Automatic Batttery Charger Circuit Needed

[Akbar]

HI I HAVE FOUR BATTERY LET SAY B1 B2 B3 B4. I NEED IT TO CHARGE ONE BY ONE.IS IT POSSIBLE TO MAKE A CHARGER AUTOMATICALLY CUT OFF B1 WHEN FULLY CHARGED AND CHARGE B2 AFTER B2 GO FOR B3 AFTER IT B4,
IS IT POSSIBLE TO AUTO CUTOFF IN SERIES CONECTION ?

 

[BobK]

Of course it is possible. But if you are going to go to all that trouble, why not make one that can charge all 4 at the same time?

can you provide me a 48 v circuit with overcharging protecion(auto cutoff)

 

[BobK]

You don't necessarily have to charge them in series, in fact, this requires extra circuitry as well.

I assume that you are talking about 12V lead acid batteries, then.

What capacity and what charging current?
