915 Generation 5Pcs Ternary Lithium Battery Fast Charging Board 5V To 4.2V

1. The IP2312 uses a full CC/CV charging mode.
2. When the battery voltage is lower than 3V, it enters the trickle charge mode and charges the battery with a charge current of 100mA.
3. When the battery voltage is 3V, enter the constant current charging mode to charge the battery with the set constant current charging current.
4. When the battery voltage is to 4.2V and the charging current is less than 300mA, it enters the constant voltage charging mode. After entering the constant voltage mode, the charging is stopped after 4 minutes, and the battery voltage is detected to be higher than 4.15V: if it is higher than 4.15V, the charging is stopped; otherwise, the charging is continued, and then the detection is performed after 4 minutes.
5. When the battery is fully , if it detects that the battery voltage is lower than 4.1V, it will turn on to charge the battery. Current adjustment instructions:
