Lithium Polymer
Charging, Handling, Safety Information
Charging:
Lithium Polymer batteries have specific charging
requirements and ONLY chargers designed to charge Lithium Polymer batteries may
be used. The best chargers require the user to manually select the cell count
and charge rate for each pack, then automatically check to see that the settings
are correct. The Lithium Polymer Chargers that are sold by Servo Hut are
designed for this purpose. Chargers which use only automatic detection of cell
count (charge voltage) are prone to error, and can damage cells or cause a fire
due to over charging of cells by exceeding the cell voltage. We do not recommend
this type of charger. Other chargers are set manually, but do not include a
safety circuit to oversee that setting. These are prone to user error so we do
not recommend those chargers. Please do not charge your lithium polymer at any
rate higher than 1C. Doing so may reduce the capacity and life cycle of the
cells, with very little savings in charge time. Safety precautions for charging
Lithium Polymer batteries include:
- Check and re-check the Lithium Polymer
charger settings for the battery pack being charged - both voltage and
current settings
- Charge batteries on a surface that can
withstand heat and is not prone to catch fire. A wooden table is not
recommend.
- Do not charge batteries near flammable
items or liquids.
- Do not charge inside your model. The
materials used in model airplanes are highly flammable and or temperature
sensitive.
- Do not charge inside an automobile,
especially while driving.
- Do not use water to extinguish a battery
fire. Keep a dry fire extinguisher (class ABC is good) nearby. Do not try to
fight any fire. If you cannot stop a fire immediately, call the fire
department.
- Do not charge a battery that appears to
have "ballooned" due to over or under charging.
- Do not store batteries in an automobile.
- BATTERIES SHOULD NEVER BE LEFT UNATTENDED
WHILE CHARGING.
Handling:
New cells may have a high initial charge, and
care must always be taken to insure that single cells are not
short-circuited.
Please:
- Do not put the single cells in a pocket,
bag, or drawer where they could short-circuit against other items, or the
battery tabs could be pressed against each other.
- Do not place the single cells on any
conductive surface, such as a metal-topped table.
- Keep single cells and battery packs WELL
out of reach of children!
- Take care that especially metallic objects
like knives or scissors do not puncture the cells.
- If the electrolyte in the cells should get
on your skin, thoroughly wash with soap and water. If in the eyes, rinse
thoroughly with cool water. Immediately seek medical attention for this.
Warnings:
- Misuse of the battery may result in the
battery generating heat, exploding or igniting.
- Do not dispose in fire or heat.
- Do not immerse the battery in water or sea
water or allow it to get wet.
- Do not use the battery with the positive
and negative terminals reversed.
- Do not short circuit the battery.· Do not
pierce the battery with nails, strike the battery with a hammer or subject
it to other strong shocks.
- Do not directly solder the battery.
- Do not disassemble or modify the battery.
Do not disassemble or modify the battery.
- Do not place the battery in or near fires,
stoves or other high temperature locations.
- Do not use or store the battery inside cars
during hot weather. Doing so may cause the
battery to generate heat, explode or ignite. Using the battery in this
manner may also result in deterioration in performance and service life.
Warranty, Disclaimer And
Limitation of Liability as to Products Sold:
All sales of Lithium Polymer batteries are
now FINAL. This means we do not accept returns on
Lithium Polymer batteries for any reason. As used in R/C
applications discharge rates exceed the manufacturer's specified maximum
rates for these cells. Therefore, the use of Lithium Polymer batteries in
radio-controlled models is to be considered experimental, and there
is no warranty, expressed or implied, with respect to the capacity, life in
cycles, storage, or discharge characteristics of cells in RC use, nor any
other use nor aspect. We strongly suggest you use a safety guard component
with these cells. Lithium Polymer batteries hold a huge amount of energy and
must be respected. Since we cannot guarantee customers will follow the
proper safety precautions and use an appropriate well functioning charger
with the correct settings, we cannot accept any responsibility for the use
of Lithium Polymer battery products. Therefore, Servo Hut assumes no
responsibility for the use of Lithium Polymer battery products by our
customers. Your use of this product means you accept our terms and you are
fully responsible for any consequences.
