LIPO BATTERY WARNINGS AND USAGE GUIDELINES
WARNING: Lithium Polymer (LiPo) batteries are significantly more volatile than alkaline, NiCd or NiMH
batteries. All instructions and warnings must be followed exactly to prevent property damage and/or serious
injury as the mishandling of LiPo batteries can result in fire. By handling, charging or using the included LiPo
battery you assume all risks associated with LiPo batteries. If you do not agree with these conditions please
return the complete product in new, unused condition to the place of purchase immediately.
• You must always charge the LiPo battery in a safe, well-ventilated area away from ammable materials.
• Never charge the LiPo battery unattended at any time. When charging the battery you must always remain
in constant observation to monitor the charging process and react immediately to any potential problems that
may occur.
• After ying/discharging the LiPo battery you must allow it to cool to ambient/room temperature before
recharging.
• To charge the LiPo battery you must use only the included charger or a suitably compatible LiPo battery char-
ger. Failure to do so may result in a re causing property damage and/or serious injury.
• If at any time the LiPo 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 ammable 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 re. A battery that has ballooned or swollen even a small amount must be removed from service
completely.
• Do not over-discharge the LiPo battery. Discharging the battery too low can cause damage to the battery
resulting in
reduced power, ight duration or failure of the battery entirely. LiPo cells should not be discharged to below
3.0V each under load.
• Store the LiPo battery at room temperature and in a dry area for best results.
• When charging, transporting or temporarily storing the LiPo battery the temperature range should be from
approximately 40–120° F (5–49° C). Do not store the battery or aircraft in a hot garage, car or direct sunlight. If
stored in a hot garage or car the battery can be damaged or even catch re.
• Never leave batteries, chargers and power supplies unattended during use.
• Never attempt to charge low voltage, ballooned/swollen, damaged or wet batteries.
• Never allow children under 14 years of age to charge batteries.
• Never charge a battery if any of the wire leads have been damaged or shorted.
• Never attempt to disassemble the battery, charger or power supply.
• Never drop batteries, chargers or power supplies.
• Always inspect the battery, charger and power supply before charging.
• Always ensure correct polarity before connecting batteries, chargers and power supplies.
• Always disconnect the battery after charging.
• Always terminate all processes if the battery, charger or power supply malfunctions.
IMPORTANT NOTE: It’s safer and better for the longevity of the battery to store it only partially charged for
any length of time. Storing the battery approximately 50% charged is typically best, however, it will take some
careful management of the charge time and the use of a volt meter to achieve this voltage. If you have the equip-
ment and skills to achieve the 50% charge level for storage it is recommended. If not, simply be sure to not store
the battery fully charged whenever possible.
In fact, as long as the battery will be stored at approximately room temperature and for no more than a few
weeks before the next use, it may be best to store the battery in the discharged state after the last ight (as long
as the battery was not over-discharged on the last ight).
