Hi, after several hour of googling, I did not find anything suitable (most likely wrong keywords or I am just a noob). There are many charging circuits for Lipo batteries, but almost nothing for LiFePO4 .
Basically, I have this 3 cell battery that I need charger for. If I understand correctly then I have to charge each cell individually with constant current until it reaches 3.65V and then continue with constant voltage of 3.65V.
I found several circuits using LM317, but all of them where designed to charge single cell. Where as some ICs are designed for all 3 cells in series.
So do I have to charge each individual cell or can I just charge them in series? Is there any simple charging circuit that I have not found yet? Btw I would like to use general AC-DC wall plug converter to power up the charging circuit.
Thank a lot.
