Battery Warnings, Guidelines and Charging (continued)
• You must charge the included 7.4V 800mAh 2-cell Li-Po battery pack in a safe area away from flammable
materials.
• Do not charge the battery when installed in the helicopter.
• Never charge the battery unattended. When charging the battery you should always remain in constant
observation to monitor the charging process and react to potential problems that may occur.
• After flight, the battery must be cooled to ambient temperature before charging.
• You MUST use the included 2-cell 7.4V Li-Po Balance Charger ONLY. Failure to do so may result in a fire
causing personal injury and/or property damage. DO NOT use a Ni-Cd or Ni-MH charger
.
• If at any time during the charge or discharge 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, open
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 service completely.
• In the event of a crash, you must quickly and safely disconnect and remove the battery from the model, then
place it in a safe, open area away from flammable materials to observe it for at least 15 minutes.
• Store the battery at room temperature for best results.
• When transporting or temporarily storing the battery, the temperature range should be from 40–120 degrees
Fahrenheit. Do not store the battery or model in a car or direct sunlight whenever possible. If stored in a hot
car, the battery can be damaged or even cause a fire.
• Do not over-discharge the battery. Discharging the battery too low can cause damage to the pack resulting in
reduced performance and duration. Follow the additional guidelines found in the “Flying the Blade CX” section
(page 25) to prevent over-discharge of the battery.
If you have any further questions or concerns regarding the handling, charging and/or use of the included Li-Po
