Usage Guidelines, Warnings and Safety Precautions
• Li-Po batteries may explode if damaged or if disposed
of improperly.
• Always inspect batteries before charging.
• Never charge or use a Li-Po battery or pack that shows
any damage or disfigurement of any kind. Swelling is a
sign of internal damage. Any breach of protective cover,
wiring or plugs is also reason to discontinue use (See
Disposal Instructions).
• Use specific Lithium Polymer charger only. Do not use a Ni-Cd
or Ni-MH charger – failure to do so may cause a fire, which
may result in personal injury and/or property damage.
• Never charge around or in the area of any flammable or
combustible materials.
• Always charge Li-Po batteries in or on fire resistant materials
or containers.
• Never leave battery and charger unattended while in use.
Improper charging or discharging of Li-Po batteries could
result in fire.
• Constantly monitor the temperature of the battery pack while
charging. If the battery becomes hot to the touch discontinue
charging immediately. Disconnect the battery from the charger
and observe it in a safe place for at least 15 minutes.
• If at any time you see a battery starting to balloon or swell up,
discontinue charging or using immediately.
• Lithium batteries can still ignite after at least 45 minutes
due to a delayed chemical reaction. If battery is damaged or
overheats, observe the battery in a safe area outside of any
building or vehicle and away from combustible material.
• Do not allow children to charge Li-Po battery packs.
• Do not allow children to use Li-Po batteries without
adult supervision.
• Shorting the wire leads can cause fire. If you accidentally
short the wires, the battery must be placed in a safe area for
observation for at least 15 minutes.
• Never store or charge a battery pack where the temperature
will go below 32 degrees Fahrenheit or above 130 degrees
Fahrenheit. Extreme temperatures will damage the battery pack
and may cause a fire. Battery performance may be diminished
by less extreme temperatures.
• Any of the following may cause the battery to be damaged
resulting in battery swelling, leaking, or fire:
• Bending, folding or dropping of the battery
• Damaging the edge seal of the battery
• Taking apart the battery
• Mixing cells of differing chemistry, or types, or sizes
• Mixing cells of different ages
Crash Damage
If there are signs of smoke or overheating, DO NOT go
near the battery or equipment until it has been observed from
a safe distance for at least 15 minutes. Once it is safe, remove
the battery and check for damage. Dispose of damaged
batteries appropriately.
