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 ope-
rating and user instructions, it contains important informati-
on 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 over-
charging, 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. vib-
rations) 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 degrees outside temperature. During charge, the battery
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 storing
empty cells will lead to their destruction. New cells are therefore
half full.
