Purple efests

[VaperCaper]

VTCs are much better.

Some of the rewrapped purple EFests *are* Sony VTC cells.


You can go back and forth on which batteries are better. It's a little like Apple vs Windows.


The thing to remember when you are comparing EFest and Sony VTC batteries is that both of them are mid priced batteries at about £5 a battery.

If you want the best batteries you need to spend more than double that.

I'd suggest AW batteries or the top end Samsung or Panasonic batteries are the best around. You're looking at about £12 a battery for those.


both EFest and Sony have their minus points.

Sony stopped making VTC cells several years ago, and they do not make them for consumer use. They are all intended for use in laptop battery packs etc etc and sold to suppliers. Some suppliers have been repackaging them and selling them to vapers (and also presumably torch enthusiasts or other people that use lithium 18650 batteries)

EFest have started putting the pulse ratings on the wrappers not the continuous discharge ratings on them. All of the EFest cells are rewrapped, though that's not a bad thing in and of itself. (AW cells are rewrapped and they are top drawer)


all of these batteries are what they are. Reasonable value batteries at a reasonable price that will do plenty well enough at 0.5ohm+ If you intend to push them harder than that then you should consider much more specialist batteries (at a much more specialist price)

I'm not a battery expert, talk to people like gords1001 or Torchy for a more expert opinion.

Some conflicting views on this.

I have 10 VTC4s from 3 different suppliers and they all charge in the same time within 3 mins of each other, they all get rejected from the DNA30 within a few mV of each other and all measure similar internal resistance. I have tested the VTC4 and the Panasonic CGR18650CH over 113 charge/discharge cycles and both are extremely consistent. I also have 9 Red Efest 18350 from 3 suppliers and they don't match at all between batches and one batch had a very poor life span and this was from the most reputable of the suppliers.

IIRC it was only the first Efest Purple 18650 2100 mAh 30 A that was a Sony and correctly quoted the discharge rating on the wrapper. I am appalled that they just put the pluse rating on their wrappers and at any vendor who doesn't clearly state this the case. It is potentially dangerous and lots of people seem to think the Efest purple 2500 mAh 35 A is comparable to the VTC5 that has almost twice the current providing ability.

I have 14 Panasonics, great batteries, but not very high drain, the only Samsungs I have are ICR so don't get uses at all.

As far as I'm aware at the moment there is not a better 18650 for very high drain applications than the VTCs, certainly not AW (great quality). Their quality is on par with Panasonic and better than Samsung, way better than Efest & LG IMO.

Just to throw in some conversation/shock value, I read a lot of people saying that they run crazy 0.02 ohm builds on purple Efests with no problems. A good portion of these people are also very strict about keeping their pulls to a maximum of about four seconds and many of them only keep them for 60 days before disposing of them. Some of them have own cloud chasing competitions with these cells and a yet smaller portion of them are well respected within their online communities.

Are they playing with fire? Well, it's up to everyone to decide. The whole concept of using these types of cells to fire coils is ill-advised by the manufacturers themselves so if you use an 18650 to power your mech or box mod, you're technically part of the problem.

I'm no expert by any stretch. I read what I can on battery safety and venting incidents. So far, every vent I've heard of has come around due to mechs firing well in excess of the length of time it would take someone to inhale a huge pull. Am I telling you that this anecdotal evidence this makes the hobby safe? Absolutely not. I fully respect anyone's limits in terms of batteries and amps. What I AM saying is that you pays your money and takes your choice. A LOT of battery safety is about having experience and respect for the process of discharging a battery at a high discharge rate.

And of course, you get people who couldn't spell 'safety'. Again, I'm just throwing this in for the sake of conversation.

So what would you suggest is THE best / safest option to use with a mech? Assuming we're not going stupid low ohms?


Having only used low power regulated mods im not in any position to agree/disagree with this thread but would like to know more on mechs and batts

The most popular answer to that question would be the Sony VTC4 or VTC5. After that? You know as much as me, mate. What I'm beginning to gather, though, is that most of the more popular battery makes and types are also 'safe', so long as you know what you're doing. I'd like to qualify this statement by stressing that I'm only gathering this opinion strictly by anecdotal evidence and would never cite it as the absolute truth.

For me, the long-and-short if it is that if you just want to vape to keep off the fags, then stick to a tank with a regulated mod. You'll have a long and very pleasurable experience for years. Sub-ohming and super-sub-ohming are more in the hobbyist sector of vaping. It's very high maintenance and requires a good understanding of how everything works. This side of vaping lends itself to loads of tinkering, tweaking, adjusting and general fussing over your equipment. If the sound of this doesn't pique your interest, you're probably not going to get anything from it.

This is strictly all in my opinion so please do take it with a pinch of salt.

I've not read the whole thread sorry, but samsung inr cells hold their voltage under sensible sub ohm loads .16 - .25 ohm better than sonys in my experience.

In short, they hit harder lol.

There is a reason samsungs are chosen over sonys in power tool (high drain long run time) applications. I'm also aware of opinions that samsungs are rather conservatively rated in their discharge rates. I've certainly heard of a few people choosing them over sonys for .04ohm builds, but you take your chances at that.

I'm really not a fan of efests at the moment, and keeppower are sadly following the same route, you might look at seibille for honest current ratings, though there are not many suppliers as yet, I hope to see that improve.

Personal opinion, if you insist on a round cell mech mod, for me samsungs are the best for all but the most insane sub ohm builds. But if you really want high wattage, I would totally forget about round cells, brush up on your soldering work, and start looking at lipo packs. Round cells are extremely limiting in output and sag horrendously under heavy loads, there are better, safer solutions available.

Just get used to your rda's top cap looking like a fucking cullinder

Been thinking of trying new batteries, pretty new to all this so when I bought mine I just went for the highest mah which if I remember was 3200. I'm using ncr18650b think they're Panasonic. So as the dual coils in my taifun take at least 6 secs to glow hot I'm thinking I need higher amp battery as its not a sub ohm I'm using .23 dual coil which comes out at 1.3ohms. After bit of googling came across this battery test review on pbusardo's site, maybe some of you will find some info useful.

I also require info,
I'm using purple efest butthe 30a 2100mah, I can only find info on the 2250mah
Also earlier on this thread it says always enter 4.2v on calculator, why? My batteries are 3.7

Cos that's the maximum fully charged voltage. 3.7 is nominal voltage.
