Your aircraft comes with a 1S 3.7V DC Li-Po
battery charger and 1S 3.7V 150mAh 25C Li-Po
battery. Refer to the charging warnings. It is
recommended to charge the battery pack while
you are inspecting the aircraft. The fl ight
battery will be required to confi rm proper
aircraft operation in future steps.
Remove the cover on the bottom of the charger
and install four of the included AA batteries, noting
proper polarity. Replace the cover after the AA
batteries are installed. Only use alkaline AA
batteries.
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. Slide the battery into the slot on the charger
and press it into the charge jack/connector
located at the bottom of the slot.
The end cap of the battery is specifically
designed to allow the battery to fit into the
slot one way (usually with the label on the
battery facing outward) to prevent reverse
polarity connection. However, check for proper
alignment and polarity.
2. Always disconnect the flight battery from the
charger immediately upon completion of
charging.
CAUTION: Only use a charger specifi cally
designed to charge a Li-Po battery. Failure to do so
could result in fi re, causing injury or property
damage.
CAUTION: Never exceed the recommended
charge rate.
LED Indications
When you make the connection successfully, the
LED on the charger turns solid red, indicating
charging has begun.
Charging a fully discharged (not over-discharged)
150mAh battery takes approximately 30–40
minutes. As the battery nears full charge, the LED
begins to blink. The intervals between blinks will
increase as the battery comes closer to full charge.
When the LED blinks approximately every 20
seconds, the battery is ready to be removed.
However, the battery can be left charging until the
LED completely goes out for a maximum charge.

Purchase the optional AC to 6V DC 1.5 amp
Power Supply (EFLC1005) to charge your
battery pack without AA batteries.
CAUTION: Only use an E-fl ite ® 6V power
supply (EFLC1005) with this charger. DO NOT
use a 12V power supply or property damage
and injury could occur.
If the LED stays on when the fl ight battery is
removed, the AA batteries in the charger are low.
CAUTION: Once charging is complete,
immediately remove the battery. Never leave a
battery connected to the charger.
