ParkZone T-28 Trojan PNP PKZ4475 Data Sheet

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. 

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.

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. 

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.
