rated battery, in new condition, I'd be happier with a 20 or 30 amp rated battery, safety margin. .3 ohm is a serious low sub ohm build, would need an excellent rba or rda that could wick enough juice to run it. Not something for a first time builder to mess with, and won't even fire on a regulated mod. Would recommend doing 1.5-2 ohms for your first build and save sub ohms for when you are well versed in batteries, ohms law, and safe vapors technique's. http://www.the12volt.com/ohm/ohmslawcalculators.asp#power

Damn, bad beat me by 4 minutes.

As the others here have said, please check your batteries limitations. Unless you are using MNKE, Orbtronic, or a few other high-drain batteries, .3 ohms can be very dangerous. Find out what type of battery you have, research it's amp limit online, and stay within those parameters. If you google "ohm's law calculator" you will find great little tools to help you find the amp draw of the coil youre building. Purchase a multimeter, resistance checker, or a regulated mod (VAMO, Provari, SID, etc.) that will tell you your resistance of your newly made coils. Always check a coil with a resistance meter of some sort before using it on a mechanical mod. I purchased a multimeter from a local hardware store (harbor freight tools) for $9. I also double check with my regulated mods before firing that coil. You can get an ohm meter from a lot of vape sites like kidneypuncher.com for around $20. Fasttech also has one for around $10 but it takes longer to ship since it is coming from china. If you insist on sub-ohm vaping (like i do ) for God sakes, get you some high amp limit batteries like MNKE 18650s or Orbtronics. i personally use Orbtronic 18650s that have 10 amp continuous, 18 amp pulse limits and they are great. Good luck, hope this helped, and VAPE SAFELY! Your eyes, ears, and nose are much more important than blowing plumes of vapor.

Hey thanks for all who have posted. I'm currently using an IMR 18650 2200mah 3.7V ... I have two blue ones... One for my mechs mod and the other for my tesla ...

I'm reluctant to comment on these batteries. Samsung makes a hybrid battery that is 18650 that is 2200 mah, but their name is clearly on the battery and the color is more teal than blue, so I can't say your batteries are those. Sorry, need the manufacturer's name before advising further. Where did you get these?

That's all it says on the battery side. They both came with my Tesla Mod....

I'll have to agree with everyone here on the coil building, if you want to build your own coils maybe start @ 1.5 or so and work your way down from there. You might find you can get the vapor production from a higher resistance coil that satisfies you. If not do some research and make sure you have the proper equipment before venturing into the sub ohm. I find I can't tell much difference between 0.3 ohms and 1.0 ohms in terms of vapor production other than it takes about a 2 second pulse on the 0.3 ohm coil to produce the same amount of vapor as a 1 ohm coil with a 3 or 4 second pulse.

 

[KEVOLO]

The thing is that I don't know where to begin. How do I get my Rebuildables to 1.5? What battery? Do I need a meter?

I've watched boring videos of which they say that they are going to sum up "Vaping and Rebuilding and What You Need to know", but I don't really understand haha

Hey Kev,
the resistance of your coil is going to be largely dependant on the gauge of the kanthal wire. 28 gauge is fatter than 32 gauge. 28 gauge will give you lower resistance with the same length of coil than 32 gauge (seems counter-intuitive i know). I prefer working with 28 gauge wire because it doesnt break as easily and holds it's shape better.
what i do is wrap my coils around a nail then feed my wick through the premade coil. This isnt the best method for ss mesh but works great for silica or cotton.
How many wraps you do will give you different resistances. For the size nail i use, 8 wraps of 28 gauge kanthal gives me around 1 ohm. 8 wraps of 32 gauge will give a much higher resistance (something like 2.0). The best way to find your sweet spot is to find something to wrap your coils on and write down how many wraps gives what resistance.
When I rebuild smaller coils like a kanger protank head i use a smaller nail so logically, more wraps.
Check Baditude's post up there ^ for an ohm's law calculator to see what amps your coil will be drawing and which batteries work best. Any IMR 18650 battery should be fine for 1.5 ohm and higher but double check the calculator because i have been known to be wrong. If you are using a regulated mod (provari, VAMO, SID, etc.) the device will usually have a safety feature that will shut off the device if you're drawing too much current. Mechanical mods don't have that feature so they are inherently more dangerous when building coils lower than 1.8 or so.
Hope this helps. Vape safe and God bless.

Edit: also, yes you should have a meter when rebuilding your own coils. most regulated mods have a resistance checker on them but if youre using a mechanical scroll up to my previous post^ for places you can get a meter. The reason for the meter is so you can make sure your coil will not short the battery(no bueno) before you fire it.

Here's a few tips:

Resistance:

-The thinner the wire, the higher the resistance.
-The longer the wire, the higher the resistance.

Battery safety:

-Stay away from unbranded batteries.

-Do not use more than one battery in a mod.

-Batteries have something that is called the maximum discharge rate aka amp limit. You need to know the max. discharge rate of all the batteries you intend to use with any rebuildable atomizer especially if you plan to do a sub ohm (lower than 1 ohm) coil. The list that Baditude posted earlier will come handy for that. Never go over the the max discharge rate.

-To make sure you are not going over the amp limit of your battery click this link. In the voltage field enter 4.2 and enter the resistance of your coil in the resistance field then press calculate. Now look at the current field, if that number is below the max. discharge rate of your battery... You are good to go. If not... Rebuild your atomizer or use the appropriate battery.

You should also avoid being exactly at or very close to the amp limit of the battery... Leave yourself some head room for extra safety.

How do I get it to 1.5? And will my 18650 2200mah 3.7v batt work with that build?

Well, if you can't identify the manufacturer or otherwise identify it by the letters/numbers on the battery, you can't assume that it is a safe battery to use in a mod. And unfortunately, you can't assume that a Chinese manufacturer/reseller knows enough about batteries to throw in the right battery for free in a kit. Trust me on that. Never use a battery in a mod that you can't identify as safe.

RBA's require using a "high drain" battery, whether you're using a regulated or mechanical mod. When choosing your next batteries, all of the batteries in my above list are high drain. The mAh rating determines how long a battery will last between charges (higher number, longer lasting). Do not use a protected ICR Li-ion battery (they are not on the list).

The Amp rating on a battery determines if it is safe to use for sub ohm vaping. Any coil that is less than 0.8 ohm should use a battery that has over 10 Amp continuous discharge rate. A coil 1.0 ohm or higher you can use any of the batteries which have a 10 Amp rating. RTD Vapor and Orbtronic are two vendors to find these batteries.

The gauge of wire (thickness) and number of wraps to make the coil determine the ohm rating. This will take some experiementation making a number of coils with a different number of wraps to get to the ohm rating you desire. Always measure the coil with a meter. I suggest starting out with 30 gauge wire. I do 6 -7 wraps to make a 2.0 ohm coil with 30g wire. http://www.vaporkings.com/category-s/3041.htm

You will need to obtain a digital multimeter and learn how to measure your coils in ohms and your batteries in volts. Never fire any coil you make without first checking the ohms and determining with the Ohm's Law Calculator that your battery can safely fire it. All of this info is in the previous links.

This is why RBA's are said to be for advanced vapors. You've got a LOT of personal research to do. I've included a LOT of info you need to know in the links above and in my previous post. I've done half of your work already for you. Good luck, and vape safe.

The longer the coil wire is the more resistance it will have (more coil wraps will make it longer). The smaller the AWG (gauge) number it is the bigger the diameter the wire and the lower the resistance it is per inch length.

There is a whole lot of information about this stuff here.

First thing first,

Do not use those blue batteries, I will not go into details, but do not use them.
You are in very unsafe territory with those batteries.
Email Orbtronic, or RTD ask for safe batteries for your setup.
This is only beginning of your high amp vaping trip.
Vape safe!

Does it matter how many mAh's ??
