In this circuit, when it is in charging status, red light flashing shows that it is charging, and the green light flashing shows it is going to be full, then green light is lit completely, then it is full. As long as you have a 12V power supply, after finishing the circuit, you do not install the battery firstly, and adjusting the adjustable resistor in right corner make the battery output be 4.2V, then transferred adjustable resistor in the left corner make the pin 3 of LM358 be 0.16V, then the charging current is 380mA, and the circuit is ultra-fast, and three diodes connected in parallel is used to prevent overheating of LM317, and LM317 must add heat sink. The transistor shown in the figure can choose any model.
