4, Automatically continue to charge and discharge
after the next one .
unplug the battery for 2 seconds, then access the
next battery, the device will automatically continue
to charge and discharge.
5, Fan rating
When the internal temperature of the device reaches
40 ° C, the fan work at the half-speed air volume to
reduce noise. When the internal temperature
reaches 50 ° C, the fan turns on the full speed air
volume to enhance heat dissipation.

calibration voltage function. Use a voltmeter to
measure the actual voltage of each battery, move
the cursor to the corresponding voltage value, and
modify the voltage value to match the voltmeter
value for calibration. After the calibration is
completed, move the cursor to save, short press
once, the buzzer sounds once and the save is
successful. Exit or Turn off device
