Automatic 12V Battery Charger is used to charge 12v Battery. This charger controls the battery over charge. This charger automatically cuts off the maximum voltage of the battery when it reaches. Charges the battery when the battery is low voltage.

Nice video however it would have been more useful if the schematic had been explained. Like working principle of the circuit. This looks like a ad for PCB manufacturer.
thanks sir plz whats no. sir
Hi, I have tried to buy the board with the soldered components, and only this scheme serves to burn the battery.
Since at first the full led turns on at 9.3V and the charging one turns on at 12.8V, which does not stop charging the battery, giving an output of 22V. Burning the battery.
would you be kind enough to share a proper circuit diagram ?
Why Can’t the Author reply to Mr. Jordi comment? I also agree with Mr. Madhusoodan. Can Techsaw please explain the working of the circuit ? Looks very promising circuit.
