3.5.6 Low Temperature Notice
« When using the battery in a low-temperature environment
(32°F-41°F / 0°C-5°C), please make sure that the battery is fully
charged. The flight time will be reduced as the discharge capacity
of the battery will be reduced when working in a low-temperature
environment.
+ Inalow-temperature environment, due to the battery output power
limitation, the aircraft's wind resistance and flight performance will
be reduced. Please be careful.
+ Pay more attention when flying in low-temperature and
high-altitude environments.
3.5.7 Daily Preservation Advice
* Itis recommended to charge and discharge it once a month, do not
store with a full charge, keep 50%-60% of the power, the storage
temperature is 50°F-104°F (10°C-40°C), and the best storage
temperature is 66.2°F-69.8°F (19°C -21°C).
If water enters the battery and the battery protection board fails,
the battery cannot be used normally. Do not use the battery in rain
or in a humid environment, as this may cause the battery to
self-ignite or even explode.
If the battery is squeezed, deformed, and dropped from a high
altitude, it is forbidden to use it again.
- Prolonged exposure to high temperatures is forbidden. High
temperatures will cause the internal pressure of the battery to
become too high and cause an explosion.
The positive and negative poles are short-circuited for a long time
(such as the battery contacts have water, short-circuit caused by
hair or foreign objects, etc.). If it exceeds 30 minutes, the protection
board IC will fail and disconnect, and the battery cannot be used
normally.
