User manual
with the  aircraft, flight log data  (including  flight  telemetry) will be  uploaded and maintained  on  Autel 
Robotics  data  servers.  All  telemetry  and  flight  logs  are  stored  on  data  servers  located  within  the 
boundaries of the continental United States, and the data upload occurs automatically only if the Flight 
Log Backup option is enabled. 
The Autel Robotics customer support team doesn’t have access to flight log data except when explicitly 
granted permission by the user via the Autel Explorer
TM
 app. When that permission is  granted, only 
flight logs within the selected date range can be accessed.
Information, including still and motion imagery and data from the aircraft’s sensors, will be stored on the 
aircraft's internal drive. If your aircraft ever needs to be sent to us for service, the information on the 
internal storage unit may be used to diagnose problems with the aircraft. The information will not be 
retained except as required to perform the service or repair. Do not remove or alter the data on the 
internal storage device in any way. Doing so will invalidate all warranty coverage. 
Autel Robotics’ purpose in gathering data is to provide support and service for our customers, and to 
improve the performance of our products. We take your privacy as seriously as we do our own. We will 
consent to the disclosure of uploaded data only when required by law to do so.
Safety Instructions 
Battery Safety 
The  EVO  Ⅱ  is  powered  by  a  lithium-polymer  battery.  The  misuse  of  Li-Po/Li-Ion  batteries  can  be 
hazardous. As such, make sure to strictly follow all the battery usage, charging and storage instructions 
below.
  WARNING! 
•  Only  use  batteries  and  charging  devices  that  came  with  the  aircraft  or  are  sold  by  Autel 
Robotics for use with the EVO Ⅱ. Do not tamper with the battery pack or its charger. 
• Battery electrolytes are highly corrosive. If any electrolyte comes in contact with your skin or 
your eyes,  immediately  flush  the  affected  area  with clean running  water  and seek  medical 
attention. 
Battery Usage   
Always turn off the aircraft before installing or removing the battery. Additional information: 
• Only use batteries and charging devices that came with the aircraft or are sold or authorized by Autel 
Robotics for use with the EVO Ⅱ. Using unapproved batteries or charging devices may result in fire, 
explosion,  leakage,  or  other  hazards.  Autel  Robotics  will  not  be  liable  for  any  consequences 
resulting from the use of third-party batteries or charging devices.
• Do not disassemble, open, crush, bend, deform, puncture, shred, or otherwise intentionally cause 
damage to the battery. Doing so may result in fire, explosion, leakage, or other hazards. 
• If the battery starts to swell, smoke, leak, or show any signs of damage, stop using or charging it 
immediately and submerge it in a container of saltwater. 
• Do not expose the battery to temperatures below -10°C (14°F) or above 40° C  (104°F). Exposing the 
battery to extreme temperatures will reduce its lifespan and may result in fire, explosion, or other 
permanent damage.
• Temperatures below 5°C (41°F) will cause the battery to discharge faster. 
• Do not use the battery in strong electrostatic or electromagnetic environments. 
• Do not expose the battery to fire, explosions, or other hazards. 
• If the aircraft becomes submerged, remove the battery immediately after you retrieve it. Leave the 
battery  in  an  open  area,  away  from  flammable  objects,  and  maintain  a  safe  distance  until  it  is 
completely dry. Don’t use the battery again. Contact our customer support team for a replacement.
