DJI Intelligent Flight Battery Functions
1. Battery Level Display: The LED indicators display the current battery level.
2. Auto-Discharging: To prevent swelling, the battery automatically discharges to below 70% of
the total power when it is idle (press the power button to check that the battery level will cause
the battery to exit idle state) for more than 10 days to prevent swelling. It takes around 3 days to
discharge the battery to 65%.It is normal to feel moderate heat emitting from the battery during
the discharge process. Discharge thresholds can be set in DJI GO 4.
3. Balanced Charging: Automatically balances the voltage of each battery cell when charging.
4. Overcharge Protection: Charging automatically stops when the battery is fully charged.
5. Temperature Detection: The battery will only charge when the temperature is between 5 °C (41°F)
and 45°C (113°F).
6. Over Current Protection: The battery stops charging when a high amperage (more than 10 A) is
detected.
7. Over Discharge Protection: Over-discharging can seriously damage the battery. Current output will
be cut off when the battery cell is discharged to 2.8 V when not in ight mode. For extended ight
times, over-charging protection is disabled as batteries discharge during ight. In this instance, a
battery voltage below 2 V may cause a safety hazard such as a re when charged. To prevent this,
the battery will not be able to charge if the voltage of a single battery cell is below 2 V. Avoid using
any batteries matching this description and avoid serious over-discharging to prevent permanent
battery damage.
8. Short Circuit Protection: Automatically cuts the power supply when a short circuit is detected.
9. Battery Cell Damage Protection: DJI GO 4 displays a warning message when a damaged battery
cell is detected.
10. Sleep Mode: Sleep mode is entered to save power when the aircraft is not ying.
11. Communication: Information pertaining to the battery’s voltage, capacity, current, etc. is
transmitted to the aircraft’s main controller.
12. Pairing Batteries: Powered by two batteries (with battery cells connected in parallel), the aircraft
requires the two batteries to have similar properties, e.g. internal resistance. Pairing batteries in
the beginning is recommended. Pairing can be done using DJI GO 4. DJI GO 4 will also prompt
you when batteries that are not paired are not in use. The Intelligent Flight Battery Charging Hub
will charge paired batteries simultaneously. Stickers are provided for marking paired batteries.
13. Heating: Batteries are able to work even in cold weather, ensuring a safe ight. Refer to "Using
the Battery" section for details.
14. Waterproof and Dustproof: The vehicle’s new airframe design improves the Ingress Protection
Rating to IP43 in accordance with the global IEC 60529 standards.
Refer to the Disclaimer and Intelligent Flight Battery Safety Guidelines before use. Users
take full responsibility for all operations and usage.
Charging the Intelligent Flight Battery
The Intelligent Flight Battery Charging Hub is designed for use with the Battery Charger. It charges
up to four Intelligent Flight Batteries simultaneously. The battery pair with more stored power will be
charged rst. The Charging Hub will intelligently charge batteries in sequence according to battery
power levels from high to low, if batteries are not paired. Pairing can be carried out using the DJI
GO 4 app. The Micro USB port is used for rmware updates.
