E-flite Apprentice 15e RTF with DX5e Radio - Manual (Page 40)

40 E-flite Apprentice Assembly Manual
• 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 LiPo battery packs.
• Do not allow children to use LiPo 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.
Swollen Batteries
Immediately stop using or charging. If the battery is not warm
to the touch, move it to an open safe area and observe it for at
least 15 minutes. Be VERY CAREFUL when moving the batteries.
Do NOT put ANY pressure on the batteries or covering as this
may cause fire.
Additional Information & Guidelines
1. Battery temperature the best indicator for safety. The E-flite LiPo
battery’s temperature should never drop below 32 degrees
Fahrenheit or go above 130 degrees Fahrenheit while charging
or discharging.
2. Changing plugs is NOT recommended as the process is
dangerous and any error can cause immediate fire. Improperly
installed plugs can also cause fire due to shorts, reverse polarity
or other improper handling which can cause battery damage.
3. Batteries should be stored in a vented, fire-resistant container.
Each pack should be stored in its own locked plastic bag within
the container. The number of battery packs per container
should be extremely limited to avoid chain reactions. Storage
temperatures should not fall below 32 degrees F or above
130 degrees F. Damaged batteries must be kept at even more
ambient temperatures. High temperatures may cause fire even
with undamaged batteries.
Battery Disposal
LiPo batteries require special handling for safe disposal. The
following are basic instructions for safe disposal. For more
