[kg300]

Hello everyone,

I have a Led-acid Battery with 50-Amp and 12-Volt. Can anyone tell me the circuit diagram to charge this battery. it's best if it is Automatic, i mean when battery fully charged it automatically cut-off power.

I shell be very thankful.

Instead of liner transformer you can use SMPS power supply, then a battery charge management IC.
