b) Mains Cable/Mains Voltage
• Product setup corresponds to protection class I. Only a proper protective-contact mains socket must be
used for connection of the charger via the mains cable.
• The mains socket to which the plug-in mains unit is connected must be easily accessible.
• Do not pull the mains plug from the mains socket by pulling the cable.
• If the mains unit or charger are damaged, do not touch it. Danger to life from electric shock!
First switch off the mains voltage for the mains socket to which the mains cable is connected (switch
off the corresponding circuit breaker or take out the fuse, then switch off the fault interrupter protection
switch (FI circuit breaker) so that the mains socket is separated from the mains voltage on all poles).
Only then unplug the mains unit from the mains socket.
If the charger is damaged, stop operating it. Take it to a specialised workshop or dispose of it in an
environmentally friendly way.
If the mains cable is damaged, dispose of the damaged mains cable in an environmentally compatible
way. Do not use it anymore. Replace it with a new mains cable of the same specications.
c) Location for Installation
• The charger is intended for dry indoor use only. It must not become damp or wet.
If the charger is operated via the mains cable, there is danger to life from electric shock in case of
moisture/wetness on the charger/mains cable!
• Avoid direct sun irradiation, strong heat or cold. Keep the charger away from dust and dirt. The same
applies to any rechargeable battery that may be connected.
• Choose a solid, at, clean and sufciently large surface for the charger. Never place the charger on a
ammable surface (e.g. carpet, tablecloth). Always use a suitable, non-ammable, heatproof surface.
• Keep the charger away from ammable or easily inammable materials (e.g. curtains).
• Never cover the ventilation slots; danger of overheating and re. Never push any objects into the
ventilation slots of the charger; There is a danger to life from electric shock!

wise, scratches, pressure points or discolourations are possible. The same applies to the rechargeable
battery.
• Do not use the charger inside a vehicle.
• The charger must only be set up, used or stored in places that are not accessible to children. Children
may change the settings or short-circuit the rechargeable battery/battery pack, which can lead to an
explosion. Danger to life!
• Avoid installation in direct proximity of strong magnetic or electromagnetic elds, transmitter aerials or
HF generators. This can affect the control electronics.
• Ensure that the cables are not crushed or damaged by sharp edges. Never place any objects on the
cables.

9
• Do not place any containers lled with liquid, vases or plants, on or next to the charger/mains cable.
When these liquids get into the charger (or the plug connections of the mains cable), the charger will be
destroyed and there is a most severe danger of potentially fatal electric shock or re.
If the charger is operated via the mains cable, rst switch off the mains voltage for the mains socket to
which the mains cable is connected (switch off the corresponding circuit breaker or take out the fuse,
then switch off the fault interrupter protection switch (FI circuit breaker) so that the mains socket is
separated from the mains voltage on all poles). Only then unplug the mains plug of the mains cable
from the mains socket.
If the charger is operated via the DC input (11 - 18 V/DC), disconnect the charger from the voltage/
power supply.
Then disconnect the connected rechargeable battery from the charger. Do not use the charger again -
bring it to a specialist workshop.
d) Operation
• The charger may be operated either via the mains voltage (100 - 240 V/AC, 50/60 Hz) or via a
stabilised direct voltage of 11 - 18 V/DC (e.g. via an external vehicle lead battery or a suitable mains
adapter).
Use only one of the two connection types, but never both at once. This may damage the charger.
• Do not wear any metal or conductive materials, such as jewellery (necklaces, bracelets, rings, etc.)
while you are working with the charger or batteries. A short-circuit at the rechargeable battery or charg-
ing cable poses a danger of burns and explosion.
• Never leave the product unattended while operating. Despite a considerable number of protective cir-
cuits, it is impossible to exclude the possibility of malfunctions or problems during the charging process.
• Ensure that there is sufcient ventilation during operation. Never cover up the charger. Leave enough of
a distance (at least 20 cm) between charger and other objects. Overheating causes a danger of re!
• The charger must only be used to charge (or discharge) rechargeable batteries of types NiMH, NiCd,
LiIon/LiPo/LiFe and lead batteries. Never charge any other rechargeable battery types or non-recharge-
able batteries. There is great danger of re or explosion!
• Always connect the charging cable to the charger rst. Only then must the rechargeable battery be
connected to the charging cable.
When disconnecting, proceed in reverse order - rst disconnect the rechargeable battery from the
charging cable, then the charging cable from the charger.
If the order is chosen incorrectly, there may be a short-circuit of the charger plugs; there is a danger of
re and explosion!
• Only operate the product in moderate climate, never in tropical climate. For more information on ac-
ceptable environmental conditions, see the chapter "Technical Data".
• Never operate the device immediately after it was taken from a cold room to a warm room. The result-
ing condensation may lead to malfunctions or damage!
Let the product reach room temperature before taking it into operation again. This may take several
hours!

10
• Avoid operation in direct proximity of strong magnetic or electromagnetic elds, transmitter aerials or
HF generators. This can affect the control electronics.
• If you have reason to believe that the device can no longer be operated safely, disconnect it immedi-
ately and make sure it is not operated unintentionally.
Disconnect the charger from the voltage/current supply. Do not use the product any more after this, but
take it to a specialised workshop or dispose of it in an environmentally compatible manner.
It can be assumed that operation without danger is no longer possible if the device has any visible dam-
age, the device no longer works, after extended storage under unsuitable conditions or after difcult
transport conditions.
• Keep the entire product at a dry, cool, clean site that is not accessible to children.

6. RECHARGEABLE BATTERY NOTES
Although use of rechargeable batteries in everyday life is a matter of course today, there are many dangers and
problems. In particular, with LiPo/LiIon/LiFe rechargeable batteries with their high energy content (in comparison
with conventional NiCd or NiMH rechargeable batteries), various regulations must be observed in order to avoid the
danger of explosion and re.
For this reason, always ensure that you have read and understood the following information and safety information
when handling rechargeable batteries.
If the manufacturer of the rechargeable battery has provided any other information, read it carefully and
observe it!
a) General Information
• Rechargeable batteries are no toys. Always keep batteries/rechargeable batteries out of the reach of
children.
• Do not leave batteries/rechargeable batteries lying around openly; there is a risk of them being swal-
lowed by children or pets. If swallowed, consult a doctor immediately!
• Rechargeable batteries must not be short-circuited, taken apart or thrown into re. There is a risk of re
and explosion!
• Leaking or damaged batteries/rechargeable batteries can cause chemical burns to skin when touched
without the use of adequate protective gloves.
• Never recharge normal (non-rechargeable) batteries. There is a risk of re and explosion!
Non-rechargeable batteries are meant to be used once only and must be disposed of properly when
empty.
Only charge rechargeable batteries intended for this purpose. Use a suitable battery charger.
• Rechargeable batteries must not get damp or wet.
• Place the charger and battery on a non-ammable, heat-resistant surface (e.g. stone tiles). Main-
tain enough distance from ammable objects. Leave enough distance between the charger and the
rechargeable battery - never place the rechargeable battery on the charger.
• As both the charger and the rechargeable battery heat up during the charge/discharge procedure, it is
necessary to ensure sufcient ventilation. Never cover the charger or the rechargeable battery!
• Never use battery packs made up of different cells.
• Never leave the charging/discharging rechargeable batteries unattended.
• Never recharge a battery directly in the model. Always remove the rechargeable battery from the model
for recharging.
• Always observe correct polarity (plus/+ and minus/-) when connecting the rechargeable battery to
your model or charger. Connecting the battery incorrectly will not only damage the model but also the
rechargeable battery. There is a risk of re and explosion!
This charger has a mechanism that protects against connecting the poles incorrectly. Nonetheless, it is
possible that an incorrectly connected battery may lead to damage in certain situations.

12
• If the product is not to be used for an extended period of time (e.g. storage), disconnect any connected
rechargeable battery from the charger and disconnect the charger from the voltage/current supply.
The charger has no mains switch. If you operate the charger via the mains cable, pull the mains plug
from the socket when you no longer need the charger.
• Do not charge/discharge any battery that is still hot (e.g. caused by high discharging current from the
model). Allow the rechargeable battery to cool down to room temperature before attempting to charge
or discharge it.
• Never damage the exterior cover of a battery. There is a risk of re and explosion!
• Never charge/discharge damaged, leaking or deformed batteries. This can result in a re or explosion!
Dispose of any unusable rechargeable batteries in an environmentally compatible fashion. Do not
continue to use them.
• Remove the rechargeable battery from the charger when it is fully charged.
• Recharge the rechargeable batteries about every 3 months. Otherwise, so-called deep discharge may
result, rendering the rechargeable batteries useless.
• Keep rechargeable batteries in a suitable location. Use a smoke detector in the room. The risk of re
(or the occurrence of toxic smoke) cannot be excluded. Special rechargeable batteries for the model
construction area are subject to great stress (e.g. high charging and discharging currents, vibrations,
etc.).
b) Additional Information on Lithium Batteries
Modern batteries with lithium technology do not only have a clearly higher capacity than NiMH or NiCd
rechargeable battery packs but they also have a considerably lower weight. This makes this type of
rechargeable battery very interesting for application in model construction; so-called LiPo batteries
(lithium-polymer) are often used here.
Rechargeable lithium batteries require special care when charging/discharging, as well as during opera-
tion and handling.
For this reason, we would like to provide you with some information in the sections below about the
dangers and how you can avoid them, thus helping such batteries to maintain their performance for an
extended period of time to come.
Additionally observe chapter 6. a).
• The outer shell of many rechargeable lithium batteries is only made of a thick foil and therefore very
sensitive.
Never destroy or damage the battery, never let the battery fall and do not pierce the battery with any
objects! Avoid any mechanical strain on the battery; never pull the connection cables of the battery!
There is a risk of re and explosion!
These guidelines must also be observed when the battery is inserted into the model or when it is
removed from the model.
• Ensure that the battery does not overheat during usage, recharging, discharging, transport or storage.
Do not place the battery next to sources of heat (e.g. speed controller, motor), keep the battery away
from direct sunlight. There is a risk of re and explosion if the battery overheats!

13
The battery must never heat up to more than +60 °C (observe any additional information from the
manufacturer!).
• If the battery is damaged (e.g. after the crash of an aircraft or helicopter model) or the exterior cover
is soaked/has expanded, do not use the battery. Do not charge it anymore. There is a risk of re and
explosion!
Handle the battery with care, use suitable protective gloves. Dispose of the rechargeable battery
environmentally compatibly.
Never keep such rechargeable batteries in an apartment or a house/garage anymore. Damaged or
bloated lithium rechargeable batteries may catch re suddenly.
• Only use a suitable charger to charge lithium batteries or use the correct charging procedure. Due to a
risk of re and explosion, conventional chargers for NiCd, NiMH and lead batteries must not be used!
Always choose the right charging procedure depending on rechargeable battery.
• When charging a lithium battery with more than one cell, always use a so-called balancer (one is
already integrated into the supplied charger).
• Charge LiPo batteries with a max. charging current of 1C (if not indicated otherwise by the battery
manufacturer!). This means that the charging current may not exceed the capacity value imprinted on
the battery (e.g. battery capacity 1000 mAh, max. charging current 1000 mA = 1 A).
With LiFe and LiIon batteries, you must observe the instructions of the battery manufacturer.
• The discharging current must not exceed the value printed on the battery.
For example, if a value of "20C" is printed on a LiPo battery, the max. discharging current is 20 times
the battery's capacity (e.g. battery capacity 1000 mAh, max. discharging current 20C = 20 x 1000 mA =
20 A).
Otherwise, the battery will overheat, causing deformation/bloating of the battery or explosion and re!
The printed value (e.g "20C") does not generally refer to the constant current, but to the maximum cur-
rent that the battery is capable of producing in the short-term. The constant current therefore should not
be higher than one half of the given value.
• Observe that the individual cells of a lithium rechargeable battery must not be deep-discharged. A deep
discharge of a lithium rechargeable battery will lead to permanent damage/destruction of the recharge-
able battery.
If the model does not provide protection against total discharge or possess a visual display indicating a
low battery, remember to switch off the model in time.

Also observe the correct voltage setting for multi-cell battery packs. For example, the individual cells in a
two-cell battery pack may be switched in parallel or in series.
If the maximum permissible charging current for the rechargeable battery is exceeded or a wrong cell
number/voltage setting is chosen, there is a danger of destroying the rechargeable battery. There also is
a danger of re and explosion from the rechargeable battery!
Further notes on the max. charging current and the cell number/voltage can be taken from the data
sheets or the labels of the rechargeable batteries; these data take precedence over the information in the
above table.
Important!

9. COMMISSIONING
a) Connection to a Voltage/Current Supply
Attention!
Always connect the charger to the voltage/current supply rst; only then must a rechargeable battery be
connected to the charger.
The charger offers two different options for operation:
• Operation via the mains voltage (100 - 240 V/AC, 50/60 Hz)
• Operation via stabilised direct voltage (11 - 18 V/DC, e.g. via an external vehicle lead battery or a mains adapter)
Never use both operating modes at the same time. This may damage the charger. Loss of guarantee/
warranty!
The charger has a maximum charging output of 50 W. If the charger is to be operated via the direct voltage input,
the power supply strength must be chosen depending on how high the actually used charging output is (depending
on the rechargeable battery type, cell number and the charging current set).
When fully using the maximum charging power of 50 W, the conversion loss leads to an approx. 20% - 30%
higher power intake.
If the charger is not to be operated at a 12 V vehicle lead battery, but via a xed voltage mains unit, it must be
able to supply a correspondingly high current (we suggest at least 6,5 A).
When using the direct current input, observe the correct polarity when connecting (plus/+ and minus/-).
The charger will switch on automatically after connecting to the voltage/
current supply. The display will light up; the start message will appear (see
picture on the right) and the charger will emit a brief signal sound.
The charger then is in its main menu.

b) Connection of a Rechargeable Battery to the Charger
Please observe the following points before connecting or charging/recharging the battery:
• If you have not done so already, please read chapters 5, 6 and 7 completely and ensure that you have
understood the information there.
• Do you know all of the information you need to know about your rechargeable battery? Unknown or
unlabelled batteries, the necessary values of which you do not know, must not be connected/charged/
discharged!
• Have you selected the correct charging/discharging program for the type of battery you are using?
Incorrect settings will damage the charger and the battery; there is a danger of re and explosion!
• Did you set the correct charging or discharging current?
• Have you selected the correct voltage (e.g. for multiple-cell LiPo batteries)? A two-cell LiPo battery may
be switched in parallel (3.7 V) or series (7.4 V).
• Are all connector cables and plugs undamaged, do the plugs stay rmly in the sockets? Worn plugs
and damaged cables should be replaced.
• Connect only one rechargeable battery or a single battery pack to the charger output, but never several
at once.
• When connecting a rechargeable battery to the charger, always connect the charging cable to the
charger rst. Only then must the charging cable be connected to the rechargeable battery. When dis-
connecting, proceed in reverse order (rst disconnect the rechargeable battery from the charging cable,
then the charging cable from the charger).
Failure to do so presents the danger of a short circuit. This can result in a re or explosion of the
rechargeable batteries!
• If you wish to charge battery packs that you have manufactured yourself, the cells must be identical in
their construction (same type, same capacity, same manufacturer).
The cells must also be charged to the same level (lithium batteries can be balanced out using the
balancer. This is, however, not possible with other battery packs such as NiMH or NiCd).
• Before connecting a rechargeable battery/battery pack to the charger, disconnect it completely, e.g.
from a ight or speed controller.
Important when charging/discharging a lithium battery pack with balancer connection:
Multi-cell lithium battery packs usually always have a balancer connection. This permits the charger to monitor the
voltage of every single cell separately at all times.
The charger adjusts the voltage of all cells to each other if there are deviations. The balancer prevents that one or
several cells are over-charged or other cells not sufciently fully charged by this. The balancer therefore protects
both from over-charging (which may cause re or explosion) and from deep discharge of a single cell, and thus
ensures best performance of the battery pack in your model.

18
Procedure when connecting a battery pack to the charger:
1. First connect the charging cable to the two 4 mm round sockets of the charging output. Ensure correct polarity
(red cable = plus/+, black cable = minus/-).
The charging cable must not be connected to the rechargeable battery yet! There may be a short-circuit
of the charger plugs; there is a danger of re and explosion!
2. Connect the charging cable to the rechargeable battery now. Ensure correct polarity (red cable = plus/+, black
cable = minus/-).
3. If the lithium rechargeable battery has a balancer cable, connect it to the corresponding connection of the
charger (for 2 to 6-cell rechargeable batteries). Always observe the proper shape of the socket and plug on the
charger and the rechargeable battery. Do not use any force for plugging in!
The charger has XH-sockets. If the connection plug of the rechargeable battery has a different plug build, you
need to use the corresponding adapters (not enclosed, available as accessories).
Proceed in the following steps when disconnecting a rechargeable battery:
1. If you have connected a lithium rechargeable battery with a balancer cable to the charger, disconnect it from the
charger.
2. Then disconnect the charging cable from the rechargeable battery.

Always proceed in this order!
The rechargeable battery must always be disconnected from the charging cable (and from the balancer
connection for lithium rechargeable batteries) rst. Only then must the charging cable be disconnected
from the charger.
Any other order poses danger of short circuit by the two round plugs of the charging cable connected to
the rechargeable battery, as well as danger of re and explosion!
