• Charge the battery at a temperature range of 0° to 40° C (32° to 104° 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.
• DO NOT charge the battery immediately after flight. 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.
• In scenarios that meet the following two conditions simultaneously, the battery can be charged
immediately after flight:
a. The temperature of the flight 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 resources such as a furnace or heater.
• Regularly check the terminals and battery ports.
• DO NOT clean the battery using alcohol or other inflammable liquid.
• DO NOT use a damaged battery charger.
• Keep the battery dry at all times.
• The battery stops charging when charging is complete. It is recommended to disconnect the
battery once charging is complete.
• Make sure the battery is powered off before charging. Otherwise, the battery ports may be
damaged.
Battery Storage
Disconnect the battery from the aircraft and check if there is any buildup in the battery port. When
transporting or storing two or more batteries, make sure to follow the illustration below.
• Keep batteries out of the reach of children and animals. Seek professional medical
attention immediately if a child swallows any battery part.
• If the battery level is critically low, charge the battery to a power level of 40% to 60%.
• DO NOT store a battery with a low power level for an extended period. Otherwise, the
performance will be negatively affected.
• DO NOT leave the battery near heat sources such as a furnace or heater. DO NOT leave
the battery inside a vehicle on hot days.
• The battery must be stored in a dry environment.
• DO NOT place the battery on or near wires or other metal objects such as eyeglasses,
watches, jewelry, and hairpins. Otherwise, the battery ports may be short-circuited.
• DO NOT attempt to transport a damaged battery or a battery with a power level higher
than 30%.
• Make sure the battery is placed on a flat surface.
