Warnings and Safely Instructions
You must read and follow
our safety instructions and warnings before using or charging your Lithium Polymer
batteries. Failure to read and follow the instructions may result in fire, personal
injury, and damage to property. In purchasing Lithium Polymer batteries from
BatteryPrice the buyer/user agrees to accept all responsibilities of these risks
and not to hold BatteryPrice, its Distributors and Retailers (owners and employees)
responsible for any accidents, injury to persons, or property damage. Since
many Radio-Controlled and Airsoft applications exceed cell manufacturers
recommended maximum discharge rates, there is no warranty (expressed or implied)
by the manufacturer, its Distributor and Retailers in the respect to the Life
Cycle, Capacity, Cell Characteristics or Storage of cells/packs used in the
Radio-Controlled or Airsoft market. By purchasing this battery, the buyer/user
assumes all risks associated with Lithium Polymer batteries. If you do not agree
with these conditions, return the battery to the store where you purchased for
a refund/exchange before using.
(herein referred to as Li-Po) cells have very strict charging requirements.
As a result, please always charge Li-Po batteries with the recommended Protection
Circuit Module (herein referred to as PCM) or great damage may occur. You can
purchase the PCM from your retail hobby shops.
You should only use approved
Li-Po chargers and never ever use a NiMH or NiCd chargers to charge Li-Po. Failure
to do so may cause a fire which can result in personal injury and property damage.
Please note that even though some cheap chargers indicate that they can charge
Li-Po, it is not safe to do so. You should invest in a quality reputable Li-Po
specific charger. Never leave Li-Po charging unattended. You should always monitor
the charging process of your Li-Po so that you can react immediately to any
potential problems that may occur. If your batteries start to balloon or swell
up, discontinue charging immediately and follow disposal notice below. Before
and after every use of your Li-Po batteries, inspect them to ensure that there
is no physical damage or swelling as those are signs of imminent failure. You
should also have your chargers inspected annually by its manufacturer to ensure
that it is functioning properly. You should always buy factory authorized built
packs instead of building your own. If you attempt to build your own, please
use extreme care and have a dry fire extinguisher handy.
Always observe the correct
polarity when connecting cells or packs to charger or application.
Preparation for charging:
When you receive
your order from us, please read all instruction and inspect all battery packs.
If there is any physical damage or puncture, contact us before attempting to
use. Always install proper connector immediately after you remove the protective
caps on the wire lead. Remove one protective cap and solder that lead to the
connector first then follow the same procedure for the next wire lead. Be careful
not to short the wire lead. If you accidentally cause the battery to short circuit,
place it in a safe open space and observe the battery for approximately 15 minutes.
If utilizing the
recommended PCM, never disconnect the battery from the PCM while still charging.
Wait for the battery to be charged prior to disconnecting. If you sense there
is a problem during the charging cycle, power off the charger or disconnect
the PCM from the charger then address the problem. Not doing so can destroy
the PCM Guard
To prevent possible fire damage, it is recommended that you charge your Li-Po
batteries outdoors in a fire proof container. Set voltage and current correctly
to ensure that your battery will get a full charge. The charge voltage should
equal the number of cells times 4.2V per cell and the current should match the
capacity of the pack (or lower). Do not charge your Li-Po battery above 1C (1
x capacity). Your charger should complete charging your battery packs within
one hour. Do not attempt to charge your battery if they are wired in parallel.
Doing so will increase the risk of potential fire hazard and void all warranty.
You should ONLY charge each battery pack individually through the PCM plug utilizing
the PCM Guard.
Keep run time short in multiple sessions to ensure a long life cycle. Do
not exceed the rated C rating or damage can occur. If you need to exceed the
C rating (i.e. take off, acrobatic stunts, etc.), keep the pulse short and no
more than 10 seconds. Allow for airflow over the pack in any application. This
will prolong the life of the battery. Do not discharge battery to a level below
3V per cell under load. Deep discharge below 3V per cell can deteriorate life
cycle and ruin your battery.
Storage & Transportation:
Store battery at room temperature in cool or shaded area. Do not expose battery
packs to direct sunlight or in direct contact with any liquids. If theres
water contact, remove battery packs immediately and wipe them off with a clean
towel. Store battery
in a safe container while driving. If keeping the battery in the car while driving,
remove them immediately after you stop. You should never leave your battery
packs in the trunk or in the car unattended as the temperatures can exceed 90F
easily causing potential damage.
Life cycle of your battery depends on the extent of your C usage. The higher
current you subject your Li-Po battery to, the shorter life cycle you will get.
If your batteries lose 20% or more of their rated capacity, you should discontinue
using the battery and follow disposal instruction below.
Damaged cells or packs:
In the event that your Li-Po batteries were involved in a crash, inspect the
cells, wire leads, and connections for possible short circuit. If any cells
are dented or deformed, theres a possibility of cells damage. If in doubt,
destroy the battery, as your safety is more important than a damaged battery.
Follow disposal instructions below.
Charge cycle: 32 to 120 degrees F
Discharge cycle: 32 to 140 degrees F
After use, let the battery
cool down to room temperature before charging. If the battery becomes increasingly
hot, stop charging or discharging immediately by shutting down your charger
first; then restart only when it is safe to do so. Do not leave battery packs
inside your car as extreme temperature could cause the battery to swell up and
combust into flame.
Discharge all cells individually to 3.0 volts per cell. The cells or packs may
be warm or hot during this discharge process (see above). After cooling, insulate
the output terminals and dispose of your battery immediately.
Additional safety guidelines:
If you come in contact with electrolyte, scrub with soap and water immediately.
In the event that electrolyte gets in your eyes, flush with cold water and seek
medical attention immediately. And as always, keep all batteries and radio control
equipment out of reach of children.
Product warranty is limited to original manufacturers defects in material
and workmanship. Warranty does not cover collateral damage such as personal
and property damage.
