When charging, the Charging Station will first charge the battery in the aircraft, and
then the two spare batteries in accordance with their power levels from high to low.
Refer to "LED Descriptions" for more information about the Battery LED Indicators
and Charging Station Power Level LEDs' flashing patterns.
When connected to an external power source, after batteries are
correctly inserted, the charging station will automatically start
charging. There is no need to power on the Charging Station manually.
Make sure the securing board is firmly closed if you still want to charge
the batteries or other devices during transportation after the power
cable is disconnected. The Charging Station can still supply power to
batteries and other devices if it has sufficient power once the power
cable is disconnected.
Disconnect the power cable when charging is complete to power off
the Charging Station.
Disconnected from an External Power Source
The Charging Station can work as a power source to charge batteries and other
devices when it has adequate power.
1. Checking the Power Level
Press the power button once to check current power level of the Charging Station
and make sure the station itself has adequate power.
