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

Charging temperature is too high
All 4 LEDs blink fast
The battery is abnormal and
unavailable
In the event of charging temperature protection occurring the battery will resume charging once
the temperature has returned to within the allowable range. If one of the other battery protection
mechanisms activates, to resume charging once the issue has been resolved it is necessary to
rst press the Power button to turn the battery o, unplug the battery from the charging device,
and then plug it back in to resume charging.
DJI does not take any responsibility for damage caused by third-party charging devices.
DO NOT charge the battery near ammable materials or on ammable 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.
DO NOT charge the battery immediately after ight. The battery temperature may be too high
and may cause serious damage to the battery. Allow the battery to cool down to close to room
temperature before charging. 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 at the
ideal temperature range can prolong battery life.
In scenarios that meet the following two conditions simultaneously, the battery can be charged
immediately after ight:
a. The temperature of the ight environment was below 30° C.
b. The temperature of the charging environment is below 30° C and there is no direct sunlight.
DO NOT charge the battery near heat sources such as a furnace or heater.
Regularly check the terminals and battery ports. DO NOT clean the battery using alcohol or
other inammable liquid. DO NOT use a damaged battery station.
Keep the battery dry at all times.
