The Battery Charging Process
1. 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.
2. Attach the input cord of the charger to the appropriate power supply (12V accessory outlet).
3. When the Li-Po charger has been correctly powered up, there will be an approximate 3-second delay, then an
audible “beep” and the green (ready) LED will flash.
4. Turn the control on the Amps selector so the arrow points to the charging rate required for the Battery (see chart,
for example the Extra 300’s 2200mAh Li-Po battery will charge at 2.0 amps). DO NOT change the charge rate once
the battery begins charging.
5. Move the cell selector switch to 2-cell or 3-cell for your battery.
6. Connect the Balancing Lead of the Battery to the 2-cell (it has three (3) pins) or 3-cell (it has four (4) pins) Charger
port.
7. The green and red LEDs may flash during the charging process, when the charger is balancing cells. Balancing
prolongs the life of the battery.
8. When the battery is fully charged, there will be an audible beep for about 3 seconds, and the green LED will shine
continuously.
9. Always unplug the battery from the charger immediately upon completion of charging.
CAUTION: Overcharging a battery can cause a fire.
Your Extra 300 comes with a DC balancing charger and 3S Li-Po
battery. You must charge the included Li-Po battery pack with a
Li-Po specific charger only (such as the included charger). Never
leave the battery and charger unattended during the charge
process. Failure to follow the instructions properly could result
in a fire. When charging, make certain the battery is on a heat-
resistant surface. It is recommended to charge the battery pack
while you are assembling the aircraft. The flight battery will be
required to confirm proper aircraft operation in future steps.

WARNING: Failure to use the proper charger for a Li-Po

long enough, will cause a fire. ALWAYS use caution when
charging Li-Po batteries.
WARNING: Selecting a charge rate higher than 1x (one
times) the battery capacity may cause a fire.
