User manual

• Make sure to observe the charging and discharging
instructions.
Storage
Lithium lithium-ion/lithium polymer cells should
be stored charged with 10-20% of their
capacity. If the cell voltage falls below 3 V, the
lithium-ion/lithium polymer cells must be recharged to
10-20% of the full capacity. Otherwise, the battery will
die during storage and become useless.
Special instructions on discharging Graupner
lithium-ion/lithium polymer batteries
•
A continuous current of approximately 1 C
does not pose a problem for Graupner
lithium-ion/lithium polymer batteries. If the
current is higher, refer to the instructions in the
catalogue. Bear in mind the maximum load for the
plug-in system (see the maximum discharge current
on battery).
• Discharging below 2.5 V per cell will damage the
cells and should therefore be avoided at all costs.
• The batteries should never be short-circuited. Short-
circuits generate a very high current which heats
up the cells. This causes a loss of electrolyte, gas
formation or even explosions. Graupner lithium-ion/
lithium polymer batteries should therefore be kept
away from and not touch conductive surfaces due to
the short-circuit hazard.
• The battery's temperature during discharging should
never exceed +70°C. Otherwise, make sure that the
battery is sufficiently cooled, or reduce the discharge
current. The temperature can be easily checked
using the infrared thermometer (order No. 1963).
However, the battery may not be discharged using
the transmitter's charging socket. This socket is not
designed for this purpose.
Additional instructions on handling
•
The battery capacity decreases each time
it is charged and discharged. Charging
when the temperature is too high or too
low can also gradually reduce the battery's capacity.
After 50 cycles, the battery capacity of models is
only 50-80% of that of a new battery due to the
occasionally high discharge current and induction
current of the motor, even when all charging and
discharging instructions have been followed.
• Batteries may only be series-connected or parallel-
connected in exceptions since the cell capacity and
charge can differ. The battery packs that we supply
are therefore preferable.
• The connectors of lithium-ion/lithium polymer
batteries are not as robust as other batteries. This
holds true particularly for the plus connector. The
connectors can easily break.
Cell connector
Direct soldering on the battery cells is not
permitted.
The heat from direct soldering can damage
battery components such as the separator or isolator.
Battery connectors should only be created by spot
welding in the factory. If the cable is missing or severed,
have it repaired professionally by the manufacturer or
dealer.
Replacing individual battery cells
Individually battery cells may only be
exchanged by the manufacturer or dealer and
not by the user.
Do not use damaged cells
Damaged cells may not be used.
Indications of damaged cells include damaged
housing packaging, deformed cells, the smell
of electrolyte or leaking electrolyte. The battery may not
be used in these cases.
Damaged or useless cells are considered hazardous
waste and must be disposed of properly.
General warnings
Batteries may not be immersed in liquid such
as tap water, sea water or beverages. Avoid all
contact with liquids of any kind.
Instructions on the mz-24 HoTT remote control set
Order No. S1006
The remote control set comes standard with a
lithium-ion transmitter battery with an
integrated protective circuit (subject to
modification). A warning appears in the transmitter
display after the voltage falls below the default low-
voltage limit of 3.60 V which may be modified by the
user.
