Short-circuiting the pin header can convert it into 3-string charging mode, and leaving the pin header open can obtain 2-string charging capability.
Since the multimeter is out of power, the measured voltage may have errors. The chip supports lithium batteries of various voltages and can be switched through external resistors.
Potentiometer is used to adjust the charging current
