Charging the Battery
Before using the Intelligent Flight Battery, be sure to fully charge it.
Please use a 5V/3A USB charging plug.
In the charging state, the battery power indicator will flash and
indicate the current charge level; when the fourth indicator light is
always on, it indicates that the charging is complete.
After charging is complete, please remove the charger in time.
Daily Preservation Advice
It is recommended to charge and discharge it once a month, do not
store it with a full charge, keep 50%-60% of the power, the storage
temperature is 10-40°C, and the best storage temperature is19-21°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 tem-
peratures 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 water coming out of the battery contacts, short-circuiting
caused by foreign objects in the hair, etc.). If it exceeds 30 minutes,
the protection board IC will fail and disconnect, and the battery
cannot be used normally.
It is forbidden to use fast chargers that exceed the battery's rated
power for charging. It is recommended to use a 5V/2A or 5V/3A
charger. If the aircraft has not been used for a month, the battery
must be removed to prevent the battery from being discharged for a
long time.
