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.
