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
flammable 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 flying/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 charger. Failure to do so may result in a fire 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 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.
• Do not over-discharge the LiPo battery. Discharging the battery too low can cause
damage to the battery resulting in
reduced power, flight 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 fire.
• 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 equipment 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 flight (as long as the battery was not over-discharged on the
last flight).
