I was about to grab a couple of the purple "35 amp" 650s over the holidays and actually picked up a pair of the LG's for about $2 more than a SINGLE Efest hah.
Makes sense to buy batteries branded after companies who actually make them. Iv got some older AW IMR, some Efest (red crappy ones) and some LG He2's and the LG are the best by far, 2nd place the AW IMR's, and lastly the red efest...
I've been following this thread with great interest. I'm a noob to all this and like many have purchased Purple Efest 18650 3100ah 20A from a reputable dealer in Holland after what I thought was reasonable research and am now a little concerned! I don''t have all my vaping kit yet (it's on the way) but will be using a Vicious Ant Phenom MOD with a Squape R RBA and planned to use coil builds around the 1.5ohm range (not planning to sub ohm). Am I going to be ok with this?
Also having watched the extensive videos on the Pegasus Vapor Academy about different batteries I notice he mentions the Samsung INR's as the current gold standard but when I search for them on the Samsung corporate site I can only find a reference to 18650 batteries that's dated 2008, so maybe even the blue Samsungs are not what they seem?

I would say that you made an reasonable choice, the Samsung's would be better for extremely low resistance builds but with your application the Efests should last a bit longer but not much before needing charged but for the money the Samsung's are usually much cheaper making them a good choice money wise. The Efest 3100's excell when used in a VV/VW regulated mod.

Pretty cheap price, the price of one EFest 3100

One quick thing I've noticed which is also a relief - I'm using an iPhone app for coil build calculations called MicroCoil Pro and in this app you select the battery make and model from a large database in the settings which it then uses in the various measurements. I was thinking that the calculations it does would all be wrong, assuming it just used factory specs, but I've noticed that the app shows the Battery Max Amps (Real) as being 6.4A for the 3100ma 20A Efest which would be in line with what the testers have concluded!! That's quite impressive.
Therein lies the issue with Efest. They don't put the Continuous Discharge on their wrappings, they put the pulse. Anyone buying Efest batteries needs to do a LOT of Google research before choosing one of theirs. I use the 2500mah "35A" batteries which are just rewrapped HE2's so I don't feel bad about them at all, it just took some extra work to find out what they truly were.
Sorry but I didn't read the entire thread here.
I am a noob and new Sig 100w plus owner with efest 18650 3100 mah batteries. Does this post apply to me also.
Forgive my laziness in not reading through

Most definitely. The Efest 3100mah, from what I can see are 10amp continuous discharge batterie, with a 20amp pulse. Bad Mojo on a 100W device depending on what you have on it, and how you're vaping it. Personally I'd never use a 100W device with less than 20A continuous, 30A if you're planning on pushing it to the higher wattage settings.
I own two of the Efest wrapped HE2s...perfectly fine battery. I will not be buying more of them however and wouldn't recommend them when you can get HE2s and Samsung 25Rs for less money.
I just read about this issue. I bought two Efest 18650 35A 2500 batteries. Got them in the mail yesterday. They did have an authentication sticker, but when I try to find where to type it in, there is no box to do so. I emailed them. I was surprised with a prompt response. Although there was a language gap. Then after I wasn't sure what she was saying, she said take a pic of it, and she would check for me. The response that second time was very speedy. I have not sent a photo yet, nor taken one. Why can't they just fix that on their website? If the Efest battery is not up to par, I will be unhappy. I don't have a lot of money to waste. Luckily I bought two. This was my first purchase of high drain 18650 batteries. I had planned to use them in a Panzer mech mod. I was told to get the Sony. But I needed other things, and the Efest was in stock. I wish I had seen this thread sooner.
^^^^ As long as they're authentic, they clone all the good batteries, they will serve you well.
the person you had a conversation with obviously doesn't work in their IT department
Are you suggesting that they might have more than one employee? Just kidding Senator
