I need a good 5000 mAh 21700 cell for my K9.3 lights, but cannot find either the Vapcell T50 or Samsung 50S.

Anyone got a link to an online store with some kind of supply??

(Send help, I've bought too many Emisar lights)

Ya me too Helio! My 30T’s put out some nice power but run out sooo fast!

Can’t someone just make a 5000 mah cell with the power of a 30T? Maybe graphene batteries in the future?

T50's are the real thing. Being Samsung gave them the "S" marker, it seems appropriate - same class as the 25S, slightly lower than the 30T and 40T.

 Need to ping Dennis again on availability: https://budgetlightforum.com/node/63450

Anyone know what cells Acebeam uses in their IMR21700NP-510A’s which are rated 5100 mAh and 20A? Souped-up 50S’s?

Do you mean the Samsung 25R? That would mean the 50S are even one step further towards high current, between the 25R and the 30T/40T.
The Samsung 50S are rated 20A, right? Because there is a new LG cell, INR21700H50, 5000 mAh, which seems to be rated at 25A. I would expect similar performance as the Samsung 50S.

edit: Sorry Tom, I just found out that there is indeed a Samsung INR18650-25S cell.

At least in this video they seem to be LG M50, which isn’t even funny anymore. High drain, my ass! 5000 mAh, 7.275A Maximum Continuous with 60 °C cutoff!

Those scammers! I was always wondering what it was. Got one with H30, but would never buy them cos price is way too high and after seeing that video, just wow.

Those look awesome dude! So beginner question… so does the “ INR 21700 T50 5000mah 20A” put out as much power as the 30T?

Reason I ask is I have an Emisar K1 with the SBT90.2 5700K, 4500lm and it needs tons of juice to reach its full potential

And generally the Vapcell batteries are good? I saw some 26350s there that look wicked too

Thanks!

toobadorz published some great information with discharge curves on TLF:

https://www.taschenlampen-forum.de/threads/21700-comparison-constant-current-power-and-flashlights.79436/

Maybe it can also be found somewhere here on BLF. I didn’t check yet.

 

To answer your questions with my personal opinion:

  • Samsung‘s 50S or Vapcell’s T50 outperforms any other battery (even 30T and 40T) unless you are a „lumen hunter“ who strives to get the maximum turn-on lumens of FET lights in the first 1-5 seconds on Turbo. In that case, better use the 30T.
  • It is probably the best compromise in terms of high current sustainability and runtime.
  • The Noctigon K1 SBT90.2 probably uses 19-22A peak current - the 50S/T50 can handle this current pretty well.
  • Vapcell has got a good reputation for selling quality cells rewrapped in their own shrink wrap. IIRC, the T50 was tested by Tom E and toobadorz and both members were pretty satisfied with the performance results. Hopefully, HKJ will soon chime in with his review.

Hey Lux, didn’t know you were on this thread!

thanks for taking the time to type all that! So I think I might replace all my 21700 cells with 50S’s, unless… there is an even better 21700 coming out soon?

The T50 sounds like a great fit for my Noctigon 9.3s too

Isn’t it amazing how this technology is progressing? I still remember when NiMh rechargeables came out and being so amazed by not having to buy new batteries every time one was dead

Anytime, Photon Master. Smile I don’t expect to see anything better in terms of high drain than Samsung’s 50S anytime soon. It’s more likely that competitors catch up with its great performance. Maybe Molicel can at some point release a P50A, who knows. I wonder why LG Chemicals, Murata/Sony as well as Sanyo/Panasonic do not offer any real competition here.

Hopefully, there will be some progress in capacity, though. If they somehow managed to squeeze 6000 or 7000mAh out of a 21700 cell, wouldn’t that be awesome, too? 

For now, I do NOT recommend buying the 50S in large amounts for it is way too expensive. I paid about $ 12 for one battery only. For comparison, NKON sells the 30T for € 3.45 per each.

https://eu.nkon.nl/rechargeable/li-ion/21700-20700-size/samsung-inr21700-30t-3000mah-35a.html

As soon as supply of the 50S gets better, prices should settle at less than $ 8.00.

I’m patiently awaiting more testing (HKJ?), availability, and significant price drop.

Until then I’ll suffer through with 40T cells.

I still have a handful that are looking for the next irresistible 21700 light.

Could it be the new Jaxman M3?

Or Simon’s upcoming 3×21?

Or??

My review of the new T50, the language is Russian, but I hope the charts will tell a lot.
I also have a lot of reviews on my personal blog

They have a newer version of that cell and it’s quite good for a protected battery.l with USB charging.

Thanks Lux so tempting (: I have six 30T’s and three 50S’s which are good for my 9.3 home lights. I have my 2000K E21A running for hours a day.

So I bought a Graphene power bank a few months ago and it’s rather amazing. It holds 20,000 mah and recharges from zero to 100% in like 45 minutes. It outputs 100 watts which is enough to run my HP laptop

I wonder what kind of cells it has inside …

Hi! As I’ve mentioned earlier in this thread, LG has the INR21700H50, 5000 mAh, which is rated at 25A, according to Vapcell’s Facebook account.

Hi! How do you know? Do you have a link or something?

I mean the cell inside that Acebeam battery, in the video I posted, is a M50 which is also a quite good cell. So maybe, probably, it isn’t too bad for a protected battery with USB charging, but it’s neither a 5100 mAh nor a 20A cell.

Most of us know that some crap-fire batteries marketed as 10 000 mAh should be avoided. Acebeam, Nitecore and the likes do not offer crappy batteries like that, but this is just another example of them not really being trustworthy and I hate that.

Haha yeah. My buddy asked for advice on getting a flashlight (don’t you love that?) and after I have him some ideas (i.e. Emisar D18), he sends this link for a little 90,000 lumen flashlight from Amazon for $20

Meanwhile I went out for a walk with my Imalent MS18 tonight and the thing is massive and… $600

I had an interesting talk with Vapcell yesterday. It seems Vapcell is one (or maybe even the one and only) exclusive reseller of this powerful Samsung 50S battery. Samsung is apparently forbidding direct distribution of its 50S battery, i.e. it will probably not appear as bare battery like 30T or 40T in known battery retailer shops. Sad Since all Samsung batteries can be traced back by their serial number it would be a bad idea for a retailer to illegally sell the naked battery to customers, facing severe consequences in their business relationship. Let's hope Samsung will change their mind eventually.

I also hoped LG Chemicals new H50 battery to be a direct competitor to Samsung's 50S battery. According to Vapcell the H50 turned out to be as good as Samsung's 50G but not as good as the 50S. (picture borrowed from mysku.ru)

Yeah but I mean, Vapcell is obviously biased toward themselves. IFAIK Samsung and others have always forbidden direct sale of cells, but maybe they put more effort into preventing that since the LG exploding cells thing early 2020. I noticed that recently Nkon added the 50G and they are not with the original wrap (yet are sold and appear as new), they probably had to find alternative sources for them (when I contacted them in September they couldn’t find any source for them), hopefully the will be able to find alternative source for the 50S too.

I predict that given time, these cells will be widely distributed… that is my hope anyway.

Could do a group buy. I’m sure 100+ pieces would be snapped up.
