Note that batteries are volatile equipment and can malfunction or catch fire with wrong usage.
Remove batteries from all equipment when stored for long periods.
Tip:
The battery is 30-50% pre-charged, please make sure it is fully charged before the first-time use.
Store the battery disconnected from the drone at 30-50% charged, not fully charged, and don't allow the battery voltage to drop below 3.7V. If not adhering to this, swelling of the battery can occur.
