Auto cut-off battery charger:
This is an auto-cut-off battery charger diagram for a 12-volt battery. This circuit can protect the battery from overcharging. This circuit needs to be adjusted using the variable. At first, we have to fully charge the battery. After charging the battery, we have to cut off the relay using that variable. Then the circuit will work at that voltage. Like we cut off at 13 volts. When the battery reaches 13 volts, the relay will automatically cut off.
