sleep mode to avoid damage. Under this mode, there will be no reaction when pressing the
power button. To wake up the battery, it is allowed to connect it with charger.
3) Charging temperature protection: the battery will stop charging in the case of charging
temperature lower than 5ºC (41ºF) or higher than 45ºC (113ºF).
4) Overcurrent protection: the large charging current will seriously damage the battery, so the
battery will stop charging in the case of excessive charging current.
5) Overcharge protection: the battery will automatically stop charging after it is fully charged.
6) Balanced protection: each battery unit shall maintain voltage balance to avoid overcharge
or overdischarge.
7) Overdischarge protection: the battery will automatically disconnect the power output
function when it is not used and completes the self-discharge period. This function is disabled
in flight.
8) Short-circuit protection: the power supply will be disconnected once the short circuit is
detected.
9) Power-down mode: the battery will turn off if there is no operation within 30 minutes.
10) Communication: during use, the aircraft will be continuously synchronous with battery to
provide the real-time information, including voltage, capacity, current, and temperature.
11) Low power consumption mode: the battery will enter the low power consumption mode
when the battery level is lower than about 8% to reduce the own power consumption. To
recover the battery from the low power consumption mode, it shall be activated by charger.
2.3.3 Precautions
1. Use
Please be sure to turn off the aircraft power before installing or disassembling aircraft
battery.
It is only allowed to use the battery and charger sold or authorized by Autel Robotics for
EVO Nano series. The use of any unapproved battery or charger may cause fire,
explosion, leakage or other dangers. Autel Robotics will assume no responsibility for any
consequence of using the battery or charger of third party.

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.

The charging is allowed only after the battery is cooled to room temperature. If the
battery is connected with the charger immediately after flight, the overtemperature
protection function may be activated to stop battery charging till that the battery is fully
cool.
Do not turn on the aircraft during charging. The charging is not supported when the
aircraft is on.
The allowable battery charging temperature is 5°C~45°C. If the battery cell temperature
is not within this range, the battery management system will be prohibited from charging.
The optimal charging temperature range is 22°C~28°C. The charging in this range can
prolong the battery life.
For EVO Nano series, the multiple chargers are optional to charge multiple batteries at
the same time. You can access to Autel Robotics Online Mall to purchase accessories.
The battery shall be recharged once every about three months to maintain its activity.
Autel Robotics will assume no responsibility for any consequence due to the use of
non-official standard charger.
3. Storage and transportation
The battery shall be protected from close contact with water source or heat source when
storage. The battery shall be stored in a dry and well-ventilated place in room
temperature (ideal temperature of 22°C~28°C (72°F~ 82°F)).
The battery shall be kept out of the reach of children and pets.
Never place the battery in direct sunlight or near sharp object, water, metal or reactive
chemical.
The storage of the battery in extreme temperature will shorten the battery service life. If
the battery is not used for 1 day above, it shall be stored in -10°C (14°F)~30°C(86°F).
Otherwise, the battery damage or failure may be caused.
If the battery is not used for long, the battery service life will be shortened. Never
transport the damaged battery. Once the battery needs to be transported, it shall be
discharged to 20~30%.
4. Disposal
The battery must be thoroughly discharged before it is discarded in a designated battery
recycling bin.

The battery is a dangerous chemical, so it is forbidden to be discarded in ordinary dustbin.
For more details, please abide by the local recycling and disposal laws and regulations.

out self-test and calibration. Please ensure that there is no object that may hinder the
gimbal motion around the gimbal.
The gimbal contains precision components. In the case of collision or damage, the
precision components may be damaged to cause performance reduction of the gimbal.
Please protect the gimbal camera from physical damage.
The gimbal shall be kept clean and avoided touching sand, stone and other objects,
otherwise the gimbal motion may be hindered, affecting its performance.
Never add any object on the camera gimbal, otherwise this may affect the gimbal
performance and even cause the motor burnout.
Before flight, ensure that there is no any sticker or foreign object on the gimbal, and
place the aircraft on the flat and open ground. Never collide with the gimbal after power
on.
If any ground object collides with the gimbal or the gimbal is impacted by an excessive
external force (such as being collided or broken) when it is placed on the rugged ground
or grassland, the gimbal motor may become abnormal.
