GB - Instructions for the use of Lithium Batteries
Important Notice
Read the manual and the safety precautions for the Lithium-Cells
properly.
- Litium-Cells have no memory-effect.
- Lithium-Cells are recharged with a constant voltage and a
constant power.
- Lithium-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-Cells may only be stored and recharged, on fireproof
non-flamable grounds. Jamara e.K. recommends to recharge
the cells only with the transmitter. When using an other charger
or when using the permitted charger incorrect, no liability can be
taken. Because of their enormous power-compactivity Lithium-
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 checked carefully.
For example the cell/pack could have been damaged, 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 level
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. Charge with max. 1°C = 1.5 A. Charging
voltage per cell are 4.2 V.
Charging temperature:
0 to +45 degrees outside temperature. During charge, the bat -
tery should not get warmer than 70 °C. Supervise the charging
process with help of the JAMARA Thermo Scan 300 ( Non-touch
infrared thermometer) 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.
