11.6 Matters needing attention
(1) During charging, GA005 should be put in dry and ventilated place and be far away from heat sources and
inflammable and explosive substances.
(2) GA005 is only used to charging a 2S or 3S Li-ion or Li-polymer battery. It is forbidden to simultaneously
charge two or more sets of batteries packs. Either the charger or battery may be damaged.
(3) When charging, the battery should be removed from your helicopter. Never leave the charger unsupervised
during the process of charging in order to avoid risk of accidents.
(4) Never immediately charge your battery as soon as the flight is finished, or when its temperature doesn’t cool
down. Otherwise the battery will take a risk in swelling, even catch
a fire.
(5) Ensure the correctness of polarity before connecting the battery to charger.
(6) Avoid drop and violence during the process of charging. Drop and violence will result in internal short circuit
of the battery.
(7) For the sake of safety, please use original charging equipment (wall a GA005 balance charger) and
battery pack. Please change new one in time when the old battery is becoming swollen due to long time
usage.
(8) If it is retained in the charger for a long time after saturated, the battery may automatically discharge. When
the charger detects that the voltage of individual cells is lower than the rated voltage, it will re-charge until
saturated. Frequently charging and discharging will shorten the lifetime of your battery.
11.7 Maintenance of battery pack
(1) The battery should be put in dry and ventilated place. The storage temperature of the environment is ranged
from 18
*
C to 25
*
C.
(2) Please avoid frequent charging and excessive discharging the battery in order to prolong its life cycle.
(3) It is a must to maintain the battery before long-term storage. That is to charge the battery to the level of 50-
60% saturation.
(4) If the storage term is over 1 month, it is advised to monthly check the voltage of every cell of the battery .
The voltage of every cell should be not less than 3V. Otherwise, please refer to the above article (3).
(5) From the view point of protection, new battery should be motivated before usage. That is to charge and
discharge 3-5 times, but discharge is not less than the level of 70% saturation. This process will make the
battery lifetime longer and voltage more stable.
