Hello.
I know I know I know, there was lot of said about Efest batteries but still, I have few questions.
And this is serious. I'm no intention to troll or anything. I want to get clear on this.
I'm on Moochs side in this, just to be clear.


1) Does Efest manufacturing own cells or it is simply rewraping them all?
There is one guy, vape shop owner who still claims that it is not true that Efest rewraping cells. That he does it pretty well, because did some lunches with Efest manager, talks lot with Efest managers on vape meetings and such things.
He mostly talking about that china shops/resellers doesn't sell Efest cells because Efest sells them just to Europe an US.
And he even claims that Efest manufacturing cells which are rewraped by other China companies.
It sounds ridiculous to me but I would love to get some proof which would break those statements. Lots of folks in our country are lazy to use Google or likely to believe him than "some old articles from 2014".

2) Someone once said that Efest never lied about A ratings on wrap, but just stated that numbers wroted at wrap is not continual but pulse A limit, so people confused it with continual limit. And that continual limit we should not care off, because it cannot be used in vaping devices (?).
Explanation needed.

Edit: I don't have any intention for witch hunting or doxing, so I will try to not disclose any personal info.

Efest batteries are an accident looking for a place to happen.

They list Pulse Rates of discharge as cdr (Continuous Discharge Rates)

If i HAD to use efest batteries it would NOT be a mod. Probably a flashlight.

1) They do not have a 'cell' manufacturing facility/plant/factory.
So, it would be real darn tricky to manufacture something when you don't have a facility to do so. From raw materials/components to manufacturing a functioning cell.
Lots of thing are 'lost' in translation, to some people designing labels / logo's / for battery wrap & boxes then wrapping a cell with their wrap & putting them in boxes with their name on it is manufacturing.

Proof? it has been proven beyond any shadow of any reasonable doubt repetitively.
besides the hundreds if not thousands of times an efest label has been removed and there is a clear indication of an 'actual manufacturers' cell under it. Or, been verified by way of chemical & metallurgical testing that identifies the actual source of the components & raw materials.

You're not going to change anyone's mind that is convinced they are right.
The reason some vape shops love them is if bought in bulk/wholesale they're ridiculously cheap.

2) IF a cell is labeled with an amp rate the industry standard is the continuous discharge rate.
You won’t find a newer authentic cell from an 'actual manufacturer' that prints the amp rate on a label.

Pulse, burst, instantaneous is worthless unless qualifiers accompany the rating.
amp load xx - voltage xx - voltage sag/drop xx - cell temp xx - time xx milliseconds or seconds.
Not only the above but as cells are used & age they lose capacity meaning they lose the ability to produce xx amps safely.

Bottom line if you want to use efest, go ahead, but understand they can & frequently do change which cell & quality of the cells used underneath their wrap.

I had over 20 efest cells that were in reality Samsung 25r's Just sayin... But it can always be a gamble

For lower wattage vaping, Efest batteries are fine in my application. I treat them all as 10 amp batteries and have had no problems with them. The advent of subohm and high wattage vaping brought their amperage claims/exaggeration into question, but as a more basic IMR battery they meet my needs as backups for AW.

If I were using a high wattage setup I would avoid them as there are many proven high amperage batteries from LG, Sony and Panasonic.

I haven't read of any particular accidents involving Efest batteries. Just overstated labels.

By why support a malicious company that intentionally grossly inflates the capabilities of their batteries and puts their customers in danger? Especially when Authentic Sony, Samsung and LG can be bought for at many times less than those grossly exaggerated eFest's?

Im an eFest manager!

That statement is about as authentic as their batteries. Even with the 26650 on Moochs chart he has explicitly stated that they are still rewraps, and that even though they use the same cell under the wrap, that this could change at any time and we must still be cautious in using them. Note that the 40A rating they gave the 26650 is nearly DOUBLE the 23A rating Mooch gave it?

If I could, I would boycott vendors that even carry eFest. Unfortunately its just not realistic.

Find the iJoy 26650's, they're incredible.

I do wish Sony, Samsung or LG would produce 26650's but sadly I don't think that's going to happen.

Here's the thing. Other than Sony (who has sold it's battery component to Murata) and Panasonic, pretty much everyone else gets their batteries from other manufacturers like BYD and ATL (both Chinese battery manufacturers). Samsung gets the majority of their batteries from ATL (Amperex Technology Limited). LG gets the lion share of their batteries from BYD (which, by the way, has a manufacturing facility in Shenzhen).

They're not IMRs, very few of the batteries used for vaping are. Most high drain Samsungs, Sonys, LGs etc are of a hybrid chemistry that combines the safer chemistry of IMRs with the higher capacity of ICRs.

Early on (years ago) I bought a couple of purple Efests from the local vape shop for about 50% to 100% more than I can get Sony, Samsung, and LG for from Orbtronics or RTDVapor.
I haven't pulled the wrap off the purple Efests, but they were good batteries that matched the name brands for vape time at 10W. I was lucky. That said, there are no (or very few) batteries that test out to 35A outside of 26650's.

These days those purple Efests only see use in my 5W led flashlight. And that's when my name brand batteries are charging.

    1) Efest is an electronics trading company that sells private label batteries. They are not a battery company. Every single battery they market to vapers is a rewrapped Samsung, Sony, LG, or Panasonic/Sanyo battery. Every single one performs identically and is identical in appearance to one of the Samsung, Sony, LG, or Panasonic/Sanyo batteries. This includes examination of the tooling marks with a 10x loupe.

    Efest is lying to that shop manager if they told him they don't rewrap batteries.

    Efest might have exclusive manufacturing agreements with one or more battery factories to produce for them but, if this is being done, it's only for the low-amp power bank and flashlight cells. Nothing we use.

    Efest's own marketing department told me they make some and rewrap others.


    2) Some of Efest's batteries only have one number on them with no indication whether it's continuous or pulse. "Max" is utterly useless as a rating indicator as it can mean continuous or pulse.

    If the battery only has one number on it that means you can discharge it any way you want because they have not indicated in any way that it's continuous or pulse. If they are claiming it's only a pulse rating then they are playing a bs game with us, trying to trick us into thinking it could mean continuous. That's unacceptable.

    Rating a 10A battery at 35A doesn't work even as a pulse rating. What they did. was a lie...period.

    Any company that says that a continuous rating is useless because we pulse batteries when vaping is not only ignorant of the most basic concepts regarding battery ratings but they are blatantly ignoring the safety of their customers.

    A pulse rating is useless unless you define the length of the pulse, the time between pulses, and the criteria used to establish the rating (temperature? run time? voltage sag?). None of these have ever been listed by Efest. Their ratings are useless and misleading.

    Continuous current ratings are an industry standard and the only way we can compare one battery directly against another. None of the large battery companies have pulse ratings. Why? They're useless because they would only apply to a specific application. The only timed discharge ratings the big companies have are for the protection electronics for the battery packs using that battery.

    Efest would know all this if they were a battery company.

    Continuous current ratings are also critical for safety. It's the only way you can know if you might have a problem if there is a mod malfunction or accidental button press that discharges the battery continuously. Efest saying the continuous rating isn't important shows remarkable ignorance of battery safety and their customers.
