Parameter adjustment method:
1.Adjust the CV potentiometer to set the output voltage as your need according to your load, battery or LED. For example, the mobile phone charging is adjusted to 5V, the 4-string LED voltage is adjusted to 14.8V, and the four-string lithium battery is adjusted to 16.8V. 
2.Set the CC potentiometer counterclockwise for about 30 turns, set the output current to the minimum, connect the load (battery, LED, etc.) and adjust the CC potentiometer to the current you need. For battery charging, after the battery is discharged, it will be connected to the output and adjust the CC to the current you need. (Be sure to use the discharged battery when charging, because the battery is left in the battery.) More, the charging current is smaller).
