Detaching the Propellers
Use the screwdriver to detach the propellers from the motors.
Propeller blades are sharp. Handle with care.
The screwdriver is only used to mount the propellers. DO NOT use the screwdriver to disassemble
the aircraft.
If a propeller is broken, remove the two propellers and screws on the corresponding motor and
discard them. Use two propellers from the same package. DO NOT mix with propellers from other
packages.
Only use ocial DJI propellers. DO NOT mix propeller types.
Purchase the propellers separately if necessary.
Make sure that the propellers are installed securely before each ight. Check if the screws on the
propellers are tightened every 30 hours of ight time (approx. 60 ights).
Make sure all propellers are in good condition before each ight. DO NOT use aged, chipped, or
broken propellers.
To avoid injury, stand clear of and do not touch propellers or motors when they are spinning.
DO NOT squeeze or bend the propellers during transportation or storage.
Make sure the motors are mounted securely and rotating smoothly. Land the aircraft immediately if a
motor is stuck and unable to rotate freely.
DO NOT attempt to modify the structure of the motors.
DO NOT touch or let your hands or body come in contact with the motors after ight as they may be hot.
DO NOT block any of the ventilation holes on the motors or the body of the aircraft.
Make sure the ESCs sound normal when powered on.
Intelligent Flight Battery
The DJI Mini SE Intelligent Flight Battery is a 7.7 V, 2250 mAh battery with smart charging and
discharging functionality.
Battery Features
1. Balanced Charging: during charging, the voltages of the battery cells are automatically balanced.
2. Auto-Discharging Function: to prevent swelling, the battery automatically discharges to approx. 96%
of the battery level when it is idle for one day, and automatically discharges to approx. 72% of the
battery level when it is idle for nine days. It is normal to feel moderate heat being emitted from the
battery during the discharging process.
3. Overcharge Protection: the battery stops charging automatically once fully charged.
4. Temperature Detection: To prevent damage, the battery only charges when the temperature is
between 5° and 40° C (41° and 104° F). Charging stops automatically if the temperature of the
battery exceeds 50° C (122° F) during the charging process.
5. Overcurrent Protection: the battery stops charging if an excess current is detected.
6. Over-discharge Protection: discharging stops automatically to prevent excess discharge when the
battery is not in ight use. Over-discharge protection is not enabled when the battery is in ight use.
7. Short Circuit Protection: the power supply is automatically cut if a short circuit is detected.
