Hello friends, in today's video i have shown how to make a simple automatic battery charger circuit with auto cut-off facility. You can use it for any battery. You have to just set the threshold voltage as per your battery.
Normally the relay is OFF and battery charged but when battery voltage increases to the selected voltage the relay energized by the transistor which now disconnect the battery from the charger thus it prevents from over charging.
