Precautions for low-temperature use
• When the battery use in a low-temperature environment (-10°C to 5°C), the
battery capacity and flight time will be drastically reduced. It is recommended to
take off when the battery is fully charged. Please fully charge and keep the
battery warm before use.
• In a low-temperature environment, it is recommended to preheat the battery to
above 5°C before flying, and it is better to preheat to above 20°C.
• Before flying in a cold environment, insert the battery into the aircraft to warm up
for 1 to 2 minutes, and take off after the battery is fully warmed up.
Battery Charging
• Always use a SwellPro Approved charger to charge the battery of the drone, and
the radio controller. SwellPro takes no responsibility if the battery is charged
using a non-SwellPro charger.
• To avoid any potential accidents happening, please do not leave the battery
charging unattended.
• Do not charge the battery near flammable materials, or on flammable surfaces,
such as carpet or wood.
• Disconnect the charger when not in use.
• Do not clean the charger with denatured alcohol or other flammable solvents.
• Never use a damaged charger.
Battery Storage and Transportation
• If the drone is not being used for a long period of time, ensure to fully charge the
intelligent flight battery and remote controller for storage. To prevent the battery
from over-discharge, recharge the battery every 2 months.
• Do not leave both the intelligent flight battery and remote controller battery
unattended for an excessive period of time (longer than 2 months). As the
battery discharge over time, long storage time without recharge would result in
battery over-discharge and cause permanent damage to the battery.
• It is recommended to fully charge the battery before put into storage, as the
higher the battery level, the longer the battery can be stored.
• Keep batteries out of the reach of children and pets.
• Do not leave the battery near heat sources, such as a furnace, heater, or
exposure to strong direct sunshine, for example: in cars
• The ideal storage temperature is 20°C ~ 28°C.
• Keep the battery in a dry and ventilated environment
• Never drop the battery into the water, or store it in places where there is a
possibility of water leakage.
• Do not drop, strike, impale, pierce, or manually short-circuit the battery.
• Keep the battery away from metal objects, such as watches, jewelry, and hairpins.
