Well, thanks for posting a relatively brief and to-the-point vid showing the unwrapping. Still, the marks on the cell itself don't tell me much, not being that big of a battery junkie - does this prove/disprove the "rewrapped Samsung" story, or just illustrate the sacrifice of a new battery to some sort of electronic music backdrop?

OB I agree. I was kind of hoping for a efest stamp of some sort but it was bare.

They're supposedly LG HE2s..

All the pictures and videos I have seen that are the HE2s have the LG stamp on the barrel of the battery. This particular battery did not. I got it on vapordna to see if maybe those are "clones"
As you know, Efest doesn't make batteries. Their batts are made by various manufacturers and either wrapped for Efest or they re-wrap them. Efest doesn't say who makes them so they can change manufacturers at will and without notice.
So what might your battery be a clone of? And how do we know the battery you show after the 'unveiling' is the original battery?

At this point in the game I had hoped this efest stuff would be a thing of the past....
My requirements of a battery are to provide a good discharge of current and to not explode or erupt in flames. And, efest, lg, Samsung, and Sony batteries all fit the bill for me. I've used them all for months some close to a year without a single battery related issue. My mnkes could be better but haven't failed and work great in regulated mods.

These efest 2500mAh don't look like HE2's anymore. I unwrapped a couple here bought direct from Efest a week ago and they're all actually completely unmarked. HE2's are not unmarked, they have a few lot numbers, etc on them. Yours have one or two small marks on them that my batch doesn't. No big name battery I have matches the bare cell like this. It does seem like efest may be manufacturing their own cells now (or more likely contracting chinese cells that aren't as well known to their specs).
On your site I notice all of your batteries are marked "genuine & tested" with the exception of the Efest - is that because you haven't tested them, because they don't test out to the claimed 35A, or because you don't feel the word "genuine" would apply to these cells?
Hm, good catch. Mostly it's because we buy the Efests directly from Efest as one of their main distributors so we're not concerned with testing for authenticity. We do some testing on them to see how they stack up but they're not nearly tested to the same extent as the batteries that are impossible to buy direct. We probably should put "Genuine" though, that's a good point.
As for whether they test out to 35A...that's a matter of opinion. You can run them at 35A and they seem safe at least under normal conditions, but at the same time they perform really horribly at that high amperage, and for sure it's got less safety margin as a rating from one of the big manufacturers.
Hopefully that answers your question
To some extent yes, in other ways no. I guess since it's straight from Efest you could call it "genuine," and if by "tested" you mean you've verified that it's genuine, your explanation makes sense. What I (and I think everyone else in the Efest conspiracy club) wants to know is whether these batteries are superior to a HE2 in the way you'd expect a 35A battery to outperform a 20A battery, or should they be considered comparable to the LG and Samsung cells that they share the market with?
The positive connection of the purple Efest 35A no longer appear the same as on the LG HE2's. Combine that with the apparent lack of print identification, and maybe they no longer are. I'll stick to my LGs until a better option comes along. I have a few VTC5's, but I've never even built low enough to need them. I feel like somebody has to put another 30A continuous battery out soon enough. It can't be that complicated.
I would go by 20A at best, and since LGs and Samsungs are readily available, usually cheaper, I'd use those. Just my opinion, I see both sides of it, but I think Efest is kinda shady due to some of the business practices they've engaged in with false claims, some of which were very significant.
Thanks for the clarification. Yeah as vendor all we can do is verify they're genuine which is what we mean by tested.
I have mentioned before in other threads we have a blog-style website in the works to communicate the vast amounts of battery test data we have and condense it into reviews but we're still working towards that. I do have some data that we tested on the efest 2500mAh a few months ago that says it's similar to an HE2 or maybe just a slight bit worse but I should have those tests rerun since I can't be sure it was the same cell underneath as it is now. At this time I would consider it a competitor to the HE2 and 20A batteries until further data is tested. I'll put that near the top of the test list and try to get it done within a week or so and post back here.
That's cool man, I'll be interested to see if they changed things up, from whatever they were in the first place. Thanks.
Thanks for the hardwork. We all appreciate it.
@TBCAmor and @Jon@LiionWholesale - thanks - this is the assumption I've been going with, just wanted to make the clarification that nothing's changed that we know of...

I actually just noticed this yesterday when I happened to look at my HE2s while the blinds were open and they were in direct sunlight! There's quite a few things stamped in various places I could see through the wrapper. Its funny cause I numbered them 1 and 2 when I got them, and each one has a single stamp under the wrapper that matches my numbering he he.
