Battery Level LEDs During Charging
The table below shows battery level during charging.
The battery cannot be charged if the aircraft is powered on and the aircraft cannot be powered
on during charging.
DO NOT charge an Intelligent Flight Battery immediately after flight as the temperature may be
too high. Wait until it cools down to room temperature before charging again.
The charger stops charging the battery if the battery cell temperature is not within the operating
range of 41° to 104° F (5° to 40° C). The ideal charging temperature is 71.6° to 82.4° F (22° to 28° C).
The Battery Charging Hub (not included) can charge up to three batteries. Visit the official DJI
Online Store to learn more.
Fully charge the battery at least once every three months to maintain battery health.
DJI does not take any responsibility for damage caused by third-party charger.
Discharging
It is recommended to discharge the Intelligent Flight Batteries to 30% or lower. This can be done
by flying the aircraft outdoors until there is less than 30% charge left.
The blinking frequency of the battery level LEDs will be different when using different USB
charger. If the charging speed is fast, the battery level LEDs will blink quickly. If the charging
speed is extremely slow, the battery level LEDs will blink slowly (once every two seconds). It is
recommended to change the Micro USB cable or USB charger.
If there is no battery in the aircraft, LED 3 and 4 will blink three times alternatively.
The four LEDs blink simultaneously to indicate the battery is damaged.
