Product Manual

• Do not modify, remanufacture, or attempt to insert foreign objects into the
battery
• Do not place heavy objects on the battery or charger
• Stop using or charging the battery immediately if it starts to swell, smoke or
leak
• Use the battery at temperatures between -10°C and 40°C. Extremely
high temperatures may cause a re or explosive damage; extremely low
temperatures may lead to permanent battery damage
• Before ying in a low-temperature environment (between -10°C and 15°C),
fully charge the battery in warmer temperatures, or insert it into EVO and
hover the aircraft at an altitude of 1m until the battery warms up to 15°C or
higher. The battery temperature can be monitored using the mobile app
• Do not use the battery in strong electrostatic or electromagnetic environments
• Do not expose the battery to re, explosions, or other hazards
• The heavier the aircraft loads, the shorter the ight time
If the aircraft falls into the water, remove the battery immediately after you retrieve
it. Leave the battery in an open area and maintain a safe distance until it is
completely dry. Don’t use the battery again. Contact our customer support team
for a replacement.
Battery Charging
It should take a maximum of 80 minutes to fully charge the EVO battery, though
charging times will vary according to the remaining battery level. Other battery
charging notes and words of caution:
• Do not use a damaged battery charger
• When the charger is not in use, we recommend disconnecting it
• Do not charge the battery immediately after ight, as overheat protection will
prevent the battery from being charged before it cools completely
• Overcharging may shorten battery life, so don’t leave the battery unattended
during charging, and remove it after it’s fully charged
We strongly recommend that you go through a charge cycle — wherein you
charge the battery to 100% and then discharge it to 7% or lower — every three
months, or after the battery has been used for 20 consecutive charges.
Battery Storage
In storage as in ight, it’s important not to allow the battery to come in close
contact with moisture or heat sources. Store the battery in a dry and ventilated
area at room temperature (ideally 22°C to 28°C). Other storage notes:
• Keep the battery out of reach of children and pets
