WARNING!! NEVER enter a discharge cutoff voltage
value into the discharger or ESC that is lower than
the value specifi ed for the battery! Failure to follow
this warning can cause permanent damage to the battery and
might result in a FIRE when attempting to recharge the battery
afterwards!!! Do not discharge LiPo batteries at currents that
exceed the maximum rating of the pack, as overheating could
occur. Do not allow a LiPo to exceed 140°F (60°C) during discharge.
Batteries Involved in a Crash
Carefully inspect a LiPo battery which has been involved in a crash
to determine that no physical damage has occurred. Look for even
the smallest of cracks, splits, punctures, or damage to the wiring
and connectors. Failure to do so could result in a battery failing
at some point afterward, resulting in a total loss of power in the
battery or even a FIRE. It’s possible that sometime after removing
it from a crash a LiPo battery might begin to smolder, emit smoke
and catch fi re even after 30 minutes or an hour. Remove the LiPo
battery from the crashed model but DO NOT immediately place
it in a model, full size automobile, pocket, pit bag, etc. Place the
battery in a fi reproof location instead, for up to 24 hours if possible,
and observe it for safety reasons.
CAUTION: Cells may be hot! Refer to the following section for
important handling and fi rst aid instructions.
Handling & First Aid Instructions
■ NEVER put loose cells or 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 assembler
should assemble or modify LiPo battery packs.
■ NEVER allow LiPo cells to become punctured, especially by
metallic objects such as screwdrivers, T-pins, or hobby knives.
■ DO NOT allow the battery’s internal electrolyte to get in the
eyes or on skin. Wash aff ected 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
an absorbent material and dispose.
■ 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.
■ LiPo batteries are environmentally friendly. For safety
reasons, it’s best that LiPo cells be fully discharged
before disposal (however, if physically damaged it is NOT
recommended to discharge LiPo cells before disposal - see
below for details). Allow batteries to cool before proceeding
with disposal instructions.
Storage and Transportation
■ For long term storage it is recommended to charge the cells
fully, then discharge them to 50-60% of their capacity.
■ Store batteries at room temperature in a cool or shaded area,
ideally between 40-80°F.
■ NEVER allow LiPo batteries to freeze. This will damage the cells
and reduce performance.
■ Do not expose battery packs to direct sunlight for extended
periods of time, or place in direct contact with any liquids. If
batteries come in contact with water, immediately dry the
battery with a clean towel.
■ Transport LiPo batteries in a fi reproof container. NEVER leave
batteries lying loosely anywhere in the car (in the trunk,
backseat, fl oor, etc.). NEVER leave LiPo batteries in the car
indefi nitely as temperatures inside the vehicle can easily rise
far in excess of 120°F which could damage the battery.
■ 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.
Disposal of LiPo Batteries
To dispose of LiPo cells and packs:
1. 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.
2. Place the LiPo battery in a fireproof container or bucket
of sand.
3. Connect the battery to a LiPo discharger. Set the discharge
cutoff voltage to the lowest possible value. Set the discharge
current to a C/10 value. For example, a battery rated at
1200mAh has a “C/10” rating of 0.12 amps, or 120mAh….
calculated as [(1200 divided by 1000) divided by 10] = 0.12A. As
an alternative, a battery can also be discharged by connecting
it to an ESC/motor system and allowing the motor to run
indefi nitely 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. Submerse the battery into bucket or tub of salt water. This
container should have a lid, but it does not need to be airtight.
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.
