Balance charging li-ion ?
So I bought a replacement battery for a project. I tore down all the casing and got 6 18650. But I want to charge those batteries using the same protection circuit that was inside the casing using laptop battery adapter. Can someone tell me what are the terminal should i connect and how i connect? So far i found using multimeter that P-, P- is negative and P+, P+ is positive and there is no switch. The voltage can be checked directly.
The circuit and battery is from Dell 1525.
