Review on 36V 30A Lithium Battery Protection Board, BMS Charger Module with Cable for Electric Car, Skateboard, Inverter, and More by Troy Boren

So far this hasn't balanced my cells. I make 10s2p batteries with brand new molitsel elements 21700 p42a and charge the battery after riding. It only disables charging when a cell reaches 4.2 volts. After a few cycles, some cells remain at 3.9 volts when the battery stops charging. Please make sure it works after a few cycles, otherwise it may damage the battery or cause a fire.
