Your aircraft comes with a 2S 7.4V 150mAh 45C 
Li-Po battery and a 2S 7.4V DC Li-Po battery 
charger that requires a 12V (11V–14V) DC power 
source. 

Refer to the charging warnings. It is recommended 
to charge the battery pack while you are inspecting 
the aircraft. The flight battery will be required to 
confirm proper aircraft operation in future steps.

Battery Charging Process

NOTICE: 

Charge only batteries that are cool to the 

touch and are not damaged. Look at the battery to 
make sure it is not damaged e.g., swollen, bent, 
broken or punctured.

1.   Gently press the battery connector into the 

charge port located on the front of the charger. 
The connector of the battery is specifically 
designed to allow it to fit into the charge port 
one way to prevent reverse polarity connection. 
However, check for proper alignment and 
polarity.

2.  Press the button on the charger. The red LED 

will illuminate, indicating charging has begun. 

Charging a fully discharged (not over-discharg-
ed) 150mAh battery takes approximately 20–30 
minutes at the charger’s 300mA charge rate. The 
included battery can be charged at a rate of up to 
3C (600mA).

Always disconnect the fl ight battery from the 
charger immediately upon completion of charging.

CAUTION:

 Overcharging a battery can cause 

a fi re.

CAUTION:

 Only use a charger specifi cally 

designed to charge this Li-Po battery. Failure to do 
so could result in fi re, causing injury or property 
damage.

CAUTION:

 Never exceed the recommended 

charge rate.
