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 (which is around 3.85V per cell) 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).
