Function description: Start the first stage of constant current charging, the LED light is red, and when it is charged to the rated voltage, it will be converted to the second stage constant voltage charging.
The current slowly decreases. When the charging current reaches the turning current, the LED indicator turns green. At this time, the battery is fully charged to 90%-95%.
The battery continues to charge at a small current until it is full.
