Vapcell LiIon batteries in 16650 size.

The batteries tracks nicely, but voltage and capacity drops a at higher current.


Usually 16650/17650 cells are based on a 4.35V Sanyo cells, but not these cells and they can deliver considerable more current.

Thank you very much for this review HKJ!
I guess I’ll have some use for it :wink:

BTW, am I right saying that the major difference will be above 3A, where this Vapcell stands out?

Thx HKJ.

these are new gen 16650 indeed.

Thanks for the review, HKJ.

Are there any lights that user this battery? I don’t understand what is it for.

I use 16650s in my mix of On The Road M1 (tail) and i3 (head). Perfect fit!
Also, there is a light that I will have to have one day, juts because, which is the Foursevens Quark QK16L MKIII, made by Jason from Prometheus lights.

No, it is made in China.

Well, but the company is now run by him :smiley: I know he does (at least projects) the Prometheus. I was not aware of the producing place, so thanks for the indication :wink:

Thanks HKJ :wink:

Diameter match one CR123, length matches two CR123, this means dual CR123 light that can work at a lower voltage.
