2b. If using a discharger, connect the battery’s

discharge connector to the discharger’s
main output. Connect the battery’s
balancing connector to the discharger’s
balancing port. Read the discharger’s
instructions entirely before use.

NEVER allow a battery to discharge
below 2.5 volts per cell at any time. Do

not discharge the battery at currents
exceeding the maximum “C” rating shown
on the battery’s label. Failure to follow
these warnings can result in the battery
overheating and failing. Do not allow a
LiPo cell to exceed 140°F (60°C) during
discharge.

BATTERIES INVOLVED IN A CRASH

LiPo batteries involved in a crash can be
dangerous. Even if no physical damage is
visible, a delayed chemical reaction could
cause the battery to ignite even after having
been removed from the crash for some time.
After a crash, place the battery in a fi reproof
location IF SAFE TO DO SO, and observe for

at least 30 minutes. Carefully inspect it for
cracks, splits, punctures, etc. Do not continue
to use damaged batteries. Refer to the

DISPOSAL OF LIPO BATTERIES section at
the end of this manual.

CAUTION! Cells may be hot! DO
NOT allow the battery’s internal
electrolyte to get in the eyes or on

skin. Wash affected areas with soap and water
immediately if they come in contact with the
electrolyte. If electrolyte makes contact with
the eyes fl ush with large amounts of water
for 15 minutes and seek medical attention
immediately. If a battery leaks electrolyte or
gas vapors, do not inhale leaked material.
Leave the area and allow the batteries to cool
and the vapors to dissipate. Remove spilled
liquid with absorbent and dispose.

OTHER SAFETY PRECAUTIONS

● NEVER allow LiPo batteries to be charged

or discharged on or near combustible
materials, including paper, plastic, carpets,
vinyl, leather, wood, inside an R/C model or
full-sized automobile.

● NEVER put packs in the pocket of any

clothing.

● NEVER allow LiPo cells to come in contact

with moisture or water at any time.

● NEVER store batteries near an open fl ame

or heater.

● NEVER assemble LiPo cells or pre-

assembled packs together with other LiPo
cells/packs. Only a qualifi ed battery assembly
company should assemble or modify LiPo
batteries.

● NEVER allow LiPo cells to become

punctured, especially by metallic objects
such as screwdrivers, T-pins, or hobby knives.

● ALWAYS provide adequate ventilation

around LiPo batteries during charge,
discharge, and during storage. If a battery
becomes overheated IMMEDIATELY place it
in a fi re-proof location until it cools.

● ALWAYS store LiPo cells/packs in a

secure location away from children.

● ALWAYS make sure that metallic objects,

such as wristwatches, bracelets, or rings are
removed from your hands when handling
LiPo packs. Accidentally touching battery
terminals to any such objects could create
a short-circuit condition and possibly cause
severe personal injury.

STORAGE AND TRANSPORTATION

● For long term storage, it’s recommended

to charge the cells fully, then discharge them
to a 50-60% of their rated capacity.

● Store battery at room temperature in a

cool or shaded area, ideally between 40-80ºF.

Temperatures exceeding 170ºF for greater

than 1 hour may cause damage to the battery
and cause a fi re.

● Do not expose battery packs to direct

sunlight for extended periods of time, or place
in a direct contact with any liquids. If batteries
come in contact with water, immediately dry
the battery with a clean towel.

● When transporting LiPo batteries, store

them in a fi reproof container. NEVER leave
batteries lying loosely anywhere in the car

(in the trunk, backseat, fl oor, etc.).

● ALWAYS make sure all plugs / connectors

on the LiPo battery are covered, to prevent
an accidental short. Small sections of fuel
tubing make good insulators.

● NEVER leave LiPo batteries in the car

indefi nitely as temperatures inside the vehicle
can easily rise far in excess of 120ºF which
could damage the battery.

DISPOSAL OF LIPO BATTERIES

Lithium-polymer batteries are environmen-
tally friendly. For safety reasons LiPo cells
should be fully discharged before disposal

(however, if physically damaged it is NOT

recommended to discharge LiPo cells before
disposal - see below for details). The bat-
teries must also be cool before proceeding
with disposal instructions. To dispose of
LiPo cells and packs:

1. Place the LiPo battery in a fireproof

container or bucket of sand.

2. If any LiPo cell in the pack has been

physically damaged, resulting in a swollen
cell or a split or tear in a cell’s foil covering,
do NOT discharge the battery. Jump to
step 5.

3. Connect the battery to a LiPo discharger.

Set the discharge cutoff voltage to the
lowest possible value, and the current
as low as 20mA if possible. It’s also
possible to discharge the battery by
connecting it to an ESC/motor system
and allowing the motor to run indefinitely
until no power remains to further cause
the system to function.

4. Discharge the battery until its voltage

reaches 1.0V per cell or lower.

5. Disconnect the battery, and submerse it

into a bucket or tub of salt water. This
container should have a lid, but it does not
need to be air-tight. Prepare a bucket or
tub containing 3 to 5 gallons of cold water,
and mix in 1/2 cup of salt per gallon of

water. Drop the battery into the salt water.
Allow the battery to remain in the tub of
salt water for at least 2 weeks.

6. Remove the LiPo battery from the salt

water and place it in the normal trash.
