Charging the Battery
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. 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.
3. Slide the battery into the slot on the charger. 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 before
proceeding to the next step.
4. Gently press the battery and its connector into the charge jack/connector located at the bottom of
the slot in the charger.
5. When you make the connection successfully, the LED on the charger turns solid red, indicating
charging has begun.
6. Charging a fully discharged (not over-discharged) 120mAh battery takes approximately 30–40
minutes. As the battery nears full charge, the LED begins to blink.
7. When the battery is fully charged, the LED blinks approximately every 20 seconds or goes out
entirely.
Note: If the LED stays on when the LiPo is removed, the AA batteries in the charger are low.
8. Always unplug the battery from the charger immediately upon completion of charging.
CAUTION:
Overcharging a battery can cause a fire.
WARNING:
Failure to use the proper charger for a Li-Po battery can result in serious damage,
and if left charging long enough, will cause a fi re. ALWAYS use caution when charging
Li-Po batteries.
WARNING:
Selecting a charge rate higher than 1x (one times) the battery capacity on a
variable rate charger may cause a fi re.
Your T-28 comes with 1S 3.7V Li-Po Battery
Charger and 1S Li-Po battery. It is important
that you only charge with the included
charger, or the E-fl ite® Celectra™ 4-port
Charger (EFLC1004). Refer to page 4. It is
recommended to charge the battery pack
while you are assembling the aircraft. The
fl ight battery will be required to confi rm
proper aircraft operation in future steps.
