11.1 Parameters of GA005 balance charger: 

Input voltage Input current Output current Dimension Weight 

DC15-18V 1000mA :::;;aoomA 62.5X47X20.8mm 46g 

11.2 Features of GAOOS 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 1 000 rnA). 

(3) GA005 is suitable for 2-3S (7 .4Vf 11.1V) Li-ion or Li-polymer battery pack. 

(4) Automatically detects 2-3S Lithium battery. GA005 will automatically charge when it finds the voltage of anyone 

cell among the LiPo pack is excessively low. At the same time LED displays as charging status (flash in 

red}. The voltage of anyone cell LiPo is controlled at the level of 4.2 :1: 0.05V to ensure the maximum voltage 

difference of single cell in the battery is less than 50 mV.

2 Step 1 + connect the battery to GA005 LED becomes from red to Saturated solid green. 

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 adapter+ GA005 balance charger) and 

battery pack. Please change new one in time when the old battery is becoming swollen due to long time 

usage. 

(B) 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 1B"C to 2s·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.
