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.

Dennis - are you guys considering offering a 20350, or better still, a 21350 cell? Need a couple and only iJoy seems to have the 20350, all sources out of stock. The 21350 doesn't seem to exist but would fit an Amutorch E3S perfectly.

Ordered a pair of the T50 21700's! They look like the best performing 5000 mAh 21700 cell around.

Who makes the T50? Seems like an amazing cell.

Nomenclature might suggest a Samsung 50T. That’d be a shock to me but a welcome one.

Thank you very much for your advice

We’re also looking at 20350 batteries

Let me ask you what are the main uses of this battery? 21350 battery?Is there any equipment available for use

It seems that the market use is not big, if you go to order, there will be a lot of inventory pressure

Thanks

It’s the chicken or the egg kind of problem.
AFAIK there are 0 flashlights on the market designed for 20350 or 21350 cells because the cells are not readily available.
There are some 26350 that would be compatible. 20350 or 21350 cell may actually make sense in such light as long as it’s modern chemistry because the 26350 we’ve seen to date are underwhelming, especially when it comes to internal resistance.
Anyway, as of now you’ll sell very few cells.
Unless we manage to convince some 21700 light maker to introduce a shorty tube.

I believe that this cell format has as much potential as 18350. But for this to happen someone would have to go first – or 2 parties would have to go together.

Maybe some BLFer who has contacts with flashlight makers could talk to them about that?

EDIT:
I see that I actually forgot about 1 20350 light. Smile

There is a fairly popular (in some circles...) light from Amutorch called the E3S, usually top item featured on their home page here. It's a triple compact light.

They can provide a 20350, so one does exist. However it can fit a 21350 - I know because I can remove the tailcap and insert a 21700 in with no problem.

So actually the E3S is a 21350 light with no battery in existence that fits. Instead a 20350 or 18350 can be used, or even a 16340 will probably work.

I got 3 of them: copper colored, purple, and blue.

It took a while for the 18350 to become popular but now it is. I believe (or hope) the same thing will happen with the 21350 based on the ever growing popularity of the 21700.

For example, Amutorch took their E3 light (21700 based) and cut the tube down to make the E3S - only likely other manufacturers will do the same thing going forward, since the 21700 is really the new 18650. Makes sense?

vapcell Dennis, I do have some contacts to flashlight manufacturers. Maybe we can share some thoughts to see what's feasible in terms of bulk size, prices and scheduled time? Smile

I see a lot of potential for using (high drain) 21350 batteries in some flashlights that already exist in 21700 size but also for ultracompact small-sized new flashlights.

Thank you very much. If there are battery sizes with market potential, we expect to develop these products and try to achieve the best performance

We have sent samples to HKJ for testing

Mooch will not test the T50 for the time being, saying that few people have asked to test the battery

Hello Dennis,

It seems, that for some reason, 21700 T50 batteries are gone unavailable in the Vapcell AE store.

Can you tell me, what happened to them? Stock shortage, or other reasons?

Ah, good, so it is just temporary Smile

I was a bit afraid, that they would become unavailable in the same way, as keeppower 6000mAh (the only large protruding top high current 26650 battery).

Did a reseller buy a large quantity? Hoping these aren’t like the H10 14500s and unavailable for a long time.

The pair of T50's arrived today! They look worthy, I'll see how they stack up against the rest.

OK, the T50's are for real. They will replace my 40T's. They tested at start in the neighborhood of 40T's. Measured 24 amps on a slightly modded K1 SBT90.2, and 17.5 amps on a FT03 XHP50.2 with spring bypasses (GOLISI at 16.3 amps). Tested on a FT03 SST-40 at 9.35 amps, where the 40T tested 9.4 amps, and the 30T at 9.5 amps.

Nice! Big Smile

Did you use a clamp meter to check? Would the T50 heat up quickly @ 24 A?
