General Safety Notes
Introduction
Please be sure to read right through these ope-
rating instructions attentively before you attempt
to use your new charger, as this will ensure that
you can make full use of all of its facilities. Take
particular note of the warnings and safety notes.
These instructions should be kept in a safe
place; if you ever dispose of the charger be sure
to pass them on to the new owner.
The Li-Po Charger 4 is a sophisticated product
offering superb facilities and features. The
use of the latest semi-conductor technology,
controlled by a high-performance RISC micro-
processor, provides outstanding charging per-
formance, simplicity of operation and optimum
reliability - features which are usually only to be
found in much more expensive units.
The Li-Po Charger 4 is capable of charging
batteries consisting of up to four Lithium-Poly-
mer cells.
If the battery consists of one to three cells, the
unit automatically detects the cell count and
calculates the required charge parameters
automatically.
If you wish to charge four Lithium-Polymer cells,
you must set the cell count manually, as fully
automatic operation is only possible with up to
three cells.
Note
Always read and observe the charging instruc-
tions supplied by the battery manufacturer, and
keep to the charge currents and charge times
stated in them. It is not safe to fast-charge Lithi-
um batteries unless they are expressly stated to
be suitable for high charge currents.
Lithium-Polymer cells are very sensitive.
For this reason they should only ever be
charged in conditions when the entire charging
process can be supervised constantly.
Warnings and safety notes
• Protect the charger from dust, damp, rain,
heat (e.g. direct sunshine) and vibration. It
should only be operated in dry indoor conditi
ons. Provide good ventilation.
• The case slots serve to cool the charger, and
must not be covered or enclosed; set up the
charger with space all around it, so that
cooling air can circulate unhindered.
• The charger is designed to be powered by
a 12 V car battery or a mains PSU recom
mended by Graupner. Do not make any
modifications of any kind to the unit.
• The charger and the battery to be charged
should be set up on a heat-resistant, non-
inflammable and non-conductive surface
before use. Never place the charger directly
on a car seat, carpet or similar surface. Keep
all inflammable and volatile materials well
away from the charging area. Provide good
ventilation.
• Connect the charger directly to the car battery
using the original cables and connectors
supplied. The car’s engine must be stopped
all the time the Li-Po Charger 4 is connected
to it.
• The charge output sockets and connecting
leads must not be modified, and must not
be inter-connected in any way. There is a
danger of short-circuit between the charge
outputs and the vehicle’s bodywork when the
charger is connected to the car battery. The
charge leads and connecting leads must not
be coiled up when the charger is in use. Avoid
short-circuiting the charge output or the model
battery with the car bodywork, even though
the Li-Po Charger 4 is protected against such
errors. For this reason the charger must never
be placed directly on the vehicle’s bodywork.
• Never leave the charger running or connected
to the car battery unsupervised.
• Only one battery may be connected to the
charger for charging at any one time.
• The charger is only suitable for charging
Lithium-Polymer batteries consisting of up to
four cells.
• To avoid short-circuits between the banana
plugs fitted to the charge lead, please always
connect the charge lead to the charger first,
and only then to the battery to be charged.
