Plz tell any other equivalent transistor name except D882??

[@ashrafulalom8682]

Is it auto cut support?
You should set a full charge indicator too

OK,,,,,,,

👍🇮🇪💚🙏🏻 thanks my friend
You should add a relay with a cut off when it reaches 4.2 volts. I know you can add that to this circuit Iv seen you make those relay cut off for charging batteries before.
THIS WOULD BE AN AWESOME LITTLE CIRCUIT WITH THAT FEATURE ON IT BECAUSE YOU CAN JUST PLUG IT IN AND NOT WORRIE ABOUT IT OVER CHARGING. IM GOING TO USE THIS CIRCUIT AND THE RELAY CUT OFF ADDED TO IT.
THANK YOU FRIEND I ALWAYS ENJOY YOU VIDEOS 👍🇮🇪💚🙏🏻🙏🏻🙏🏻
