Operation Manual:
1.Set the charging initiation voltage: Under the normal voltage display status, press the "Start" button, the module will display the charging initiation voltage, long press this button about 3s, the LED flash, then press the "Start" and "Stop" button to set the vlues.
2.Set the charging stop voltage: Under the normal voltage display status, press the "Stop" button, the module will display the charging stop voltage, long press this button about 3s, the LED flash, then press the "Start" and "Stop" button to set the vlues.
3.Reset:under the normal display status, press the "Start" and "Stop" button at the same time the LED will display"888", then release and finish.(the default charging initiation voltega is 12V and charging stop voltage is 14V)
4. Voltage Setting Calculation: Charging Initiation Voltage= Battery Rated Voltage*0.9; Charging Stop Voltage=Battery Rated Voltage*1.2; Charging Current= Battery Rated Current*0.1
