GB - Instructions for the use of LiPo Batteries
Important Notice
Read the manual and the safety precautions for the
Lithium-Polymer-Cells properly.
- Litium-Polymer-Cells have no memory-effect
- Lithium-Polymer-Cells are recharged with a constant voltage
and a constant power
- Lithium-Polymer-Cells have a small self-discharging Voltage
Liability exclusion
Jamara e.K. is not liable for any damage caused to the pro-
duct itself or through this, provided this is due to improper
operation or handling errors. The Customer alone bears the
full responsibility for the proper use and handling, including
without limitation, the assembly, the charging process, the
use and choice of the operation area. Please refer to the
operating and user instructions, it contains important infor-
mation and warnings.
Lithium-Polymer-Cells may only be stored and recharged, on
fireproof non-flamable grounds. Jamara e.K. recommends to re
-
charge the cells only with the transmitter. When using an other
charger or when using the permitted charger incorrect, no liabili-
ty can be taken. Because of their enormous power-compactivity
Lithium-Polymer-Cells are flameable when damaged. This can
happen through extrem overcharging, a crash or a mechanical
damage etc. Therefore, it is extremly important to supervise the
recharging process. After a crash the cell/pack should be che-
cked carefully. For example the cell/pack could have been da
-
maged, but does not heat up before 30 minutes. So, in case of a
damage at one pack or a cell always strictly supervise.
If the cell overheats, swells, burns or smoke is coming from
it, do not touch it under any circumstances. Keep away in
a safe distance and prepare adequate extinguishing agents
such (No water explosion, well dry sand, fire extinguishers,
fire blanket, salt water).
Safety precausions
Because of the high power compactivity (up to 150 Wh/kg) the
cells are quite dangerous and need special care! The company
Jamara excludes explicitly, all types of liability for damages, that
can occure when using the Lithium-Polymer-Cells indequate.
- When using the battery incorrect there is a risk of getting
fire- or acid-injuries.
- Overcharging, too high power, or discharging at low level
destroys the cell.
- Protect from mechanical stress (squeezing, pushing,
bending, drilling).
- Never open or cut open, do not throw into fire, keep away
from children.
- Handle damaged or leaking battery with care. Injuries or
damages to the product can occure.
- Under no circumstance short-circuit the device and always
watch out for correct polarity.
- Protect batteries from heat above 65 °C , mount away from
hot objects (for example exhaust pipe).
- Before storing batteries (for example in the winter) charge
the battery. Do not store in fully charged or in non charged
state!
- If stored over a longer period of time, observe the power l
evel occasionally.
- The contents of the cell is harmfull for skin and eye.
- If the content comes into contact with skin, clean with plenty
of water and take off moisted clothes.
- If the content comes into contact with the eyes, clean with
plenty of water and consult a doctor.
Technical data
Case:
The case of the cells consists of an aluminium-plasticfoil. This
foil should not be damaged under any circumstance, because
this will lead to a damaged cell. Take care of sufficient protection
(i.e. vibrations) in the model. If damaged, they might leak, avoid
contact under all circumstances.
Overcharging:
If charging does not stop because of any damage to the charger
the battery may catch fire. Therefore supervise the charging pro
-
cess frequently.
Speed charging:
Speed charging is not possible. The charging voltage for these
cells must be followed.
Charging temperature:
0° to +45°C outside temperature. During charge, the battery
should not get warmer than 70 °C. Supervise the charging pro-
cess with help of the JAMARA Thermo Scan 300 ( Non-touch
infrared thermometer) Order No. 17 0133.
Discharging temperature:
-20° to +40°C: Flying in winter is therefore possible. At
temperatures beneath 0 degrees, it is likely
that the capacity may be reduced by approx.
20% and the discharge level may be smaller
as well.
Lifetime:
Very user-dependent.
Storage:
The cells need to be between half full and full charged. The sto-
ring empty cells will lead to their destruction. New cells are there-
fore half full.
