5Low Battery Capacity Warning Function
The low battery capacity warning alerts users when the battery is close to depletion during flight. When it appears,
users should promptly fly back and land to avoid accidental damage. The PHANTOM 2 has two levels of
low battery capacity warning. The default warning low battery threshold are 30% (first level warning) and 15%
(second level warning) respectively.
First Level Battery Low Warning
When battery level drops below 30%, the LED indicators will blink red slowly and the DJI VISION app will
produce the alarm to notify the user. Refer to
<DJI VISION app Low Battery Capacity Warning>
for more
information.
Second Level Battery Low Warning
When the battery level drops below 15%, the LED indicators will blink red rapidly. At the meantime, the aircraft
will gently descent to the ground. The PHANTOM 2 will also begin to descend and land automatically.
After it has landed, keep the throttle stick at its lowest point or execute CSC; refer to
<Starting the Motors>
for more
information about how to execute the CSC. The other option is to push the throttle upward to hover the aircraft
and navigate it to a more appropriate location for landing.
When battery low warning is triggered, you must bring the aircraft back to the home point to avoid
losing the power for the aircraft.
