Low Voltage Cutoff (LVC)

The Extra 300 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 flying 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 flight duration during subsequent flights, 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 flight controls do not respond
to the transmitter.

Charging Warnings

CAUTION: All instructions and warnings must be
followed exactly. Mishandling of Li-Po batteries can result in a
fire, 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 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 fire.
• 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 (4–49º C). Do not store
battery or aircraft in a car or direct sunlight. If stored in a
hot car, the battery can be damaged or even catch fire.
• Always charge batteries away from flammable materials.
• Always inspect the battery before charging and never
charge dead or damaged batteries.
• Always disconnect the battery after charging, and let the
charger cool between charges.

Stay aware of the power level of the battery/aircraft
throughout the flight, and, when the aircraft requires more
throttle than typical, immediately land the Extra 300.
Battery performance is reduced in cooler temperatures. It is
recommended the batteries are warm before flight.
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.
ONLY
®
• 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 fire 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 leave charging batteries unattended.
• Never charge batteries outside recommended levels.
• 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 4–49° C) or place
in direct sunlight.
CAUTION: Always disconnect the Li-Po battery from the
aircraft receiver when not flying to avoid over-discharging
the battery. Batteries discharged to a voltage lower than the
lowest approved voltage may become damaged, resulting in
loss of performance and potential fire when batteries are
charged.
