the age / # of charge cycles plays a factor as well. were both cells identical in that regard.. hard to tell because vendors could have sat on the batts for longer intervals than other cells. also, the style in which you vaped can also play a role i bet. long deep draws versus shallow short draws would likely affect battery performance when measuring. thanks for the test though.
Any experience with the 3100 mAh purple Efests?

IMO, from a business standpoint not even Efest would be dumb enough to overstate the load ratings of a battery that much, while I do agree that the battery shape does actually appear almost identical without actual information related to the battery I simply refuse to believe that Efest would not only overstate the rating by that much but ALSO change the chemistry to IMR and label it as such.
Even if they were going to use a Panasonic Cell it would make more sense to use the NCR18650A which is rated at 3100mah, not 3000mah as the NCR18650BE cell you posted is. The NCR18650A is still only rated for a max of 2C, which is only 6Amps so it would make little sense for Efest to put that battery in a wrapper labeled 20A AND IMR to boot. This is honestly all speculation, if I'm able to get my hands on some of the 3100mah Purple Efests locally from a source I trust I'll rip the wrapper off and see what's going on underneath, which still may answer nothing at all.
NCR18650A is out of the question here. Probably another 'new' cell from another maker but I am curious to know after Efest have marketed a 20A 18650 to be 35A.

Oh snap, doesn't look like a true 20A sustained, large drop @ 20A.
Nothing other than what I quoted as posted by pnyc.

I picked up one of these a couple days ago and I am definitely seeing longer lasting performance. I picked up two more today. Gonna switch out the efest 2600 in my Cana with one so I can monitor it a bit better. They hit harder than any of my VTC4's in my VapeLyfe with my Orchid @ .62 ohms, so I am impressed so far. They take freaking forever to charge, not sure if that's good or bad, lol. I plan to build a standard 1.2-1.5ohm in my Kayfun for the Cana and will report back with results. Running the Cana at 30 watts with the Orchid for sure is gonna drain any battery fast.
Panasonic NCR18650BE, an unknown chemistry battery (IMR/hybrid, but with specs and performance more like an ICR) with only a 4 amp continuous discharge rate.
Efest 3100mah 20 amp batteries: Warning - these batteries are dangerous.

I've been chain-vaping lung hits all day at .62 ohm and my purple 3100 isn't even warm...
I'm happy for you. Someone asked for info on that battery. I found what I believe to be accurate information and listed my resources. I didn't just make this stuff up.
The Panasonic NCR batteries are IMR/hybrid batteries. So its not such a stretch for Efest to call them an IMR.
Efest has been over-rating their mAh and amp limits for years. Not unlike certain "fire" batteries that we are all familiar with. We have an reputable independent facility which has bench tested these two batteries and found the purple Efest 3100mah battery to be a rewrapped Panasonic NCR18650BE.
I've seen the email response of an Efest representative lie to a customer that all Efest batteries are made by "the mother manufacturer", whatever that means. This, when we know that they rewrap Sony, LG, and Panasonic batteries and call them their own.

we have pretty much determined that the 35 amp efests are actually 20 amp continuous. i have never seen any proof that the 3100 mAh are not 20 amp. people need to go off of facts, not guesses and conjecture.
they do overrate their specs. sometimes. not all of the time. the rewrapped '35 amp' are LG HE2's, and I've seen LG's advertised as 35 amp a lot. the VTC rewraps are labeled correctly. c'mon guys. i'm not saying it's absolutely 20 amps i'm just saying we should use our brains and quit jumping to conclusions just because we've seen it said in like 12 different threads.
that just says, 'these are actually panasonic batteries'... there's no proof in that whatsoever
The link posted by Baditude shows enough proof to me. If not sufficient, how about a 3rd party independent test result:

LG never advertised the HE2 to be 35A. Their spec. is listed as 20A max. continuous discharge.

Well I've seen many sites list the LG's as 35a so idk what to tell you. I never said if you open up LG's spec sheet it says 35a continuous. I said they are advertised as 35a all the time. And that page just isn't proof, neither is a bunch of people on a thread claiming something. Again, I'm NOT saying I trust them, I'm just calling for a little critical thinking. We need to quit believing stuff just because we read it on the Internet. I know, I know... If you read it on the Internet, it must be true, right?
