SAFETY
ADVISORY NOTICE
I
Lithium-Polymer
(LiPo)
Batteries
]
LiPo batteries are differ from conventional batteries
in that their chemical contents are
encased
in a relatively insubstantial foil
packaging.
This has the advantage
of
significantly reducing their weight, but does
make them more susceptible to damage
if
roughly or
inappropriately handled. As with all batteries, there
is a risk of fire or
explosion if safety
practices
are ignored:
gt
Charge and store
LiPo batteries in a
location where a
battery
fire or explosion
(including
smoke hazard)
will not endanger life or
property.
M
Keep
LiPo batteries away from children and animals.
M
Consider how
you
would
deal
with a LiPo battery fire/explosior-r
as
part
of
your
normal home Fire Safety & Evacuation
Planning.
M
Never charge the LiPo battery that
has ballooned or swelled due to
over-/under-charging
or from a crash.
M
Nevercharge the LiPo batterythat
has been
punctured
or damaged in a crash
(After
a crash,
inspect the battery
pack
for the sign of damage.
Discard in
accordance
with
your
country's
recycling laws.).
M
Never charge the
LiPo battery in a moving
vehicle.
M
Never
over
charge the LiPo battery.
fl
Never
leave
the
LiPo battery unattended during recharging.
g
Do not charge
LiPo
batteries
near flammable materials or
liquids.
M
Ensure that charging leads are connected
correctly. Reverse
polarity
charging can
lead to battery damage
or a fire or explosion.
M
Have a
suitable fire extinguisher(electrical type) OR
a large bucket of dry sand near
the charging area . Do
not
try to
extinguish electrical
(LiPo)
battery
fires with water.
EI
Reduce risks from fire/explosion by storing
and charging LiPo batteries
inside
a
suitable container: a
LiPo Sack or metal/ceramic container
is advised.
M
Monitor recharging LiPo batteries
for signs of overheating.
M
Protect
your
LiPo
battery
from accidental damage during storage and
transportation.
(Do
not
put
battery
packs
in
pockets
or bags
where
they
can short
circuit or can come
into contact with sharp or
metallic objects.).
Bt
lf
your
LiPo battery
is
subjected
to a shock
(such
as
a helicopter crash)
you
should
place
it in a metal container and observe
for
signs
of swelling or heating
for at least
30 minutes.
M
Do
not attempt to disassemble or
modify or repair the
LiPo battery.
2.3 Prevent
Moisture
R/C
models are
composed
of
many
precision
electrical
components.
Store
the battery
and
model
in a dry
area at
room temperature.
Exposure to
water
or
moisture
may cause
the
model to
malfunction
resulting
