If you have any vape shops near you, the vape batteries tend to be about as good as LiIons get

Lion wholesale gets recomended a lot but I typically buy from ebay.



Last testing I read about the ( KeepPower ) brand was one of the best but also cost more.

I buy from Lion wholesale, they are fast, at a great price, and guaranteed genuine brand name...

I have bought many batteries from liionwholesale. When you do it is best to buy all you can as the shipping costs are about the same for 1 or 2 as for several.

BTW does anyone have info about what 26650 battery is the safest in case there is a short curcuit in my torch or laser? What means it would cut-off if current surpasses 10 or 20 A.

Most of people in forums is looking for fast charging, higher capacity, higher discharge current... but for me all these numbers are fine on all of the batteries since years - the only thing I do not clearly understand is how the PCB in different protected batteries works. Does it react on the voltage drop or current raise to a special value?

I had several 18650 and 26650 purchased with torches and now I tested them on a programmable load in constant current mode.

For example Sanyo 18650 which came with Astrolux torch cut off when voltage drops to 3V (this happens at currents in range 5-6A)
Trustfire 26650 came with a big torch from ali and cut off bw 7-8A (looks like PCB reacts at current, not at voltage drop)
Litwod 26650 from ali (rechargeable battery with PCB is written on it) does not stop at all even if I raise discharge current to 20A. Is it protected or really not???
More expensive Keeppower from ali claimed in specs to be PROTECTED (IC made in Japan) and to have cut off at 2.75V - this one looks the most dangerous! I raised CC to 20A and the voltage dropped to 2V and it kept on discharging - no cut-off at all.

Can anyone recommend me a short curcuit-safe battery?
