
After taking off and the above conditions are met, when the Autel Enterprise App prompts
a low battery alarm, it is recommended to immediately choose a suitable place for landing
operations. During the automatic landing process, the aircraft can still be controlled by
the remote controller.

In the extreme cold environment, even if the self-heating function is adopted, the battery
temperature may still not reach the usable temperature, please add insulation measures
during the heating process.

In order to get the best performance from the batter
y, it is recommended to keep the
battery temperature between 15°C to 35°C before flying.

In a low temperature environment, the self-heating time of the battery may be longer. It is
recommended that the user keep the battery warm in advance to shorten the self-heating
time.
3.3.2 Additional Features
 Low Battery Protection
If the battery is low, the battery will automatically enter sleep mode to prevent
over-discharge. In this mode, the battery does not respond when the power button is pressed.
To wake up the battery, it can be connected to a charger.
 Charging Temperature Detection
If the temperature is lower than 5℃ (41℉) or higher than 45℃ (113℉) during charging, the
battery will stop charging.
 Current Protection
When the charging current is too high, the battery will stop charging.
 Overcharge Protection
Charging will stop automatically when the battery is fully charged.
 Balance Protection
The voltage of each battery cell is kept balanced to maximize the performance of the
battery.
 Short Circuit Protection
Once a short circuit is detected, the power supply will be cut off.
 Power Saving Mode
The battery will shut down after 30 minutes of inactivity.
 Communication
When using the battery, the aircraft is continuously synchronized with the battery to
provide real-time information, including voltage, capacity, current, temperature, and more.
 Ultra Low Power Mode
When the battery is idle for 12 hours and the charge is less than 8%, the battery will enter
the ultra-low power mode to reduce self-consumption. When entering ultra-low power mode, it
needs to be activated by a charger before it can continue to use normally.
