Tested the Vapcell 26650 4200mah and got this:
4,474mah and 4,361mah

In comparison the Golisi 4300mah, which is a rewrap of the same YDL cell, measures:
4242mah and 4,146mah

Tested output in a Copper MF01 Mini SST-20 4000K with UCL lens at 2s:

Vapcell 4,474mah battery: got 4,410 lumens
Vapcell 4,361mah battery: got 4,480 lumens
Golisi measured 4,362 lumens

See here for past test results on the MF01 Mini

Vapcell got the best batch of the 26650 YDL cells compared to the competition, which is consistent with Mooch’s test results.

Also measured the following from my March 2020 order:

Vapcell LG M50 5000mah and got 5,044mah. The previous one I bought a year ago measured 4,964mah

Vapcell Samsung 40T Gold and got 4,262mah. I bought the same 40T from Vapcell twice (forgot the dates) and the measurmenet was 4,038 first batch, and 4,101 and 4,156mah the 2nd batch. I’m not sure if it is due to Samsung improving their process or Vapcell got lucky with a really good batch. At 4,262 mah, I would love to see a comparison between this and the Molicel P42A, which is supposed to beat the 40T when tested by Mooch a while ago.

I also bought 4 Vapcell Samung 50G that is supposed to be 15A 5000mah. These are wrapped in a gray wrapper with no description because Vapcell just received them and haven’t designed a wrapper yet. I was super excited to test these but very disappointed to find out they are recessed top like the Tesla 5000mah Facepalm and not flat top so my charger cannot charge them. The ones I receive looks nothing like the gold wrapped flat top version in the OP so I’m wondering if the ones I got are even the 50G. I hope it is a mistake because recessed tops will not work in some flashlights also and a waste of the supposedly highest current 5000mah on the market.

Recessed top… what's the point I wonder. Pictures? What metal or conductive material is the top made of? Hope it is not aluminum, but if those cells are built to “Tesla spec” then it will.

Never posted a pic on BLF and not intending to learn how to do so for the time being. Maybe Vapcell can take a few pics of the actual wrapped 50G and post it here so we know for sure how it looks like before people buy. Would suck to buy it and not be able to use it in our chargers and flashlights like in my case Sad

I charge recessed tops with small thin magnets. Been using then for years on some cells.
