Hi 10 K multiturn trimpot is used in this circuit. In this way, the positive or negative current of the base leg of the c1815 transistor is controlled and the relay is activated to reach the desired value. This circuit is a simple intelligent charge control circuit and has an extremely simple and convenient structure. The automatic charge cutoff circuit prevents your battery from overcharging. and one of the essential elements in battery charging. Thank you for watching Zafer YILDIZ
