Top 10 High Drain Batteries for Sub-Ohm Vaping

By Lindsay Fox Posted August 16, 2017

Best 18650 Batteries for Vaping


In this age of sub-ohm tanks, 150 W vape mods and cloud competitions, vape batteries need to be capable of putting out some serious power. We’ve addressed battery safety elsewhere, but the short version is that any given battery can only put out so much current, and if you ask for too much from it, you can have a very bad time (i.e. your battery venting and possibly exploding). That’s why getting the right vaping battery matters.


But finding the best battery for vaping isn’t easy. Our list of the best high drain batteries for sub-ohm vaping aimed to make that a little easier, but sadly it wasn’t entirely accurate. We made the mistake of actually trusting what the manufacturers said: with re-wraps (cells from other manufacturers clothed in another brand’s wrapper) and pulse amp limits masquerading as continuous amp limits, you have to be a lot more careful about which batteries you put in your mod. Thanks to several very helpful comments and a lot of research, we’ve put together a new list of the best 18650 batteries for sub-ohm vaping.


Best 18650 Batteries for Vaping


We’ve primarily focused on amp limits, but to order the list we also paid attention to capacity, and as well as the best 18650 batteries, we’ve added a couple of 26650 batteries to the list too (placed at the bottom because most vapers still use 18650s, despite the high amp limits and capacities of 26650s). So, without further ado, here’s our list of the top 10 high-drain 18650 batteries for vaping:


10 – Efest Green IMR 26650 (23 A / 4,200 mAh)


Efest 26650 Vaping Battery


Efest batteries are pretty popular in the world of vaping, but they aren’t one of the companies that actually make batteries. They take cells from other manufacturers and put their own branded wrapper on them. In general, these are lower-quality batteries and sometimes manufacturers (including Efest) overstate what they can do.


That said, not all rewraps are bad. In fact, you can still find some high-quality rewrapped batteries based on reviews and tests, and their 26650 option – the Efest Green – performs excellently and has a solid set of specs too. This is easily among the best 26650 vaping batteries on the market, with a 20 A maximum continuous current and a huge 4200 mAh capacity. The well-known battery expert Mooch tested it directly and found that the maximum continuous current may be closer to 23 A, so it’s one of the few batteries that can offer more than the manufacturer claims. You can pick this battery up for $12.95 (all prices at time of writing, August 2017)

9 – iJoy INR26650 (30 A / 4,200 mAh)


Best 26650 Vaping Battery - iJoy 26650


iJoy isn’t one of the big-name battery manufacturers either, but their 26650 powerhouse has a lot going for it. Although iJoy rate it at 40 A maximum continuous discharge, the more reliable, independently-established rating of 30 A still makes it a great choice for any vaper looking for the best 26650 battery for high drain vaping. With an impressive 4,200 mAh capacity, it’s a long-lasting option and it performs like an absolute beast. If you’re in the market for a 26650 cell, iJoy’s offering costs $12 new.

8 – Samsung INR 18650-30Q (20 A / 3,000 mAh)


Samsung INR 18650 30Q Vaping Battery


Onto the best 18650 batteries, the Samsung INR 18650-30Q has a slightly better than average amp limit – offering up to 15 A continuous discharge – and an excellent capacity of 3,000 mAh. This uses nickel chemistry (indicated by the “N” in the name), and testing suggests it actually performs reasonably well at 20 A, although it’s better to stick to the 15 A max recommendation for safety purposes. You can pick this battery up for $8.95.

7 – LG 18650 HE2/HE4 (20 A / 2,500 mAh)


LG 18650HE4 Vaping Battery


The HE2 and HE4 hybrid IMR 18650 batteries from LG both have the same core specs, offering a 20 A continuous discharge limit and 2,500 mAh capacities. The (yellow) HE4 is the newer model (and is actually called the LG DBHE41865), and shows good performance in tests at 20 A, although the capacity drops considerably when tested under the (not recommended) amp-load of 30 A. If you can’t find the HE4, though, the (red) HE2 is still a very dependable battery and may be easier to find in stock. Kidney Puncher claims that they’ve seen tests where the HE2 handles much higher currents, but available tests show a notable capacity and voltage drop when tested at 30 A. As always, it’s best to stay within the battery’s official limits.

6 – LG INR 18650HG2 (20 A / 3,000 mAh)


LG 18650HG2 Vape Battery



Also offering a 20 A maximum continuous discharge but providing 3,000 mAh capacity, the LG INR 18650 HG2 is up there with the best vaping batteries for sub-ohming. The only reason this isn’t placed above the HE2 and HE4 is that initial testing from Kidney Puncher suggests a fairly poor performance, dropping to around 2,100 mAh when tested under vaping-like conditions on a 0.2 ohm coil (meaning 21 A at the full 4.2 V). Still a great option for the amp limit alone, though.

5 – Sony VTC6 (20 A / 3,000 mAh)


Sony VTC6 18650 Vaping Battery

Sony’s VTC batteries always feature on lists of the best 18650 batteries for vaping, and for good reason. All of the incarnations do a great job of balancing high current output with battery life, producing a series of cells that perform excellently and are as dependable as they come. The latest cell – the VTC6 – might not have as high a maximum continuous current output as some older models, but the 20 A output combined with a huge 3,000 mAh capacity makes it one of the best 18650 batteries on the market. If you’re looking for a battery with a 3,000 mAh capacity, the VTC6 should be your number one choice. You can pick VTC6 batteries up for $11.95.

4 – Samsung INR18650 20R (22 A / 2,000 mAh) and 25 R (20 A / 2,500 mAh)


Samsung INR18650-20R Vape Battery


The Samsung INR 18650 (hybrid chemistry) 20R has since been upgraded to the 25R, but that upgrade came with a slight decrease in maximum continuous current. The benefit of the newer version is in capacity, with the 25 R offering 2,500 mAh, which still leaves the 20 R as the best high-drain option for sub-ohming if you only consider the amp limit. The decision is really between an extra 500 mAh capacity or an extra 2 A max discharge. Personally I’d opt for the 25 R for the capacity, but that’s ultimately your decision to make depending on what you need most from a vape battery. Testing shows that both cells do really well, so you’re unlikely to be disappointed whichever you shoot for.

3 – LG HD4 (25 A / 2,100 mAh)


LG 18650 HD4 Battery


LG’s HD4 is a viable contender for the title of the best 18650 battery for vaping, offering an impressive 25 A maximum continuous current rating (based on testing) coupled with a solid 2,100 mAh capacity. It’s pretty close to the HD2C when it comes to its capabilities, but it tops the older HD2 since it’s keeps it’s voltage longer during discharge – offering more consistent performance for vapers. Despite the similarities to the HD2C, it’s a great cell in its own right and is well worth considering if you’re looking for a high amp drain battery for your mod. You can pick up the HD4 for just $4 per cell.

2 – LG HD2C (25 A / 2,200 mAh)


LG HD2C - Best 18650 Vaping Batteries


The HD2C from LG is a 18650 battery that updates the HD2. While looks like a step down in terms of maximum continuous current based on the specs (which give a rating of 20 A compared to 25 A for the HD2), testing confirms that the ratings are probably underselling it. In practice, the HD2C is a 25 A battery, just like the HD2, and it also has a capacity that appears closer to 2,200 mAh than the stated 2,100 mAh. On top of this, it runs at a higher voltage in use compared to the HD2, putting it above it in terms of performance and landing it a respectable spot among the best 18650 batteries for vaping. You can buy the HD2C for $4.50.

1 – Sony VTC4 (20 to 30 A / 2,100 mAh) and VTC5A (25 to 30 A / 2,500 mAh)


Sony VTC4 Vaping Battery


Sony takes the top spot on this list of the best 18650 batteries for vaping because they’ve released so many excellent batteries over the years. The VTC4 and 5A are their best offerings for high-drain vaping, with a stated maximum current rating of 30 A on both cells. However, testing suggests that the 5A tops out at 25 A and the VTC4 is ideally used at a maximum of 20 A. Both of these can technically exceed these ratings (and be used at 30 A as the manufacturers suggest), but for longevity you’d be better off keeping the current slightly lower.


The short version is that the VTC 4 is a great option, priced at $23.95 for two cells, but if you can find the VTC5A in stock (available for $6.50 per cell at the time of writing), the improved 2,5000 mAh capacity gives it a little more potential. For high-drain vaping, Sony really does dominate the best vaping batteries.

Conclusion – Vape Safe


Choosing the best 18650 battery for vaping is partially about “chuckin’ clouds” and becoming your own mini steam train, but the reason it’s so important is ultimately safety. If you’re looking to draw some serious current from your battery, you need one that can stand up to it, and outside of in-built batteries in regulated mods, this means you need to understand what you’re doing. If you can’t already recite ohm’s law from memory, brush up on it and why it’s important before you go putting together a super-sub-ohm build and trying to fire it with an inappropriate battery.


If you know your stuff, then get yourself a dependable, capable vape battery – ideally one with a bigger amp limit than you really need, since it’s better not to push your battery too close to the limit – and go ahead and wow the crowd at your local cloud contest. Get one of the best vape batteries and you can have fun chuckin’ clouds without worrying about your mod turning into a pipe bomb.

    Sweet!! Looks like a good list. Do you know if Fast Tech is reliable for getting batteries? Never bought from them before. Not sure if their batteries would even work.

    • lol, I’ve never bought batteries from Fast Tech myself, but it looks like they have some good ones! The only problem is they also have some less reputable brands too, but if you stick to batteries from reliable manufacturers it should be absolutely fine.

      Although I’d personally recommend using someone like Illumn, RTD Vapor, Sun Vapers or KidneyPuncher for your battery purchases – they’re among the most reliable when it comes to ensuring you’re getting authentic batteries.

      • Ben Raaijmakers

        Try NKON Eindhoven Netherlands! Compared to the chinese theire prices are very reasonable and no fakes are ever sold.

    • Cat Tilley

      As long as you don’t mind a wait time of 30-40 days, also there’s an Air Mail option that will reduce this to 15-20 days, FastTech has some good deals. Though I’ve never purchased batteries there & never will, the handling can be poor, especially at the the NY postal center where these packages are often held for a week or more for inspection, leading to a damaged battery or other product.

      I knew of one person who ordered several items that has glass from FastTech & though they carefully packaged it, the inspectors didn’t place these back the way they were & half of the items were broken. That’s why the only items that I order from the site are metal only.

      There are way too many legit US vendors who has competitive pricing with 2-5 day shipping to be worried over US Customs poor opening & handling of items, not to mention the wait time, over half is often at the NY center. I’ve ordered from one of the sites that Lindsay Fox mentioned below (RTD Vapor) & they provide fast service with genuine products. Legit shops will not sell cloned or counterfeit batteries, however many on eBay does.

      I hear Fast tech sells lots of counterfit everything

    The constant refrain “be familiar with ohms law,” is annoying. It’s true-ish, but not really sufficient.

    My main problem is it’s a cop out. At the basic “familiarize yourself with ohms law,” bs it doesn’t at all begin to give newbies a bit of direction on safety. A law stating the relation between an electrical input, output and the resistance doesn’t at all encompass battery safety. At a more sophisticated level, a lot of unnecessary information but still not helpful for vape safety.

    It’s telling that both the people who listen to this advice and the people I hear give it, don’t really know the first thing about the most basic and yet dangerous element of vaping, the small metal cylinder filled with pressurized, flammable liquid powering the whole thing.

    This article spews a lot stats about batteries that was nice, but it doesn’t even begin to touch on safety (the smallest, vaguest section). While it repeats the refrain about “why ohms law matters” it curiously doesn’t spend the time to explain how it relates the battery safety either. It’d be FAR more helpful to just SAY how to exercise safety with a battery (spotting fakes, don’t over drain, how to avoid shorts for starters). I’m becoming convinced all the “experts” in the vaping community that pump these BS disclaimers don’t really know themselves.

    It’s just a continuation of the obsession for the best, most powerful components with only false lip service to safety that makes this far more dangerous than it should be.

  • Matt Kelly

    What your thoughts on Surefire and Fenix. I know they both make good stuff.

  • John

    Which 18650 batteries are recommended for the Smok X Cube 2 with a TFV4 tank Quad-coil? I want the most possible power out of the mod and I want the batteries to last long before changing them. Can I use 4200mah batteries and which is the highest Voltage on the batteries that I can use in this mod?

  • TheRealVapeIcon

    Rule of thumb high mah equals lower amp high amp lower mah. You can’t have both. Look for continuous discharge not max continuous discharge. Most 18650s like LG EFEST etc are only 20amps. Most are 20amps or lower. I think the Sonys are the only 30amp batteries available.

    • Seth Rall

      sony has 30 amp CDR? wrong!

  • Rasean Blyden

    How is it possible Efest 18650 25000mah isn’t on this list?

    • manufacturer2

      Efest makes an 18650 that’s 25000?!?!?!

      • Jordan Lee

        Clearly a typo of 2500 😉

        • manufacturer2

          Don’t play with vapers feelings like that. 😉

    • iHeretic

      Because Efest doesn’t make their own batteries. They’re all rewraps and not consistent among their lines by any means.

  • Adam S

    Kidney puncher sold me beat batteries! I purchased them based off of the link on this article and after one use they are beat. Drained after a couple pulls not even firing evenly…. DO NOT BUY FROM KIDNEY PUNCHER!

  • Tristan

    None of these are made by the above manufacturers , it’s all sub contracted work. It’s just like a PC , just because the hardware design configuration is say Dell for example, doesn’t mean Dell make the components. The more ‘performance’ based stuff will be made by the likes of Intel but the basic bread and butter stuff is generic chip manufacturers who are awarded their contracts based on cost , and if you’re lucky quality. That’s just the way to do things now and it keeps thing affordable for consumers. Sony haven’t been making the VTC for a good long while now, but the designs are to their original specification. To be honest as long as the designs are strictly adhered to with good QC , you’ll get the performance stated. The trouble is, like everyone, the manufacturer will constantly shop around for a better deal on the base components and materials to increase their margin and this is when you notice that maybe you got a ‘Bad batch’. If they notice complaints, then they go back to what they were using before because it’s in their best interest to keep selling them.

    • Billy Rogers

      Sony never quit making the VTC series, they tightened down oem distrobution, they said that to cover their ass because the batteries were not made for ecigs. Simple as that, Sony NEVER quit making the VTC battery.

  • TheMechanic

    They don’t make 30amp continuous discharge batteries. Words like maximum continuous discharge confuses people & pulse ratings also confuse people. It’s BS from sales people to market their product. If Sony stopped making a high in demand battery there must be a reason. They wouldn’t start back up. They sold off the right to someone else. VTC5s were pitched by every reviwer as the best & that it put out 30amps continuously. They don’t. They are 20amps. They stopped making 30amp continuous discharge batteries because of the dangers.LG is a subsidiary of Samsung. They make the best batteries. Not just 18650s but for computers cell phones etc. The vaping community should listen to smart people. You know, the guys with PHDs & stuff. Not some reviewer or vendor wanting your money.

    • TheGCU

      LG is not a subsidiary of Samsung.

      • Mark Landis

        True, and thank you for pointing that out to everyone. One of the problems with discussions of this nature is the tendency for participants to play loose with the facts. People see something printed and accept it as reliable and factual. I personally feel that when a participant misrepresents the facts, the entirety of his post is most likely subjective, and innacurate.

      • Jerry Mael

        They have products made at the same plant but you are correct.

    • Russell Rector

      Lg does make a 30 amp cont Hb2 , HB4 , HB6

  • Andrei Antochi

    LG,Sony,Samsung ….the 3 big…they sell the chemistry(recepy)to athers manufacturers like Keeppower,they make the batteries using the original chemistry and sell them using the original names,they are “original”

  • Brian Diffenderfer

    Ive heard the only true continuos 30A battery is the Sony VTC4, the VTC5 is 20A


      You do not discharge it continuously vaping,you hold button down ,take a hit and let go,even if you hold button down for a few seconds its not reall continuous.

  • athalla

    How about vappower?

  • JLA-Guy-Venger9090

    19000 mah battery i like get 40 of them

  • Craigs Lister

    The Very first battery listed at 1. is a 26650 not an 18650

    • Mike Santana

      the writer says he included 2 of them just too show in case someone needed them

  • Sean

    It seems like no one recognizes the red AWT 3000mAh 40A 18650 battery. I’ve used them for the last year. Time to get another set. But everything on this list pales in comparison to the amperage and capacity on the AWT batteries. Anyone else using them or have a different opinion?

    • John Blanco

      It is because that is an overrated rewrapped battery. It is not safe sir..reconsider continuing using this battery.

  • Glen McMartin

    There are no 40 amp continuous discharge 18650 batteries! Sony and LG top out at 30 amp but with that comes lower mah rating (there is no free lunch in the universe!)


    What about the Efest?

  • Arman

    How about xtar?

  • Exaco

    VTC5 is 20A..

  • Exaco

    First place definetely goes for LG HB4.. It’s true 30A and is able to pulse up to 60A. ( 5sec on/ 30 sec pause ) without damaging the cell. VTC5 would die instantly above 30A

  • フィリップ オルソン

    VTC5A can handle 35A so they would be nr1

  • The Sony VTC5 is rated for 20A continuous discharge, not 30A. Same goes for the VTC4. Only the VTC3 is a 30A cell.

  • James

    ⬆ well said! And very useful information on the rewraps. As im currently looking for above 20 amp battery to safely use below 0.19 oms . i was a little nervous fireing my Samsung 25r sence i pushing it a bit at 0.14 oms. I did a rebuild to 0.19 which ruffly puts the amperage at around 20. Question? Efeast 35 amps b.s? Am still unsure if they can be trusted ? Well i guess my question was answered in the previous comment

  • Maulana Mandalika

    How about Sony vtc6?

  • Mre92

    Sony VTC6 is a clear winner at 3000mah and 19a rated by Mooch, followed by 30Q and then HG2.
    Get yourself a VTC6 if you don’t need 20a or higher current.
    Make sure you follow Mooch on Facebook to keep yourself updated on battery safety and performance. He offers a pinned post with the lots of useful links and FAQ.

  • Jerry Mael

    Might have been handy to display the tested weight of each.

  • Eric Graves

    Has anyone tried these badboys? They’re one of the most expensive on the market… Need to know before I blow more money.

    • David Wooderson

      That’s a protected flashlight battery. Fenix makes flashlights. Long lasting for low drain flashlight application, but won’t give you the amps you need for vaping.

      Read the article above, any of those 18650’s will serve you well. Buy from liionwholesale(dot)com or imrbatteries(dot)com I am in no way affiliated with these vendors but have bought from both of them multiple times

      tl;dr that’s for flashlights, choose from list above. Duh.
