battery for 2 seconds, connect to the next battery, the
device will automatically continue to charge and
discharge, you can start and stop this function in the
settings menu
4. Fan level
When the internal temperature of the device exceeds
45°C, the fan turns on half-speed air volume to reduce
noise. When the internal temperature exceeds 53°C, the
fan turns on full-speed air volume to enhance heat
dissipation.
6. Manually calibrate the voltage
In the shutdown state, press and hold the [roller]
without releasing, connect the power supply, and the
system will enter the manual voltage calibration function.
Use a voltmeter to measure the actual voltage of each
battery, move the cursor to the corresponding voltage
value, modify the voltage value to be consistent with the
@ToolkiRC 2021

voltmeter value, and achieve calibration. After the
calibration is completed, move the cursor to save, short
press once, the buzzer will beep once, the save is
successful. Just exit or shut down
7, fully charged
When the lithium battery is fully charged, it will
prompt "Fast charge is done". If the battery is not
removed, the constant voltage trickle charge will be
performed automatically to make the battery reach a
more full state.
