Hi All,

I have four identical 18650 Li-ion batteries 3.7v \ 2500mAh and a BMS 2S.
My goal is to get 5v (with step down) and more current capacity. so I though of connecting the batteries as 2P2S as battery university suggested.
2P because the Li-ion will balance themselves and for more capacity
2S for getting more voltage

Is it correct \ safe to say that the BMS will treat each 2P as one cell? and make a good protection from over\under voltage?

Thanks :)

The question is how much current it provides. For a single 18650, that would be about 1-2 A.

Does the BMS have a settable charge current?
