EVO Nano Series User Manual


Be sure to charge the battery fully before each flight. If the aircraft enters the low battery
alarm mode, it is necessary to land the aircraft, stop flying, replace or charge battery as
soon as possible.
 Never decompose, scratch, extrude, bend, pierce, cut, distort or damage the battery in
other forms. Otherwise the fire, explosion, leakage or other dangers may be caused.
 Once the battery is found with bulge, smoke, leakage or any damage, it is necessary to
stop use or charging immediately and soak the battery into a vessel containing saline
water.
 Please use the battery at the suitable temperature (-10°C~40°C). The use at high or low
temperature will affect the battery life. Too high temperature may cause fire or
spontaneous combustion; too low temperature may cause the permanent damage of
battery.

When the battery is at low temperature lower than 10°C, it can be inserted into the
aircraft for warming; the flight is allowed after the battery is fully warmed up. It is
optimal to warm up to 20℃ above.
 Due to the battery output power limitation under the low temperature environment, the
wind resistance of aircraft will reduce and its flight performance will degrade. Please
operate with care.

When the battery is used in low temperature environment (0~5°C), the battery shall be
full. The discharge capacity of battery will reduce when it operates in low temperature
environment, so first turn on the aircraft to warm up the battery.
 Never use the battery in strong static or electromagnetic environment.
 Never expose the battery to open fire, explosion or other danger.

Never place the battery in microwave oven or pressure cooker.
 If the aircraft falls into water, the battery shall be taken out immediately after it is
recovered. Place the battery in an open space and keep a safe distance till that the battery
is fully dried. Stop the use of the battery, and contact the customer service center for
replacement.
2. Charging
 At most 90 minutes are required to fully charge the aircraft battery, but the charging time
is related to the remaining battery level.
 Never use the damaged battery charger.
 When the charger is not used, disconnect it from the aircraft battery and power supply.
