The table below shows battery protection mechanisms and corresponding LED patterns.
LED1 LED2 LED3 LED4 Blinking Pattern Battery Exception Item
LED2 and LED4 blink
three times per second
Aircraft short circuit
LED2 blinks twice per
second
Overcurrent detected
LED2 blinks three times
per second
The battery system is abnormal
LED3 blinks twice per
second
Overcharged detected
LED3 blinks three times
per second
Charging device over-voltage
LED4 blinks twice per
second
Charging temperature is too low
LED4 blinks three times
per second
Charging temperature is too high
All 4 LEDs blink fast
The battery is abnormal and
unavailable
If a short circuit occurs, unplug the battery, resolve the issue on the aircraft, and plug in the
battery.
If the charging temperature is abnormal, wait for the charging temperature to return to normal.
The battery will then automatically resume charging without the need to unplug and plug the
charging device again.
For other situations, after resolving the issue (overcurrent, excess battery voltage due to
overcharging, or excess charging device voltage), press the power button to cancel the LED
indicator protection alert and unplug and plug in the charging device again to resume charging.
DJI does not take any responsibility for damage caused by third-party charging devices.
DO NOT charge the battery near flammable materials or on flammable surfaces such as
carpet or wood. DO NOT leave the battery unattended during charging. There should be a
distance of at least 30 cm between the battery station and any charging batteries. Otherwise,
the battery station or charging batteries may be damaged by excessive heating and may
even lead to a re hazard.
The battery temperature will be high after a ight. Place the battery into the DJI Air-Cooled
Heat Sink or a third-party air-cooled heat dissipation device to charge it. Otherwise, charging
may be disabled. Refer to the DJI Air-Cooled Heat Sink manual document for its usage
instructions. Charge the battery at a temperature range of 0° to 60° C (32° to 140° F). The
ideal charging temperature range is 22° to 28° C (72° to 82° F). Charging within the ideal
temperature range can prolong battery life.
DO NOT immerse the battery in water to cool it down or when it is charging. Otherwise,
the battery cells will corrode causing serious damage to the battery. The user accepts full
responsibility for any damage to the battery caused by immersing the battery in water.
