Battery Functions
1. Battery Level Display: the status LEDs indicate the current battery level. Press the power button to
check.
2. Communication: battery parameters including the voltage and power level are transmitted to the
aircraft to enable the aircraft to take appropriate action when battery parameters change.
3. Battery Error Self-Diagnosis: the battery can detect errors such as abnormal voltage, current, and
temperature, and issue an alert. The error information will be recorded in the battery.
4. Short Circuit Detection: after the battery is inserted into the aircraft and powered on, the battery will
rst detect if a short circuit exists on the aircraft. If detected, the battery will cut off the power supply
to the aircraft to avoid re.
5. Charging Error Detection: errors that occur during charging are indicated by the status LEDs. When
an error occurs, wait for the battery to x the error automatically. For more information, refer to the
LED Patterns section.
6. Auto Balancing: in certain situations, the battery automatically balances the voltages of the cells.
7. Auto Discharging: if fully charged for more than one day, the battery automatically discharges to
97%. After 7 days, it automatically discharges to 60%.
8. Auto Current Adjustment: the battery intelligently adjusts the charging current based on the
temperature of the battery cells. The battery also supports self-protection based on the environment
temperature.
9. Temperature Control: the battery ensures the temperature difference between the battery cells are
the same and stay within the allowable temperature range.
Refer to the safety requirements listed on the label of the battery before using for the rst time.
Users accept full responsibility for any violations of the safety requirements stated on the label.
The product warranty is void if any battery errors occur due to misuse of the battery.
Using the Battery
Press and then press and hold the power button to power on the battery after it is connected to
the aircraft. When the aircraft lands and the motors stop, press and then press and hold the power
button to power o the battery, and then disconnect the battery from the aircraft.
DO NOT use the battery near heat sources such as a furnace or heater. DO NOT leave the
battery inside a vehicle on hot days.
DO NOT allow the battery to come into contact with any liquid. DO NOT leave the battery near a
source of moisture and DO NOT use the battery in humid environments. Otherwise, the battery
may corrode, potentially resulting in the battery catching re or exploding.
DO NOT use swollen, leaking, or damaged batteries. If your battery is abnormal, contact an
authorized DJI dealer for further assistance.
Make sure the battery is powered off before connecting to or disconnecting from the aircraft.
DO NOT connect or disconnect the battery while it is powered on. Otherwise, the power ports
may be damaged.
