As mod users, we depend heavily upon batteries. To assist novices to choose which battery to use in their mod I have written this guide. Our choices are IMR, protected ICR Li-Ion, and a new class of Hybrid batteries.

High quality IMRs are currently recommended in place of protected ICR Li-Ion for all applications. reference - Rechargeable Batteries

IMR (Li-Mn) are the safest batteries available for vaping. They use safer chemistry, so they don't require a built-in protective circuit like ICRs do. They have higher tolerence to stress, and although they may vent during failure it is less likely to be as dramatic as a ICR. Should protective circuits fail in ICRs they can vent violently in flames and possibly explode. ICR battery explosion

  • Lower Quality Brand-Name Batteries. Trustfire, Ultrafire, and Surefire are a lower-tier name brand battery in terms of quality and safety. Not recommended.



  • ​Generic Batteries. ​Not recommended. Seen at Amazon & EBay at cheap prices or thrown in for free in a kit when you purchase a mod from China. These are unknown batteries of unknown quality by an unknown manufacturer, and not worth the risk using in your mod. Never assume because they were included with your mod that they are safe or the correct battery to use.




  • If uncertain about the quality or type of a battery, don't buy or use it. Do not use over-the-counter batteries like those from Radio Shack, etc. Buy only from trusted e-cig vendors such as RTD Vapor AW Batteries. Use the type of battery that your mod calls for. For example, Provape recommends using only AW IMR button top batteries in the Provari; using magnets on flat top batteries will void the warranty because this is an unsafe battery practice.


  • Battery Chargers. Get the best charger that you can reasonably afford. Statistically most battery incidents occur while charging. Pila, Xtar, and Nitecore Intellicharger ​are the most recommended brands.


  • Always use safe battery practices and common sense with all batteries. Even the safest battery available to us can fail. IMR battery failure Most battery failures are the result of rapid discharge, either from the fire button inadvertantly pushed for too long, or the battery being shorted from metal objects (keys, change, etc) completing the circuit when carrying a battery in a pocket or purse. Use Battery Cases. Do not stack batteries.


  • If you are using sub-ohm coils in an RBA/RDA, it is extremely important to use the highest quality IMR battery. Coils < 0.8 ohm require an IMR battery that has a maximum continuous discharge rate over 10 amps​. This is extremely critical. Sub-Ohm Battery Chart

PROTECTED or IMR BATTERY: ​Which is best for your application?

IMR Li-Mn. Lithium manganese batteries. Also called "high drain", "safe chemistry", "unprotected".


  • These are used in regulated mods that use buck boost circuitry to achieve variable voltage-wattage, but they are now also recommended for single voltage mechanical mods as a safer alternative to protected Li-Ion batteries.


  • This class will have less capacity in mAh rating compared to protected batteries, but are superior when maximum load current is required, such as in regulated mods, mechanical mods using a Kick, or using an RBA. Why High Drain Batteries?

Hybrid batteries.

  • New mixed chemistry batteries that are both safe chemistry/high drain and extended capacity in one. A good choice for applications that demand both maximum load current and longer battery time. Can be used for either mechanical or regulated mods. Some of these have 20 or more amps continuous discharge rate which are ideal for sub-ohm.

Protected ICR Li Ion. Lithium ion class batteries, also called "protected batteries".


  • These batteries are now considered obsolete for mod use because of their potential for flames & explosion.

    Ok, this is just a verification question, as alot of tech jargon is confusing to me since I experienced a cereberal hemhorrage 8 months ago.

    Battery used : NCR18650PF 2900mAh 10A
    Equipment used on : 2 eVics, 2 "Fallen Angel" Mech Mods (EhPro EA mods named that by LiteCigUsa)
    I use coils ranging from 1.2ohm minimum to 1.8ohm maximum.
    The question mostly relates to the mech mods, the ohms calc says that at 4.2v on a 1.2ohm coil I am pulling 3.5amps and 14.7watts max which obviously drops as the battery discharges over time. The eVics are paired with genny's and the FA's are paired with either an igo-w or an Origen clone. The question here is, are these batteries acceptable for the conditions they are being used in?
    I also have a vtr on which I use 1.7ohm carto tanks (tank on a tank lol O.o) with NCR18650B panasonic batteries., generally around 9 watts. Are those acceptable batteries for that application as well?

    I should add (via edit) I dont at this time use a kick, tbh, Im not sure a kick is useable in the "FA" mod

    I appreciate the time and effort spent for the original posted info.

    Retro68: All the batteries you listed are acceptable for the applications you listed. I'm not a big fan of the Panasonic NCR18650B 3400mAh batteries, as they are more applicable to low drain applications like a flashlight. They are not a high-drain battery. However as long as you are using them with factory-made coils (1.5 - 3.0 ohms) on a mech mod, they will suffice. With the VTR being a regulated mod, it would perform better with a true high-drain battery.

    Baditude,
    I figured I'd come to you with this question as I've been struggling for an answer.

    I currently own 2 Efest button top IMR 2250 mah 18650 button top batteries (10 amp max). I also bought two SONY 3.7V US18650VTC4 2100mAh HIGH DRAIN 30A batteries flat top when I got my Nemesis mech mod (which I absolutely love) with upgraded magnetic switch.

    I've noticed something odd, however, with my kick that I have. It is a kick clone 5-12 watts. It plays very nicely with the Efest 2250 mah 18650 and the Efest 800 mah 18350, both with button tops. The wattage I set, usually around 9 watts for my PT2, vapes perfectly. However, when I switch to the hybrid Sony batteries that are flat top, it scorches the pt2 coil no matter what setting I have it at.

    My question is this: does the magnetic switch + flat top battery cause this? Or does it have to do with the interaction of a flat top battery with the kick? Or is it because they are hybrid batteries and not pure IMR batteries?

    I know the last possibility is that it simply is a freak occurrence that both my Sony batteries don't play nice, but all 4 of my efest button top batteries are fully functioning.

    I should note that when I use the Nemesis w/ magnetic switch without the kick, i always use the Sony hybrids and they work sensationally -- they have 1/2 the voltage loss under load than the efests do, which is always a bonus.

    I look forward to your response.

    Ty for the quick reply. I use the Kanthal readywires from SVC as opposed to factory made coils. The only premade coils I use are for the cartotanks. The readywires help me alot since my dexterity isnt what it used to be lol. Looks like I will have to get a few more of those NCR18650PF batteries. I use em in my evics and mechs but I need more for the vtr if they are ok for that. The evics run the 1.5 ohm genny's and the mechs run the 1.5ohm rda's lol. I find myself using the mechs the most tho.....

    To brookj1986: I have to admit I don't have an answer to your question. I use primarily regulated mods so my experience with mechanical mods is somewhat limited.

    No worries, figured I'd ask. I don't think it has anything to do with the little magnets in the switch . I also an fairly confident that it doesn't have to do with the chemistry of the hybrid battery versus the true IMR... I mean, if it can be used in a mech mod or regulated mod, why not with a kick... Especially with a high quality battery like the Sony ones are. My assumption is it's simply my kick not liking flat top batteries (or simply because I didn't spend the money for a high end kick. Since my less expensive batteries work fine with the kick, I'll continue to use them until I can get a better kick.

    Hello Baditude, any opinion on the Samsung INR18650-25R 20A? Thanks in advance.
  10. Baditude's Avatar
    To ipodah: "Samsung's answer to the Sony Konion US18650VTC4". Same mAh rating as the SonyVTC5 with 10 amps less continuous discharge rate. It is an unprotected IMR/hybrid, safe chemistry, & high drain. It should be a nice battery to be used in applications requiring a high drain battery with a nice capacity between charges. If you are doing extreme sub-ohm builds, make certain to use the Ohm's Law Calculator to insure you don't go over its 20 amp limit.

    I don't do extreme sub-omh builds myself, I just wanted to know if these batteries would fit on your recommended list as I frequently use it as reference when answering questions on a French forum. But thank you for the reminder and for your answer. Highly appreciated.

    Thanks for the great advice!

    I'm getting ready to upgrade my batteries, no need to, it must have been the cheap ThreatFire charger that ruined the ones that I have. The two AW IMR 18490 3.7V 1100mAh batteries , with my whole mod setup, were just purchased in January.

    I was told they were good batteries, but the charger likely fried them.

    The batteries that I were looking at for my Astro mod (clone) are the AW IMR 18650 3.7V 2000mAh, which would be an upgrade. I still may buy them, but not until I get a quality charger first. I have no issue with paying an extra $15 for a decent one & I don't want a cloned one, which is why I'll stay away from eBay & buy from a reputable e-cig supplier.

    Irecently got the same Sony batts for my KTS, first tube mechmod, as well as AW IMRs. The AWs work OK in the mod with my PTanks but had the same coil scorching effect with the Sony's. But more than that the Sony made the firing button overheat severely real fast as well as arc with visible spark flying out the button. On my VV device the fully charged Sony's were scorching PT coils at any setting like you said. So I'm thinking its something with these Sony Batts in certain applications. Comments are welcomed as I'm perplexed also.

    I don't really understand batteries after reading this thread. I didn't know that there were different mAh ratings and high drain/low drain.

    I have a Russian 91%, built to 1.08 ohm, I use on both a K-101 and a Silver Bullet. Right now I have 2 green 18650 2100mAh 3.7V batteries. Is there a better battery out there for my setup? Should I get high drain or low drain? I only use protected batteries.

    You should use only high-drain, safe-chemistry batteries. These are a huge improvement over the proteced ICR batteries and much safer for use in a mod. There is no reason to use a protected ICR battery with the advent of the newer IMR and hybrid batteries available to us.

    I don't know which battery you are currently using. Just saying you are using a green battery doesn't tell me much information. And I don't know of any protected battery which is green. I'm rather surprised that you are using a rather advanced juice delivery device (Russian RBA) with homemade coils and you haven't learned more about batteries at this point. Kinda scarey, actually.

    PM me if you need more information.

    I have started using a brand of battery charger that I found good reviews on-- Soshine. They are not inexpensive I paid $20 for a single Bay Soshine SC-S7 Charger from Illumination Supply LLC. I watched a video on YouTube about this Charge by = Julian Ilett= seems to be some kind of electronic expert--I am referring to the single Soshine single bay charging only

    Great guide thanks. I'm using VTC5s at the moment. Can I get batteries that will last significantly longer than VTC5s? I'm not bothered about sub ohming and tend to build at 1.0 - 1.3 ohms at the moment. I'm kind of tempted by orbtronic or panasonics with mah ratings of 3400 or 3600mah. Is there any reason I shouldn't get these for mech mods / DNA 30 mods?

    The manufacturer of the Evolv DNA chipset recommends using a battery with at least 12 amps continuous discharge rate. This means using a high drain IMR 18650 battery with OVER 10 amps continuous discharge rate (see above list).

    The batteries which typically have more than 3200mAh capacity are ICR Li-ion batteries which are not high drain and have extremely low amp ratings. These batteries are best used with flashlights. It's important to note that ICR batteries are not safe chemistry and can vent flames or possibly explode should they dead short in a mod. I consider ICR Li-ion batteries to be of obsolete use for mods.

    The new Panasonic NCR18650BD battery is an IMR/hybrid with 3200mAh and still has 10 amps continuous discharge rate. A typical regulated mod (non-DNA) should have 10 amps for the PWM circuitry to function optimally. This battery is a good choice for both a regulated mod or a mechanical mod for general purpose applications.

    The Panasonic NCR18650A and B batteries (3100 and 3400 mAh respectively) are IMR/hybrids but are not high drain batteries and only have 6.8 amps continuous discharge rate. Their chemistry is highly weighted to the ICR side of the fence. These batteries are adequate only for factory-made coils (1.5 - 3.0 ohm). These two batteries were designed for flashlight use.
