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.

TomE mentioned his actual measurements here

Quote:

K1: 24 amps on a T50

and

K1: 23.6 amps on a 40T @4.21V

Same here. If the real deal and a GB is a go, count me in for 10 pcs as well.

I’d chip in for 10 as well.

Just sent an email to EVVA Tech regarding the possibility of lowering the MOQ to 50pcs. And if set at 100pcs (or 50pcs), the total cost including shipping to Los Angeles. Let’s see what they say…

I measure the discharge capacity of the Vapcell T50 and it is super impressive at 5120, 5101, 5021, 5214mah !

I hope they do sell them. We do have to verify that they’re genuine though. Perhaps someone at illumn might be willing to do so, or HJK.

Exactly. The actual hope is that a shop such as Illumn is willing to take notice and help push this along. I am merely fishing for ballpark cost. And maybe a sample pair Smile

Vapcell is selling them. The price is quite high but at least there’s the assurance of legitimacy. https://www.alibaba.com/product-detail/Newest-product-Vapcell-T50-INR217...

I only see an option to order 50 of them…

Ahh… “buy samples”. I wonder how long they’d take to get to USA?

This page offers two at a time: https://www.alibaba.com/product-detail/vapcell-INR21700-T50-5000mah-20a-...

Shipping is a killer though.

Yeah…Nope…You can place an order, but Vapcell CS on Alibaba will inform you that the T50 is out of stock and suggest the 50G as an alternative.

That’s too bad. I don’t know how alibaba will respond if you as a buyer claim goods are counterfeit so it’s a risk to buy 100 50S cells from an unknown seller. They could be fakes and we might not have any retribution.

I would be in for 10 if you do a group buy.

Yup, just tried ordering 10 and it denied my payment options each time.

These cells have proven to be elusive so far.

What does temperature cut mean?

I think the tests stop when that temperature is reached. You shouldn’t go over that temperature during a normal discharge.
