Hi
I have 3 x 12V SLA batteries connected in series as shown.
The current drawn by Circuit A is 25mA and the Circuit B draws about 100mA.
The batteries are to be fixed inside the casing. The battery A will have different discharge status than B and C.
So, how should the battery charging circuit be designed?
1) A+B+C => 36V charger circuit
2) B+C separately and A separately => 24V charger circuit and 12V charger circuit
3) All three batteries separately => 3 x 12V charger circuits
Thanks for the help.
