Kind tips: If the battery is not in use for a long time, it should be charged with 40%~65% of the electricity, and it should be taken out from the drone and stored in a dry and cool environment, and the battery should be charged every 3 months to avoid excessive storage time, which may cause damage to the battery due to self-discharge. The battery is too low, resulting in irreversible capacity loss. Use the DJI original charger to charge the battery. Do not use inferior chargers to charge the battery to avoid excessive current, unstable output and damage to the battery or permanent damage to the battery hardware contacts.
