Battery use:
Make sure of the voltage and current of the battery you need to charge
Adjust the constant voltage potentiometer to make sure the output Voltage is about 5V(about).
Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current
potentiometer to make sure the output current to the expected charging current value
The charge current of transfer lamp is default 0.1 times of the charging current (constant current value)
Adjust the constant voltage potentiometer to make sure the output Voltage is up to floating Voltage.
Connected to the battery and try to charging (for previous 5 steps, module input terminal is connected to
power source, output load is NOT connected to batteries).
