I know what I am about to say is controversial but that is the point of a forum, right? lol, now that being out of the way I am always looking for new batteries that bring me the same joy as my now dying vtc5's (very sad) and as it has become increasingly harder to find these batteries (even from reputable vendors) I am now looking to the horizon with hope...(dramatic pause lol) I do not care what anybody says about not trusting these amp limits and the speculation of them being rewrapped (I have yet to see anyone provide a link proving what they are claiming with the rewraps) This is the list of batteries I have purchased and used all the way down to .08 ohms (no that is not a typo) without any venting, overheating, thermal runaway or severely reduced battery life as others have claimed:

MXJO yellow 35 amp 2500 mah

Purple efest 35 amp 2500 mah

Green Imren 38 amp (or 40, do not remember what was claimed) 2600 mah

I am already aware of the dangers of running that low and yes I use an ohms calculater (vapecalc.com) to do my math but I have put these batteries through hell and they perform better than my vtc5's (although keep in my they are old and dying) Purchasing these batteries and doing what I do is not recomended but hey, pushing limits is what leads to results not always playing it safe. No, I am not telling anyone else to do this and if you do, you do it at your own risk and I assume no responsibility for such actions. I just hate that no one else will test them and put out at least some results and all three of these perform rather equally and very well at sub ohming ranges.
Mxjo,purple efests,green imrens and LGs Ive pushed all these batts as well and they performed just fine. People should vape safe but think others get a little carried away with telling ppl these batteries arent safe at .09 etc builds. I personally have used these with those low builds and theyve held up just fine. Of course there will always be a safety issue when vaping at extreme low builds but thats the users choice. Even sonys have limits. These batts have continuous and pulse ratings. If you have a .08 build you wont be firing it for more then few seconds and these batts can handle 50 amp 2-3 sec pulse. If not I wouldve vented these various batts a long time ago.

My personal buying guide:
Ebay is a gamble. If using mech mods i really don't recommend rolling these dice
To make things simple, only buy Li-Mn IMR batteries from reputable manufacturers (never anything with "fire" in the name) supplied by trusted vendors

There are real physical properties that limit how/what a battery can do in terms of charge capacity and discharge rate. at 2600maH and 30A continuous discharge VTC5s are the Cadillac of batteries. Generally higher capacities are achieved by lowering discharge rate, so keep that inverse-relationship in mind when browsing around. Most manufactures list the battery's pulse discharge which is irrelevant when vaping so ignore it and find the battery's continuous discharge rate.

Keep in mind that for mechanical mods the quality of your battery is your only safety feature.

Buying cheap batteries is like buying cheap tires. At the core of your vaping experience is your battery, this is where the metaphorical rubber meets the road and considering that your batteries will be with you from one mod to the next, spending a little extra coin here goes a long way to getting the most out of your devices.

Think of your batteries and charger as an investment. Higher quality products will last longer and perform better and reduce your expenses over time as you'll find you wont have to keep replacing fried cells. Cheap chargers can actually damage batteries during charging.

Personally my rotation consists of 2xVTC5, 2x18650 and 2x18500 purple efest, and 4x26650 MNKE 30A with a Nitecore i2 and I get terrific and consistent performance

I use an purple Efest IMR 18650 - 2500Mah 3.7V, 35amp for my mech mod and this battery is great for my mechanical mod. I am running a stingray mod with a TOBH atty and dual coils of 26ga kanthal (7 wraps each coil) and this gives me 0.23 Ohms. Chuckin clouds with 100% VG juice.

Technically there is no such thing as a 100% VG juice my man, there is PG in the flavor extracts and not to mention the flavoring in the extracts and it also depends on if you are including nicotine that can be VG or PG based as well just FYI, a more realistic measurement is like a 80/20 VG heavy blend unless you just run pure VG with no flavor or nic...

Agreed and just to show it can be done...here is a link to me using a mxjo 35A without losing my face lol, I was going to do this at .07 but it came out to .08 and did not feel like starting over. I feel like people assume this is impossible but here is proof just so it is clear, once again to anyone new and watching this, DO NOT TRY THIS without getting some knowledge, experience and time under your belt...Coil building and cloud blowing is an "art" and not to be taken lightly, oh and the video quality as I found out with this video is garbage when emailed to your computer and then uploaded to you tube lol (and doing all this one handed was a challenge as well)...I take the battery out multiple times to show it is in fact an mxjo and to show it was not hot to the touch at all and I tried to keep the camera on the mod at all times to show it was in fact the same mod just in case anyone was wondering

And on a further note here is "some" of my workspace lol, alot of it is at my job (I work in a B and M)

Come on man, the calculator you reference: .08 ohm you are drawing 52.5 amps on a fresh charge. Is this going to result in an explosion the first time? Probably not, but you are stressing the hell out of that 4 battery rotation you have going there, eventually that is going to go bad. You knew it was a controversial post when you hit the button So please spare us the indignant rebuttal.

And this isn't even the real problem with this post. Someone is going to come along and read your post and think totally legit lets give it a whirl and hurt themselves. That should bother you a little. And if it doesn't no problem, but it should. You at 29 are old enough to know better.

I think a few points alot of people overlook are voltage sag under load, resistance of the rda combined with that of the mod (not to mention if you have a spring loaded firing button lol) and the fact that all of that also has to be considered into my kind of sub ohm builds...not saying that means what I do is perfectly safe, just saying it is not as dangerous as some people who have never even attempted these builds would make it out to be. There is a difference in knowing what you are doing, choosing your mods carefully to know they can handle what you push through them and then being an ignorant teenager attempting to win cloud comps by making such radical builds they must use a vape towel just to hold it while using it (these are also the same kids rolling around blowing huge clouds obnoxiously in public places making vapors everywhere look bad) I work in the vaping industry (not high profile, no claim to fame here) and it is my job to educate customers on the dangers and give knowledgeable information, anything I say has been backed up by doing it and NONE of my mods are hot or barely even warm to the touch after use. This kind of knowledge comes with time and is not taken lightly and anyone who does so is choosing to drive 100mph with no seat belt, that is their choice and if no one told them it was safer with a seat belt (no one has common sense these days lol) then how can you bash them for it? Just saying...

True enough, I guess I should have said my nic is 100mg in 100% vg flavourless base. The only PG is in the flavouring so it would work out to be 80vg/20pg. Thanks for the correction my man but this is the closest you can get other than vaping 100%VG with 100%VG flavourless base and no flavour extractadded.

I just bought 2 orbitonic 3400mAh 18650s and a Nitecore i4 intellicharger 2nd gen... So how did I do?
Those aren't high discharge, and while they are hybrid cells they're more towards unsafe ICR chemistry than safer IMR chemistry. Not the best choice for mechs (or even lower wattage regulated mods).
