Battery Warnings and Guidelines

The included battery charger (EFLC1000) has been designed to safely charge the included
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 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 (4.44–48.88º
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 damaged batteries.
• 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 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.
• N ever charge batteries in extremely hot or cold places (recommended between 40–120° F or
4.44–48.88° C) or place in direct sunlight.

Low Voltage Cutoff (LVC)

When a Li-Po battery is discharged below 3V, the battery may be damaged and may no longer accept
a charge. The mCX2's 5-in-1 control unit 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 decreases and the LED on the 5-in-1 control unit blinks, showing some
battery power is reserved for flight control and safe landing.
When the motor power decreases, please land the aircraft immediately and recharge the flight battery.
Disconnect and remove the Li-Po battery from the aircraft after use to prevent trickle discharge. Before
storage, charge the Li-Po battery to full capacity. During storage make sure the battery charge does
not go below 3V.
NOTICE: Repeated flying to LVC will damage the battery.
