Charging the Flight Battery

Your T-28 comes with a DC balancing charger and 3S Li-Po battery. You should
only charge your battery with the included charger. Never leave the battery and
charger unattended during the charge process. Failure to follow the instructions
properly could result in a fi re. When charging, make sure the battery is on a
heat-resistant surface. Charge the fl ight battery while assembling the aircraft.
Install the fully charged battery to perform control tests and binding.

The Battery Charging Process

1. Charge only batteries that are cool to the touch and are not damaged. Look at the battery to ensure 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 fl ash.
4. Turn the control on the Amps selector so the arrow points to the charging rate required for the battery (the T-28's included 1800mAh 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 3-cell for your battery.
6. Connect the Balancing Lead of the battery to the 3-cell (it has 4 pins) charger port.
7. Press the Start button to begin charging the battery. The green and red LEDs may fl ash 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. Attempting to charge
an over-discharged battery will cause the charger to repeatedly fl ash 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 fi re.
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.

Low Voltage Cutoff (LVC)

When a Li-Po battery is discharged below 3V per cell, it will not hold a charge.
The ESC protects the fl ight battery from over-discharge using Low Voltage
Cutoff (LVC). Before the battery charge decreases too much, LVC removes
power supplied to the motor. Power to the motor pulses, showing that some
battery power is reserved for fl ight control and safe landing.

3S 11.1V 1800mAh Li-Po Battery Pack (PKZ1031)
The ParkZone ® 3S Li-Po battery pack features a balancing lead that allows
you to safely charge your battery pack when used with the included ParkZone
Li-Po balancing charger.
CAUTION: The balance connector must be inserted into the correct port
of your charger prior to charging.
NOTICE: If using a battery other than the included Li-Po battery, refer to your
battery manufacturer's instructions for charging.
When the motor pulses, land the aircraft immediately and recharge the
fl ight battery.
Disconnect and remove the Li-Po battery from the aircraft after use to prevent
trickle discharge. Fully charge your Li-Po battery before storing it. During
storage, make sure battery charge does not fall below 3V per cell.
