7.5 Correct Battery Usage Notes
 It’s suggested you purchase a new battery after you have discharged your current battery over 300
times.
 It’s recommended to charge and discharge the battery thoroughly once every 20 charge/discharge
cycles. Users should discharge the battery until there is less than 8% power left or until the battery can
no longer be turned on. Refer to the DJI VISION App for an exact readout of the battery percentage
level. You should then fully recharge the battery to maximum capacity. This power cycling procedure will
ensure the battery is working at its optimal level.
 Turn the power OFF when you have finished flying and remove the battery from its compartment.
NEVER plug or unplug the battery into the aircraft when it is powered on.
 Take the battery out of the aircraft after every flight and store the battery in a safe and secure place. For
long term storage please place the battery with only a 40~50% capacity in a strong battery box securely.
We recommend discharging and charging the battery completely once every 3 months to keep it in good
condition. The capacity should be varied in such a cycle (40%~50%) —0%—100%—(40%~50%).
 Adhere to the notes for the battery in the disclaimer and regard safety as your first priority.
 The battery should be charged in an environment that is between 10 ℃ to 40℃, and be discharged in an
environment that is between -20 ℃ to 60℃. Both charging and discharging should be in an environment
that the relative humidity is lower than 80%.
 It’s suggested that you purchase a new battery if the current battery is swollen or damaged in any way.
 Never try to recharge or fly with a battery that is swollen or damaged in any way.
 Never charge the battery unattended. Always charge the battery on a non-flammable surface such as
concrete and never near any flammable materials.
