12.2 Features of GA005 balance charger
(1)
GA005 utilizes microcomputer chips to monitor and control over the whole charging process in
a balanced way with LED indicator to display the charging status at real time.
(2)
Connects to an input power supply (DC 15-18V 1000 mA).
(3)
GA005 is suitable for 7.4V/ 11.1V Li-ion or Li-polymer battery pack.
(4)
GA005 can detect Li-Po battery automatically. GA005 will automatically charge when it finds the voltage
of single cell battery is excessively low. At the same time LED displays as charging status (flash in red).
Control single cell battery voltage at the range of 4.2 ±0.05V to ensure the maximum voltage difference
of single cell in the battery is less than 50 mV.
12.3 Instruction of GA005 balance charger
Status LED
(1)
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. Either the charger or battery may be damaged.
(2)
During charging, GA005 should be put in dry and ventilated place and be far away from heat sources and inflammable
and explosive substances.
(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 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 adapter + GA005 balance charger) and battery.
Please change new one in time when the old battery pack 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.
