Low Voltage Cutoff (LVC)
When a Li-Po battery is discharged below 3V per
cell, it will not hold a charge. The aircraft’s 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 quickly decreases
and increases, showing that some battery power is
reserved for fl ight control and safe landing.
When the motor power 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 the battery charge does not fall
below 3V per cell.
For your fi rst fl ights, set your transmitter timer or a
stopwatch to 5 minutes. Adjust your timer for longer
or shorter fl ights once you have fl own the model.
Flights of 6 minutes or more are achievable if using
proper throttle management.
NOTICE:
Repeated fl ying to LVC will damage the
battery.
The USB battery charger (EFLC1008) included with
your aircraft has been designed to safely charge 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.
• NEVER LEAVE CHARGING BATTERIES
UNATTENDED.
• NEVER CHARGE BATTERIES OVERNIGHT.
• By handling, charging or using the included
Li-Po battery, you assume all risks associated
with lithium batteries.
• If at any time the battery begins to balloon or
swell, discontinue use immediately. If charging
or discharging, discontinue and disconnect.
Continuing to use, charge or discharge a battery
that is ballooning or swelling can result in fi re.
• Always store the battery at room temperature
in a dry area for best results.
• Always transport or temporarily store the
battery in a temperature range of 40–120º F
(5–49° C). Do not store the 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.
• Always charge batteries away from
fl ammable materials.
• Always inspect the battery before charging.
• Always disconnect the battery after charging,
and let the charger cool between charges.
• Always constantly monitor the temperature
of the battery pack while charging.
• ONLY USE A CHARGER SPECIFICALLY DESIGNED
TO CHARGE LI-PO BATTERIES. Failure to charge
the battery with a compatible charger may cause
a fi re resulting in personal injury and/or property
damage.
• Never discharge Li-Po cells to below 3V
under load.
• Never cover warning labels with hook and
loop strips.
• Never charge batteries outside
recommended levels.
• Never charge damaged batteries.
• Never attempt to dismantle or alter the charger.
• Never allow minors to charge battery packs.
• Never charge batteries in extremely hot or
cold places (recommended between 40–120° F
or (5–49° C) or place in direct sunlight.
