Notice: When a level 2 alarm for low battery of the UAV is sent, the UAV will automatically land at the current
position rather than go home; at this moment, you can switch to the manual mode so that the UAV will go
home. In case of level 1 alarm for low battery of the UAV, or level 2 alarm for low battery of the remote
control or ground station, please decide whether the flight can proceed with caution (it is suggested that the
flight should proceed after replacement of the battery), in order to avoid flight accident resulting from low
battery of the UAV or remote control! When a level 1 alarm for low battery of the UAV is sent, it is suggested
that the throttle joystick should not be pushed to the full position whenever possible, so as to prolong the
flight time. If the throttle joystick stays at the full position for a long time after the said alarm, the UAV will
enter the level 2 low battery state ahead of time.
Use a Battery Indicator to Detect the Battery Level
Check the battery level before using the battery; in case of low battery level, charging is required. Insert the pins of
the battery indicator into the flat cable connector, as shown in the figure below.
Notice: The black wire should be connected to “– ” during connection.
Insert the other end of the flat cable into the port on the power battery as directed by the arrow in the figure below.
After connection, the battery indicator first displays the total voltage (25.2V), and then displays the voltage
