Intelligent Flight Battery
Introduction
The TB30 intelligent flight battery is equipped with high-energy battery cells and uses an advanced
battery management system to power the aircraft. Only use a DJI-approved charging device to charge
the intelligent ight battery. Make sure to fully charge the intelligent ight battery before using it for the
rst time. The rmware for the intelligent ight battery is included in the aircraft rmware. Make sure the
rmware of all intelligent ight batteries is updated to the latest version.
Battery Features
The intelligent ight battery has the following features:
1. Battery Level Display: The battery level LEDs display the current battery level.
2. Battery self-discharge will be triggered if the battery level is higher than 50%. Discharging the
battery level to 50% can extend battery life.
3. Balanced Charging: During charging, the voltages of the battery cells are automatically balanced.
4. Overcharge Protection: The battery stops charging automatically once fully charged.
5. Temperature Detection: To prevent any damage, the battery only charges when the temperature is
between -20° and 40° C (-4° and 104° F).
6. Overcurrent Protection: The battery stops charging if an excess current is detected.
7. Over-Discharge Protection: During flight, to ensure flight safety and allow users to have as
much time as possible to deal with emergencies, over-discharge protection is disabled to allow
continuous output. Therefore, pay attention to the remaining battery level during ight and land or
return to home immediately when prompted to do so in the app. Otherwise, the battery may be
dangerously over-discharged. When charging, an over-discharged battery may be a re hazard. To
prevent this, the battery will be locked and can no longer be charged or used.
8. Short Circuit Protection: The power supply is automatically cut if a short circuit is detected.
9. Battery Cell Damage Protection: The app will display a warning prompt when a damaged battery
cell is detected.
10. Hibernation Mode: The battery will be in Hibernation mode when not in use to save power.
11. Communication: Information about the voltage, battery level, and current of the battery is
transmitted to the aircraft.
12. Heating: The feature ensures the battery operates normally at a low temperature. Refer to the
“Warming the Battery” section for details.
13. Waterproofing and Dustproofing: After being installed in the aircraft, the battery meets the IP55
rating standards.
Refer to the user manual, safety guidelines, and battery labels before use. Users shall take full
responsibility for all operations and usage.
If only one battery is usable after takeo, land the aircraft promptly and replace the batteries.
PSDK port has a built-in temperature sensor. If the payload power is too large causing the
device to overheat, the aircraft will automatically cut o power supply for the payload.
Use batteries provided by DJI. DO NOT use other batteries.
