Samsung INR21700-50S

Thanks for the update dude. I’m still rolling with my 50E’s and 30T’s

Photos from agents

There’s no mass production yet

So it’s more appropriate to buy Samsung 50g or 48x, 40t temporarily :slight_smile:

I ordered 30th December, still not shipped. No idea when they will be either as they have not responded to my message.

Thinking of grabbing some 40T’s for my K1 and K9.3’s… prob better then my 30T’s or 50E’s.

Received my T50s this morning. They just look so sexy

Nice! Where’d you get these

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??

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/t/-/53910

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 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:

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.

Sadly the graphs are available only for the registered forum users (even though the thread is in English on a German forum).

Ooops, sorry. Merci beaucoup, thefreeman!

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. :-) 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 3x21?

Or??
