brand new and high quality

Features:
Start the first stage of constant current charging, the LED indicator is red, when charging to the rated voltage, turn 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 has been fully charged to 90%-95%, and the battery continues to charge with a small current until it is full.
Over voltage protection
Over current protection
