E-Flight has a responsibility as a battery supplier display these
warnings
for your information, they relate to ALL Lithium Polymer, Lithium Ion
(Li-Po, Li-Ion) cells currently available. The fact that a supplier of
Lithium Polymer, Lithium Ion does not label or warn of the dangers of
their
product does not make that product safe.
Under modelling discharge rates, the capacity of rechargeable Lithium
packs
or cells declines gradually, after 50 cycles it may be as low as
50%-80% of
a new pack.
E-Flight is unable to ensure that the correct charging regime is
applied
to this product, once the cells have been charged/discharged we cannot
accept any claim under our normal guarantee.
Please read these instructions & disclaimer carefully, they will also
be
supplied with any cells or packs purchased from e-flight, they must
also
be passed to any new owner should the cells or packs be sold.
Misuse of these cells can & will lead to explosions, fire, smoke & risk
of
poisoning.
Please note Li-Poly battery must be charged with a dedicated Lithium
charger. Buyer understands there are risks, known and yet unknown, to
the
use of Li-Poly battery in RC hobby.
- Only use chargers designed specifically for Lithium Polymer battery.
- Double check the charger, number of cell selection setting, and mAh
before every charge.
- Only charge the batteries on a non-flammable non-conducting surface,
such
as bare cement floor.
- Do not charge the battery inside the model plane, inside of ones
car,
home furniture or wood floor/carpet, or anywhere near flammable
material.
- Monitor the charging of the battery pack at all times. Do not leave
the
battery unattended.
- Place a fire alarm above the Li-Poly battery charging location.
Follow
the fire alarm installation instructions.
- After a crash, inspect the battery pack for damage. Discard the pack
outdoors if there is any sign of damage.
- Store the pack fully charged in a cool and dry location and out of
reach
of children.
- Do not assemble packs in series into parallel packs, as mismatch
could
result in fire.
- Do not carry or leave Lithium Polymer/Ion with model fuels such as
Petrol/Gas or Methanol
- Do not store Lithium Polymer battery inside a car.
- Do not short the battery as it may catch on fire. If you
accidentally
short a battery, place it in open space and observe the battery for 10
minutes. It may swell up and possibly even catch on fire.
- Do not discharge Lithium Polymer battery below voltage according to
the
number of cells in series in the following chart.
Before charging, your Lithium Polymer should have this minimum voltage.
Check battery pack voltage before charging
S = Series, P = Parallel
Minimum voltage
1 Cell 1SXP = 3.0V
2 Cells in series 2SXP = 6.0V
3 Cells in series 3SXP = 9.0V
4 Cells in series 4SXP = 12.0V
Check your charger for safety. After charging, check battery with a
digital
voltmeter, voltage should read between Min and Max:
Full charged pack should voltage between these numbers:
Minimum full charge to Maximum full charge
1 Cell = 4.16V to 4.23V
2 Cells in series = 8.32V to 8.45V
3 Cells in series = 12.48V to 12.68V
4 Cells in series = 16.64V to 16.9v
Maximum discharge: Do not discharge your Lithium Polymer battery below
the
voltage listed below, no load and load voltage.
Max Discharge Voltage for Li-poly cells and packs
No Load (Motor not running)/Loaded (Motor running)
1 Cell = 3.0V/2.5V
2 Cells in series = 6.0V/5.0V
3 Cells in series = 9.0V/7.5V
4 Cells in series = 12.0V/10.0V
There may be a slight chance the battery pack could combust due to
unmatched
cells in capacity or voltage, damaged cells, charger failure, charger
setting errors or many other factors. By purchasing these products,
buyer
understands the risk associated with the use of this experimental
product,
and will take the necessary precaution for its safe use and hold the
manufacturer, seller, all affiliates and agents harmless in case of
damage,
injury or death. Buyer is solely responsible for any damage or injury
resulting from the use of this experimental product. There is no
warranty
implied or expressed on Lithium Polymer battery and packs, as the
intended
use of these batteries in RC airplane application is beyond the design
specification of the manufacturer. By purchasing Lithium Polymer
battery
products, buyer fully understands the delicate nature of this battery
and
risk associated with this product, and agrees with the terms and
conditions
listed above.
