Charging
Be sure to fully charge the aircraft battery each time before flight. The aircraft battery must be
charged using the officially supplied dedicated charger. With 5V 2A adaptor, the charging time is
about 270 minutes.
Please charge the battery as the following steps:
Step1: Connect the USB power adapter and the battery balanced charger with a USB cable;
Step2: Connect the USB power adapter with a household power outlet;
Step3: Insert the flight battery into the balanced charger and make sure the connection is secure.
Attention:
● Adult supervision is needed when the aircraft is charging. Batteries are only to be charged
under adult supervision.
● Do not short circuit and squeeze the battery to avoid explosion.
● The battery should not be short-circuited, decomposed or put into the fire; and the battery
should not be placed in high temperature and heated places (such as in the fire or near the
electric heating device).
● The model can only use the recommended charger. Regular checks should be made to
check whether the charger's wires, plugs, housing and other components are damaged.
When damaged, the charger should be stopped using until repaired.
● Charger is not a toy; charger can only be used indoors.
● After the flight, the battery needs to be charged before storing. If not using it, it is
recommended to charge the battery at least once a month to avoid permanent battery
damage due to excessive discharge.
● Only 5V USB power adapters that meet local laws and regulations can be used.
