Intelligent Battery
Introduction
The TB51 Intelligent 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 Battery. The rmware for the Intelligent Battery is included in the aircraft
rmware. Make sure the rmware of all intelligent batteries is updated to the latest version.
Battery Features
The Intelligent 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 60%. Discharging
the battery level to 60% can extend battery life.
3. Battery Cell Balanced: the voltage of the battery cells are automatically balanced to avoid
overcharge of over-discharge.
4. Overcharge Protection: the battery stops charging automatically once fully charged.
5. Temperature Detection: prevents any damage, the battery only charges when the
temperature is between -20° to 45° C (-4° to 113° F).
6. Overcurrent Protection: the battery stops charging if an excess current is detected.
7. Over-Discharge Protection: ensures ight safety and allow users to have as much time as
possible to deal with emergencies, over-discharge protection is disabled to allow continuous
output. Pay attention to the remaining battery level during flight and land or Return to
Home immediately when prompted to do so in the app. Otherwise, the battery may be
dangerously over-discharged. 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. When the
battery is not used in ight, over-discharge protection will be enabled once the battery level
is lower than 5% to avoid battery damage.
8. Short Circuit Protection: the power supply is automatically cut off 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.
The battery will enter Deep Hibernation mode once the power is too low. At this time, the
battery LEDs will not function after pressing the battery level button. Insert the battery into
the charging hub to charge for activation.
11. Communication: information about the voltage, capacity, and current of the battery is
transmitted to the aircraft.
12. Warming up: ensures the battery operates normally at a low temperature. Refer to the
Warming the Battery section for more information.
