The Battery Charger (PKZ3240) included with
the T-28 BNF has been designed to safely
charge the Li-Po battery. You must read the
following safety instructions and warnings
before handling, charging or using the Li-Po
battery.
CAUTION:
All instructions and warnings must
be followed exactly. Mishandling of Li-Po
batteries can result in a fi re, personal injury,
and/or property damage.
By handling, charging or using the
•
included Li-Po battery you assume all
risks associated with lithium batteries.
If you do not agree with these conditions,
return your complete T-28 model in new,
unused condition to the place of
purchase
immediately.
DO NOT USE A Ni-Cd OR Ni-MH
•
CHARGER. Failure to charge the battery
with a compatible charger may cause fi re
resulting in personal injury and/or
property
damage.
If at any time during the charge process
•
the battery begins to balloon or swell,
discontinue charging or discharging
immediately. Quickly and safely
disconnect the battery, then place it in
a safe area away from fl ammable
materials to observe it for at least 15
minutes. Continuing to charge or
discharge a battery that has begun to
balloon or swell can result in a fi re.
Store the battery at room temperature in
•
a dry area for best results.
When transporting or temporarily storing
•
the battery the temperature range should
be from 40–120º F. Do not store battery
or model in a car or direct sunlight.
If stored in a hot car, the battery can be
damaged or even catch fi re.
Li-Po cells should not be discharged to
•
below 3V each under load.
Battery Warnings
Low Voltage Cutoff (LVC)
The T-28 receiver features a soft low voltage
cutoff (LVC) that occurs when the battery
reaches 3V per cell under load. When the soft
cutoff occurs, the electronic speed control
(ESC) and receiver reduce power to the motor
(regardless of the power level set with the
throttle stick). This prevents the voltage of the
battery from dropping below 3V per cell.
While it is possible to continue fl ying the
aircraft after the soft LVC occurs, this is NOT
recommended. Battery discharge after LVC
will damage the Li-Po battery, resulting in
less power and shorter fl ight duration during
subsequent fl ights, or complete failure of
the battery.
Discharging the battery after low voltage
cutoff may result in loss of control. Battery
power may drop below the receiver’s
minimum operating voltage so fl ight controls
do not respond to the transmitter.
Stay aware of the power level of the battery/
aircraft throughout the fl ight, and when the
aircraft requires more throttle than typical,
immediately land the T-28.
Note:
Battery performance is reduced in
cooler temperatures.
CAUTION:
ALWAYS disconnect the battery
from the aircraft to prevent trickle discharge
of the battery. These batteries require
regular maintenance to keep them at a
usable charge level.
Never leave
charging Batteries
unattended.
Always charge
Batteries away from
flammable materials.
Never charge
Batteries outside safe
temperature range.
Never charge
Batteries outside
recommended levels.
Store
Batteries
safely.
Never charge
damaged Batteries.
