Efest may not be as shady as everyone thinks.

[windxrunner]

From Kidney Puncher about the LG 18650HE2, commonly believed the be the cell inside of the purple Efest "35A" batteries:

"Please note: We have the offical internal test data from LG showing this battery handling a continous 35 amp discharge load. We are waiting to get permission to publish the graph / test data and also clarification on why they chose to rate the "Max Continuous Discharge Current" as only 20 amps when their tests show the batteries handling 35 amps.

We also plan to send a couple of these batteries to a well regarded battery reviewer who will perform his own tests on them.


That said, The manufacturer has stated that this is a "20 amp battery" and you should treat it as such until you have information that proves it can handle more."

Interesting.

Wonder if the battery reviewer is Tom from CPF.

They probably underrate their batteries for liability issues...

Everyone I personally know who sub-ohms uses the purple efests, and not a single one has had an issue. One friend builds down to .2 ohms and he's never had a problem.

I love 'em and am convinced that the superior vape I get from my VTC5s is purely placeboic.

 

[stanthemanchan]

Well at 0.2 ohms it's putting out around 20A @ 4V so that should be within the limits of the battery regardless.

True, but I think most of us like a little cushion.

My Efests certainly work better than my fake Sonys. And last longer. They might even last longer than the authentic Sonys. I like them.

 

[TorontoOntario]

I like authentic VTC5s way better.

Eh honestly a battery is a battery when it comes down to .2 .18 where I build, I always recharge at 3.6-3.7 and I know when to put the damn mod down and vape on another setup for a while, LG HE2, 25R, VTCX, can handle high loads it all depends on the temperature you let the battery get to. if you build low, have several setups that you want to vape on and only let the tube get warm then let it cool off. Its all about cooling, just don't let the battery get HOT and you're fine. Of course I'm not saying its safe or that you SHOULD do what I do its just common sense, HEAT = BAD

cant wait to find out..........

this is startin to sound like the whole suicide bunny deal tho.........

Well I never bought into the whole "Efest batteries are inferior batteries" thing. There's been this big stink about them calling them 35 amp bats for a while now and I've been trying to tell people that 35 amps is a good number for LG's. It's just cool that there may be some solid proof to back that up, from LG no less. I've always been a fan of Efest, and I think they get a bad rap. People pretend like they know things about their cells for sure when it's all really conjecture. I realize that I haven't turned up any hard evidence to the contrary, but it still felt good to read that bit I posted. I'm not like an Efest fanboy, I just don't think they deserve to be treated like they are a bad company who's cells are likely to explode, they know this and all they want to do is profit off others stupidity and misfortune, and that's how I see them portrayed at times on these Internet forums.

 

[BoostedClouds]

I've done .1 builds and had no problems at all. The battery doesn't get hot at all

I think the words already used about the purple efests by a well respected battery reviewer were, "This is a very high current battery, but the 35A rating might be a bit optimistic."

He also said, "[sic] Usual a battery with unspecified cell will not get better rating than acceptable, but there is no doubt this is a very good cell that is used here."

It is a 20 amp batt and any activities performed using this batt should be done knowing it is indeed a 20 amp batt.

Me as well. I have used my purple Efest 35A's up to 35 amps and they did fine, plus got better mAh than Sony's do at that current. Sony's really aren't even that great at high amps. The mAh suffers terribly compared to Samsung 25R and LG HE2.

Now I'm not a soapbox preachin' safety guy. But I felt the need to stop and say that this "opinion" goes against pretty much everything I've ever read about how batteries work, how they get damaged, and how to avoid vaping on a set of batteries that you've slow roasted into a chemical game of russian roulette. It is in complete agreement tho, with standard theory on how to beat another mile out of a dying horse.

I haven't tried the purple Efest...yet. But I do use the red Efest batts because I don't build coils that low and they work fine for my use. I also use an Efest LUC 4 charger. I don't have any complaints. I like Efest. And I'm thankful to windxrunner for posting this info. Makes me want to try the purple ones even more.

In Stock genuine high discharge rate rechargeable cylindrical 18650 Li-Ion batteries Sony, LG, Samsung from PowerStream; authentic 18650HE2, US18650VCT4, US18650VCT5, VTC4, VTC5, INR18650-25R with battery data sheet and discharge curves

Read the First asterisk
*Maximum discharge current is somewhat arbitrary, you can always get more amps if you can accept more voltage sag and don't let the battery get too hot. The current we list here is the highest that the manufacturer (LG, Samsung or Sony) supplies discharge curves for. Look at the charts listed below to see the voltage drop and temperature rise.

Buy batteries from trusted sources regardless of how much you pay.
or do what you want.

I'm happy with my purple 18650, so much so that I ordered a few purple 18350's.

As long as you're educated enough to know the difference between pulse and continuous rates, and leave room for error/spikes they're pretty satisfactory batteries.

The purple Efest 18350's are my favorites. Can sub ohm on em if you don't mind like absolutely zero battery life lol, but it can be done. But they're decent little bats.
