flammable materials.
The Battery Charger (EFLUC1007) included with the Beast 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 Beast 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.
• 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.
• 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.

Low Voltage Cutoff (LVC)

When a Li-Po battery is discharged below 3V per cell, it will not hold a charge. The Beast ESC protects the
flight battery from over-discharge using Low Voltage Cutoff (LVC). Before the battery charge decreases too
much, LVC removes power supply from the motor. Power to the motor pulses, showing that some battery
power is reserved for flight control and safe landing.
When the motor pulses, please land the aircraft immediately and recharge the flight battery.
Note: Due to the quiet nature of the aircraft, you may not hear the pulsing of the motor. Set flight timer to 5
minutes for 120mAh batteries and 7 minutes for 180mAh.
Disconnect and remove the Li-Po battery from the aircraft after use to prevent trickle discharge. Please
fully charge and store a Li-Po battery. During storage make sure battery charge does not go below 3V per
cell.
