A-1. INTRODUCTION
Please study these instructions, reading them completely and attentively, before using the unit for
the first time. This will guarantee that you will be able to exploit all the facilities of your new
battery charger. The warnings and safety notes are particularly important. Please store these
instructions in a safe place, and be sure to pass them on to the new owner if you ever dispose of
the charger.
In the CHARGER you have acquired a mature product with an excellent performance. It incorporates the
latest semi-conductor technology, controlled by a high-performance RISC micro-processor, to provide
superior charging characteristics combined with simple operation and optimum reliability. These features
can normally be expected only from much more expensive units. The CHARGER represents a reliable
method of charging sintered Nickel-Cadmium (NC, Ni-Cd) packs, Nickel-Metal-Hydride (Ni-MH) batteries,
Lithium-Polymer (Li-Po), Lithium-Manganese (Li-Mn), Lithium-Ion (Li-Io) and LiFePO4(LiFe) batteries,
and also lead-gel and lead-acid (Plumbum: Pb) batteries These sealed, gas-tight batteries have proved
excellent for our purposes in RC models. They are mechanically robust, can be used in any attitude and
are generally highly reliable. They require no special measures for storage apart from protecting the cells
from becoming deep-discharged. The CHARGER can also be used to discharge your batteries and
balance the cells in a pack.
Note
It is important always to observe the charging instructions supplied by the battery manufacturer, and to
keep to the recommended charge currents and times Do not fast-charge batteries unless the
manufacturer states expressly that they are suitable for the high currents which flow during these
processes. When charging new batteries you may also encounter problems with premature charge
termination. Whenever you wish to use a new battery it therefore makes sense to carry out a series of
monitored test charges, so that you can check that the automatic charge termination circuit works
correctly and reliably with your packs, and charges them to full capacity.

A-2. WARNINGS AND SAFETY NOTES
• The software does not take the output current of Output 3 into account when it calculates the charge
power. This means that the charger will re-boot if the internal mains PSU is overloaded. If devices with
a relatively high current drain (more than 1 A) - such as Peltier coolers or heating covers - are
connected to the unit, we therefore recommend that you use only one of the two charge outputs, and
set the power distribution to 50% / 50%, in order to prevent overloading the internal PSU.
In this case the second output can still be used for discharging and balancing a battery.
• This product isn‘t designed for use by children under the age of 14, it isn‘t a toy!
• Protect the charger from dust, damp, rain, heat (e.g. direct sunshine) and vibration. It should only be
operated in dry indoor conditions.
• The case slots serve to cool the charger, and must not be covered or enclosed; set up the charger
with space round it, so that cooling air can circulate unhindered.
• The charger is designed to be powered by a 12 V DC car battery or power supply or 100~240V AC
main socket only. It is not permissible to modify the charger in any way. You must not connect AC
power to the DC input.
• 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. Keep all inflammable and volatile materials well away from the charging area. Provide good
ventilation. Defective batteries can explode or burn!
• Connect the charger 12DC input directly to the car battery using the original cables and connectors
supplied. The car’s engine must be stopped all the time the CHARGER is connected to the car’s
battery. Do not recharge the car battery at any time when the CHARGER 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. 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 unit for charging at any one time.
• The following types of battery must not be connected to the charger:
- Ni-Cd / Ni-MH batteries consisting of more than 18 cells, Lithium-Ion / Li-Mn / Lithium-Polymer /
LiFePO4(LiFe) batteries of more than 7 cells, or lead-acid batteries with a nominal voltage of more
than 12V or 24V.
- Batteries which require a different charge method from Ni-Cd, Ni-MH, Lithium or lead-acid types.
- Faulty or damaged cells or batteries.
- Batteries consisting of parallel-wired cells, or cells of different types.
- Batteries consisting of old and new cells, or cells of different makes.

Page 5/55
- Non-rechargeable batteries (dry cells). Caution: explosion hazard!
- Batteries which are not expressly stated by the manufacturer to be suitable for the currents which
this unit delivers during the charge process.
- Packs which are already fully charged or hot, or only partially discharged.
- Batteries or cells fitted with an integral charge circuit or charge termination circuit.
- Batteries installed in a device, or which are electrically connected to other components.
• To avoid short-circuits between the banana plugs fitted to the charge leads, please always connect
the charge leads to the charger first, and only then to the battery to be charged. Reverse the
sequence when disconnecting.
• As a basic rule always check that the charge quantity is approximately the same as you expected
after the charger has indicated that the pack is fully charged. This is a simple method of detecting a
problem reliably and in good time, should the charge process be terminated prematurely for any
reason. The likelihood of premature termination varies according to many factors, but is at its highest
with deep-discharged packs, low cell counts and particular cell types which are known to cause
problems.
• We recommend that you carry out a series of test charges to satisfy yourself that the automatic
termination circuit is working perfectly. This applies in particular when you are charging packs
consisting of a small number of cells. If the cells feature has a poorly defined voltage peak, the
charger may fail to detect the fully charged state.
• Before charging please check: have you selected the appropriate charge program for the battery?
Have you set the correct charge or discharge current? Have you set the important cut-off voltage
when charging Ni-Cd and Ni-MH packs? Are all connections firm, or is there an intermittent contact
at any point in the circuit? Please bear in mind that it can be dangerous to fast-charge batteries. For
example, if there is a brief interruption due to an intermittent contact, the result is inevitably a
malfunction such as a restart of the charge process, which would result in the pack being massively
overcharged.
• Be careful! A battery could explode or burn, if the charger does have a fault or if the user
does choose the wrong charging program and parameters.
A-3. GENERAL NOTES ON USING THE CHARGER
Charging batteries
When a battery is charged, a particular quantity of electrical energy is fed into it. The charge quantity is
calculated by multiplying charge current by charge time. The maximum permissible charge current
varies according to the battery type, and can be found in the information provided by the battery
manufacturer.
It is only permissible to charge batteries at rates higher than the standard (slow) current if they are
expressly stated to be rapid-charge capable. The STANDARD CHARGE CURRENT is 1/10 (one
tenth) of the cells’ nominal capacity (e.g. for a 1.7 Ah pack the standard charge current is 170 mA).

Page 6/55
• Connect the battery to be charged to the charger output sockets using a suitable charge lead (red =
positive terminal, black = negative terminal).
• Be sure to read the information provided by the battery manufacturer regarding charging methods,
and observe the recommended charge currents and charge times. Do not attempt to fast-charge
batteries unless they are expressly stated to be suitable for the high currents which this charger
delivers.
• Please bear in mind that new batteries do not reach their full capacity until they have undergone
several charge / discharge cycles. You should also be aware that the charger may terminate the
charge process prematurely when connected to new packs, and batteries which have been deep-
discharged.
• A Ni-Cd pack will normally be warm at the end of a rapid-charge process, but if you notice that one
cell of the pack is much hotter than the others, this may well indicate a fault in that cell. Such packs
could fail completely without warning, and should not be used again. Dispose of the battery safely,
preferably taking it to a toxic waste disposal centre.
• Ensure that all connectors and terminal clamps make good, sound contact. For example, if there is a
brief interruption due to an intermittent contact, the result is inevitably a malfunction such as a restart
of the charge process, which would result in the pack being massively overcharged.
• A common cause of malfunctions is the use of unsuitable charge leads. Since the charger is
incapable of detecting the difference between a pack’s internal resistance, cable resistance and
connector transfer resistance, the first requirement if the charger is to work perfectly is that the
charge lead should be of adequate conductor cross-section and should be not be more than
30 cm long Good-quality connectors (gold-contact types) must be fitted to both ends.
• Charging transmitter batteries
A battery installed in a radio control transmitter can usually be recharged via the integral charge
socket which is fitted to the transmitter itself. Transmitter charge sockets generally include a diode
which prevents reverse current flow. This prevents damage to the transmitter electronics should the
charger be connected with reverse polarity, or if a short-circuit occurs between the bare ends of the
charge lead connectors. However, a transmitter battery protected in this way can only be charged by
the CHARGER if the diode is by-passed. Please read your transmitter operating instructions for
information on how to do this. The stated maximum charge current for the transmitter battery must
never be exceeded. To avoid possible damage to the internal transmitter components due to
overheating and heat build-up, we recommend that the battery should be removed from the
transmitter’s battery compartment prior to charging. The transmitter must be set to „OFF“ and left in
that state for the whole period of the charge process.
Never switch a radio control transmitter on when it is still connected to the battery charger. The
slightest interruption in the charge process may allow the charge voltage to rise to the point where it
immediately ruins the transmitter.
Never attempt to carry out any battery discharge or battery maintenance programs via the

Page 7/55
transmitter’s integral charge socket. The charge socket is not suitable for this purpose.
When you set a particular current for charging, the charger only supplies that current if the value does
not exceed the unit’s technical capacity. If you set a charge current which the CHARGER cannot
deliver because it falls outside its technical limits, the unit automatically reduces the current to the
maximum possible value.

power. This means that the charger will re-boot if the internal mains PSU is overloaded. If devices with
a relatively high current drain (more than 1 A) - such as Peltier coolers or heating covers - are
connected to the unit, we therefore recommend that you use only one of the two charge outputs, and
set the power distribution to 50% / 50%, in order to prevent overloading the internal PSU.
In this case the second output can still be used for discharging and balancing a battery.
A-7. CLEANING AND MAINTENANCE
The charger is entirely maintenance-free in use, and requires no servicing of any kind. However, it is in
your own interests to protect the unit from dust, dirt and damp.
To clean the charger, disconnect it from the car battery and any other battery, and wipe it clean with a
dry cloth (don’t use cleaning agents!).
A-8. NOTES AND HANDLING OF RECHARGABLE BATTERIES
• Charging single Ni-Cd or Ni-MH cells, and packs consisting of 1 ... 4 cells, presents the automatic
charge termination circuit with a difficult task. The voltage peak is quite small in such cases, and it
cannot be guaranteed that the cut-off circuit will work reliably. In such conditions the automatic circuit
may not be triggered, or may not terminate the charge at the correct time. For this reason it is
important to carry out a series of monitored test charge processes with your packs in order to
establish whether the charge process is terminated reliably.
• Warm batteries offer much higher performance than cold ones, so don’t be surprised if your batteries
don’t seem so effective in the winter.
• Overcharging and deep-discharging batteries lead to irreparable damage to the cells, and
permanently reduces their maximum performance and effective capacity.
• Never store batteries for a long time in an uncharged, discharged or partially charged state. Charge
your batteries before storing them, and check their state of charge from time to time.
• When purchasing batteries we recommend that you buy good quality products exclusively. Start by
charging new packs at low rates, and work up gradually towards higher currents.
• Batteries should not be charged until shortly before use, as they are then able to deliver their best
performance.
• Do not solder directly to battery cells. The temperatures which occur during soldering can easily
damage the seals and safety valves of the cells. If this should happen, the battery may lose
electrolyte or dry out, and some of its potential performance will be lost.
• Charging any battery at high currents shortens the life expectancy of the pack. Don’t exceed the
maximum values stated by the manufacturer.
• Overcharging inevitably reduces the capacity of the battery, so do not recharge a hot pack, or one
which has already been charged.
• Charging and discharging any battery at a high current shortens the life expectancy of the pack.
Don’t exceed the maximum values stated by the manufacturer.

Page 10/55
• Lead-acid batteries are not capable of being charged at high currents. Never exceed the maximum
charge rate stated by the battery manufacturer.
• Protect batteries from vibration, and do not subject them to mechanical stress or shock.
• Batteries can generate explosive gas (hydrogen) when on charge and when being discharged, so it is
important to provide good ventilation.
• Do not allow batteries to come into contact with water - explosion hazard.
• Never short-circuit battery contacts - explosion hazard.
• Batteries can explode or burn, if they overheat. We suggest to use a LiPo-security hard case
Order-No. 8372 with all Li-battery types and with NiCd und NiMH-batteries for charging.
• Do not open battery cells - corrosion hazard.
• It is best to „balance“, or even up the cells in Ni-Cd and Ni-MH battery packs by first discharging all
the cells separately to 0.9...1.1V and then charging up the pack.
• Please don’t be surprised if your batteries are not as willing to accept charge in winter as in summer.
The ability of a cold cell to accept and store charge is much lower than that of a warm one.
• Battery disposal: exhausted batteries are not ordinary household waste, and you must not dispose of
them in the domestic rubbish. The retail outlet where you purchase your batteries should have a
battery recycling container for proper disposal. Trade outlets are obliged by law to accept exhausted
batteries for disposal.
DELTA PEAK CHARGE TERMINATION for NiCd-/NiMH- Batteries:
CC-CV CHARGING METHOD FOR LiPo/LiIo/LiFe- Batteries
These programs are only suitable for charging and discharging LiFePO4 batteries with a voltage of
3.3 V / Cell, Lithium-Ion batteries with a voltage of 3.6 V / cell, and Lithium-Polymer and Lithium-
Manganese batteries with a voltage of 3.7 V / cell. The outstanding feature of Lithium batteries is their
much higher capacity compared to other battery types. However, this important advantage is offset by
the need to adopt different handling strategies: they must be charged and discharged using specific
methods, otherwise they will be damaged, and can be dangerous. The directions in these instructions
must be observed at all times when handling these batteries. Specific information and safety notes will
also be found in the battery manufacturer’s technical information.
The automatic charge termination circuit (battery full detection)
works on the proven Delta Peak principle (also known as the
Delta-V process), which is already in use in millions of chargers.
The PEAK SENSITIVITY is shown as – delta V in the graph.

The charge process is fundamentally different to that required for Ni-Cd or Ni-MH batteries, and is
termed a constant current / constant voltage method. The charge current required varies according to
the battery capacity, and is set automatically by the charger. Lithium batteries are usually charged at
the 1C rate (1C charge rate = half capacity as charge current. Example: battery capacity 1500 mAh:
1C charge current = 1500 mA = 1.5 A).
Because some types can be charged with up to 2C or 4C charging current, the charging current and
the capacity of the battery must be set separately. When the battery on charge reaches the specific
final voltage which is appropriate to the battery type, the charger automatically reduces the charge
current in order to prevent the battery exceeding the final permissible voltage. If the battery
manufacturer states a charge current lower than the 1C rate, then the capacity (charge current) must
be reduced accordingly.
We recommend the use of the balancer connector, which ensures that your Lithium batteries
are charged optimally, and therefore increases safety and their useful life.
Problems caused by mistreating batteries:
It is very dangerous to overcharge Lithium-Ion batteries, as they tend to react by gassing, overheating
and even exploding. If the final charge voltage of 3.6 V / cell (LiFePO4), 4.1 V / cell (Lithium-Ion) or 4.2
V / cell (Lithium-Polymer and Lithium-Manganese) is exceeded by more than 1%, the lithium ions in
the cell start to change into metallic lithium. This material reacts very violently with the water in the
electrolyte, and this can result in the cell exploding. On the other hand it is also important to avoid
terminating the charge process before the final charge voltage is reached, since this reduces the
effective capacity of the Lithium-Ion cell markedly. Stopping the charge at just 0.1 V under the
threshold means a capacity loss of around 7%. Lithium batteries must not be deep-discharged, as this
leads to a rapid loss of capacity. This effect is irreversible; it is absolutely vital to avoid discharging the
batteries to below 2.5 V / cell.
Caution: the cell type, cell capacity and cell count set on the charger must always be correct
for the battery to be charged; if you make a mistake, the battery could explode and burn! Never
connect a Lithium-based battery to the charger if it features an integral charge circuit! Always
place your Lithium batteries on a non-flammable surface for charging.
The fundamental rule is that Lithium-based batteries may ONLY be
charged using special chargers, and the charge program must be
set up correctly in terms of final charge voltage and capacity for the
battery type in use.

2. CHARGE SETUP MENU FLOW
Warning: To high settings of charging voltage (Li-batteries), charging current (all types)
or delta peak sensitivity (NiMH/NiCd) batteries can cause explosion and fire!
2-1. CHARGE CURRENT
-Set charge currents. Follow the instruction of the battery. Graupner batteries
should be charged with 0.5-1C (f. e. 6N-4200 should be charged with 4.2A).
Transmitter batteries must be charge with less then 2A. Follow the instruction of
the transmitter battery and transmitter.
2-2. PEAK SENS
WARNING! To high settings of the delta peak sensitivity can cause explosion and fire.
-Only for NiCd/NiMH. Follow the instruction of your battery or start with 3mV/Cell.
- If battery is 6cells and 3mV/C is set, the charger should finish as 3mV * 6cell =
18mV.
- In case of NIMH battery, charge can be also finished with Zero-peak.
- Set bigger peak sens values if delta-peak often happens.
- "END:DELTA-PEAK " should be shown if charge is finished with delta-peak.
- "END:ZERO-PEAK should be shown if charge is finished with ZERO-peak.
2-3. PEAK DELAY
- This function is not to detect delta peak which could happen at the initial stage of
charging and which could happen due to the chemical reaction internal battery.
Normal settings are 3-5min.
2-4. TRICKLE
- This current is to compensate battery self discharge after NICD/NiMH fast charging.
- As for Lithium battery, CV ( constant voltage ) is activated instead of trickle charge.
2-5. CUT-TEMP
- Connect the temp sensor to battery pack and when it reaches the selected temp,
charging should stop. Normal settings are 35-50°C.
- This function is likely to be used more to prevent battery pack from being
overheating rather than normal charge completion.
2-6. MAX CAPACITY
- This is to set your wanted charge percentage against the selected battery capacity.
-Set half of the battery capacity ( 50% ) for the purpose of the battery storage. Set
120-125% for fully charging of high current NiCd/NiMH batteries and 100-105% for
charging LiPo-, LiIo-, LiFe- batteries and NiMH RTU (Ready to use) batteries.
- If battery capacity is 3000mAh and if you set 10% out of the total max capacity, the
charger should stop charging at 300mAh.
- If “OFF” is set, this max capacity function is not activated.
- If charging is finished with MAX CAPACITY, “END:CAPACITY should be shown.
