Product Function and Wiring Diagram

In the state of setting the voltage value, the start button plays the role of an up button, and the stop button plays the role of a down button.

Set startup voltage

Under normal display voltage status, press the start voltage button once to display the start charging voltage. Long press the start button, the digits will flash. Set the starting charging voltage value through the start and stop buttons.

Set stop voltage

Under normal voltage display, press the stop voltage button once to display the stop charging voltage. Long press the stop button, the number will flash, and set the stop charging voltage value through the start and stop buttons.

Restore factory settings

Press and hold the start/stop button while powered on, and the digital display will show 888, which will restore the common battery charging voltage parameter table (for reference only) to the factory settings.

Method for determining charging voltage:

By labeling, the charging voltage range and current size of the battery can be determined. If only the voltage and capacity of the battery are known, the commonly used voltage and current sizes can be calculated based on the voltage and capacity as follows:

Battery charging usually uses slow charging, which means the initial charging voltage is about 1.2 times the rated voltage, and the charging current is adjusted to about 1/10 of the rated capacity current of the battery. For example, the charging voltage of a 6V 50AH battery is around 7.2 volts, and the charging current is adjusted to 5A

Reference formula:

Charging voltage=rated voltage x1.2

Charging current=rated current x0.1
