Hi all,

I need your help with charging two 12V batteries (serial connection). I have two 12V 7.2Ah from FIAMM , it's lead acid battery.
So, I need max. current and max voltage for charging two batteries connected in series because I need 24V voltage. Is it charge current of max 1.5, and charge voltage of 30V o.k. for charging, or should I use greater voltage, or should I charge batteries in parallel ?

Thanks in advance,

 

I would charge them in parallel with a comercial charger.
