Backup Battery
The dock features a backup battery with a capacity of 12 Ah and a maximum runtime of more
than five hours. If the dock is powered off due to an emergency power outage, the backup
battery can provide power to the dock so that the aircraft can safely return to the dock and
land.
• After a power outage, the dock does not support functions such as aircraft charging,
air conditioning, and heating of the dock cover and wind speed gauge. Always check
any malfunctions in time.
• Check and x the malfunctions as soon as possible to restore power to the dock. Make
sure to turn o the backup battery switch if the power supply cannot be restored and
the dock is not used for an extended period of time. Otherwise, the backup battery
will be over-discharged. Replace the backup battery if over-discharged.
Charging the Backup Battery

to open.
2. Turn on the AC power switch (A) to power on the dock. Turn on the backup battery switch (B)
