The Stinson Reliant E-Flite 30Amp ESC 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.
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 Stinson Reliant.
Note: 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.
Low Voltage Cutoff (LVC)
The Battery Charger included with the SR-10 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 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 you do
not agree with these conditions, return your complete SR-10
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 fire resulting in
personal injury and/or property damage.
• When flight battery balloons or swells, immediately remove
the battery from service.
• 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 flammable 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 fire.
• A battery that has ballooned or swollen even a small amount
must be removed from use immediately.
• 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 fire.
• Li-Po cells should not be discharged to below 3V each under
load.
