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 (the 3200mAh Li-Po battery will charge at 3.0
amps). DO NOT change the charge rate once the battery begins charging.
5. Move the cell selector switch to 3-cell for your battery.
6. Connect the balancing lead of the battery to the 3-cell (4 pin) charger port and press the Start button to begin battery charging.
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, a beep will sound for about 3 seconds and the green LED will shine continuously. Attempting to charge an over-
discharged battery will cause the charger to repeatedly flash and beep, indicating an error has occurred.
9. Always unplug the battery from the charger immediately upon completion of charging.
CAUTION: Overcharging a battery can cause a fire.
CAUTION: Only use a charger specifically designed to charge a Li-Po battery. Failure to do so could result in fire causing injury or property damage.
CAUTION: Never exceed the recommended charge rate.
NOTICE: If using a battery other than the included Li-Po battery, refer to your battery manufacturer’s instructions for charging.
Your Apprentice S trainer 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, ensure the battery is on a heat-resistant
surface. Charge the battery pack while you are assembling the aircraft. You will
need the flight battery to confirm proper aircraft operation in future steps.
