I could use some help getting a hold of the correct batteries. What I am powering is actually a flashlight and not an RC car but I need to be able to discharge it at around 40 amps.

I see here it appears that Lipo cells can easily be used at much higher amperage.



Here are my main questions.

1. Can lipo cells be had in 18650 size cells?

2. Can you point me to some reputable sources for them? I cant risk getting any trash for this project.

3. My original plan was just to use loos cells, but if you guys know of somewhere I can get a 4S 4P pack made from these and a charge that would work with that I might consider going that way. The cells would need to be welded long way and not side by side for the S part.

Thank you in advance.
