charge and discharge requirements.
•
LiPo batteries must not be thrown in a fi re or incinerated.
•
LiPo cells must not be allowed to come into contact with fl uids such as water, salt water or
drinks, even for a very short period. Avoid all contact with liquids of any type.
•
Individual cells and packs made up of cells are not playthings, and must not be allowed into
hands of children. Store batteries and cells well out of the reach of children.
•
Batteries must be kept out of the reach of babies and small children at all times. If a battery
should be swallowed, seek emergency medical attention immediately.
•
Batteries must not be placed in a microwave oven or subjected to pressure. This may result
in smoke and fi re or even worse.
•
Never dismantle a LiPo battery. Dismantling a pack may cause internal short-circuits, with
the possible results of gassing, fi re, explosion and other problems.
•
LiPo batteries contain toxic electrolytes and electrolyte vapours which are damaging to
health. Take great care to avoid direct contact with electrolyte. If electrolyte contacts your
skin, eyes or any other body part, immediately wash it off using plenty of clean water, then
consult a doctor.
The company of Graupner GmbH & Co. KG is unable to ensure that you use the correct me-
thods to charge and discharge these cells, and for this reason we are obliged to refute any
claim under guarantee if the cells have been charged or discharged incorrectly.
Additional notes on handling LiPo batteries
•
For the charging of LiPo battery packs use only the licensed chargers with their correspon-
ding connecting leads. Any manipulation of the charger or of the charging lead may cause
serious damages. By means of the charger you have the full and absolutely imperative
control of each single cell of the battery pack.
•
The battery to be charged must be placed on a non-fl ammable, heat resistant and non-
conductive surface. Keep infl ammable and volatile materials well away from the charging
area. Batteries must not be left on charge unsupervised.
•
Avoid short-circuits. Never short-circuit these batteries. Shorting the terminals allows a very
high current to fl ow, and this heats up the cells. This in turn may lead to a loss of electroly-
te, gassing (venting of gas) or even an explosion. When handling Graupner LiPo batteries
keep them well away from conductive objects and surfaces to avoid the danger of a short-
circuit.
•
It is essential to avoid cell voltages above 4.25 V, as higher voltages cause permanent da-
mage to the cells and cause fi re.
•
Take great care never to charge these batteries with reversed polarity. If batteries are char-
ged with reversed polarity abnormal chemical reactions take place, causing cell ruptures,
smoke and fl ames, and the battery gets useless.
•
The permissible range of temperature during the charging and storing of LiPo batteries is
from 0 – 50° C.
•
Storing: LiPo cells should be stored with a charged capacity of 10 – 20 %. If the voltage of
the cells go down under 3 V, it is absolutely imperative to recharge them (10-20 %). Deep-
discharging and storing in a discharged condition (cell voltage under 3 V) render the battery
useless.
•
Batteries must not be placed in a microwave oven or subjected to pressure. This may result
in smoke and fi re or even worse.
•
Never dismantle a LiPo battery. Dismantling a pack may cause internal short-circuits, with
the possible results of gassing, fi re, explosion and other problems.
•
Damaged cells must never be re-used.
•
Indications of damage include broken housings, distortion of battery cells, escaping elec-
