water-soaked place.
(3) When installing the battery, do not exert too much force or exceed the prescribed torque, otherwise it may
cause damage.
(4) Do not touch the remote control when installing the battery.
3. Battery installation
(1) Clean the battery installation position to ensure that there are no metal or other foreign bodies.
(2) Fasteners should be fastened during installation to prevent the battery from falling off.
(3) When test the drone ,observe whether there is any abnormal condition .
（2）Battery Maintenance
1. If the battery is not used for a long time, it is recommended to maintain the battery once every 15 days;
2. In normal use, if the battery endurance decreases significantly or the unit cell difference exceeds 50mV,we
advise maintain the battery.
3. In the maintenance mode, the charger uses low current to charge, discharge and balance the battery, so that
the voltage of each battery unit can be adjusted to about 3.85V.
（3）Cautions
● Do not hit the battery hit when handling.
● Do not short-circuit the battery or will cause serious damage.
● Do not transport or store batteries with metal at any time.
● Do not knock, throw, tramp, puncture, disassemble the battery.
● If the electrode is dirty or rusty, it should be cleaned in time, otherwise it may lead to battery damage or poor
contact and function failure.
● Please use the special charging device for Black Dragonfly UAV battery. Do not use any other charger.
● Do not overheat the battery cell at any time.After the temperature of the cell is as high as 60℃, there will be
safety risks, or even combustion.
● Do not disassemble the battery and reassemble or change the wiring. It is dangerous to reassemble one piece
of battery cell with another group of batteries after disassembling.
● Do not directly touch the battery with leakage. If the electrolyte is splashed on the eyes or skin accidentally,
please wash with water immediately. In serious cases, please seek medical advice immediately.
Before charging / discharging battery
●Please check the battery voltage and electric quantity carefully before charging or using.
● Do not over discharge or overcharge the battery (the voltage of each cell after discharging is not less than
3.3V and not higher than 4.25V),over discharge and overcharge is easy to damage the battery.
● Use a clean wet cloth to clean the battery shell and connector, and dry cloth to wipe the water stains.Do not
use tools that are easy to generate static electricity, and do not use corrosive organic solvents, otherwise the battery
will be damaged.
