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. assumes no liability in case of wrong usage or
operation of the product, respectively of all injuries.
The customer alone is in charge of the cell, this includes from
the recharging process up to the choice of place of use.
If the customer is not satisfied with the terms of usage, he
may use his right to return the unused product to the dealer.
Lithium-Polymer-Cells may only be stored and recharged, on fire-
proof 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-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 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 blan-
ket, 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 process
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) Order No. 17 0133.
Discharging temperature:
-20 to +60 degrees: Flying in winter is therefore possible. At tempe-
ratures beneath 0 degrees, it is likely that the capacity may be redu-
ced 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.
