Intended use
In the QUICK LiPo 15, you have acquired a sophisticated product with excellent features. Its state-ofthe-art semi-conductor technology controlled by a powerful microprocessor provides excellent charging
properties, means that the charger is easy to use and ensures optimum reliability. The QUICK LiPo 15
can be used to charge virtually all lithium polymer batteries used in model-building. Connect the charger's
100 ~ 240 VAC input to a mains wall socket or the charger's DC input to a car battery or power supply unit
with a capacity of at least 10 A with 11 to 15 VDC.
Always follow the charging instructions of the battery manufacturers and adhere to the charging current
and charging times. The quick-charge process may only be used by batteries that have explicitly been
described as suitable for the high charging current that this involves. Please be aware that new batteries
may only reach their full capacity after several charging/discharging cycles. Charging may also be
terminated prematurely when new batteries are used. You must carry out a series of test charges to
check that the automatic termination function is working correctly and reliably and that the battery is being
charged to the correct capacity.

The requirements placed on rechargeable batteries vary depending on how they are used. This in turn means
that various types of connectors are required. Please note that connections, names and polarities may vary
from one manufacturer to another. You must therefore only ever use compatible original connectors of the
same type.
You must also only use original charging cables with a sufficient wire cross-section.

Disposal instructions
This symbol calls attention to the following notices regarding how individual materials
and products must be disposed of by the user.
Warning and safety notices
Protect the charger against dust, moisture, rain, heat (e.g. direct sunlight) and vibrations.
Only use in dry locations.
The slots in the housing are used to cool the device and must not be covered or sealed.
The device must be positioned so that the air can circulate without restriction.
Do not connect several chargers to one power strip – danger of overloading the socket –
fire hazard!
The charger is suitable for connection to a 12 V car battery or power supply unit
(11 to 15 VDC). Never connect an AC voltage to the DC voltage input. Fire hazard!
No modifications whatsoever may be made to the charger.
The charger and the battery to be charged must be placed on a non-combustible, heatresistant and non-conducting surface during operation. Never place the device on a car seat,
carpets or similar surfaces. Combustible or highly flammable objects are to be kept away
from the charging area. Ensure good ventilation.
Batteries can explode or catch fire if they are defective.
Connect the charger directly to the car battery using the original connection cables and
terminals only. The vehicle's engine must be turned off while the charger is connected to
the vehicle. The car battery must not be being charged by another charger at the same time.
The charge outputs and the connection cables must not be modified or connected to each
other in any way. There is a danger of short circuit between the charge outputs and the vehicle
body when the charger is operated from the car battery. The charging cables and connection
cables must not become coiled during operation. Prevent short circuits between the charge
output or battery and the vehicle body. For this reason, never place the device directly on
the vehicle body.
Never leave the charger unattended when it is connected to the power supply.
Only operate your charger in rooms fitted with a smoke detector.
Only one battery must be connected to the charger at once.
The following batteries must not be connected to the charger:
• NiCd/NiMH batteries, LiFePO4/lithium-ion/lithium polymer batteries with more than 3 cells,
lead-acid batteries.
• Batteries that require different charging technology to LiPo batteries.
• Defective or damaged cells or batteries.
• Batteries from different cells or cells connected in parallel.
• Combinations of old and new cells or cells from different manufacturers.
• Non-rechargeable batteries (dry cell batteries). WARNING: Explosion hazard!
• Batteries or cells that have not been explicitly approved by the manufacturer for the
charging currents that occur when charging a battery with this charger.
• Cells or batteries that have already been charged, are hot or are not fully discharged.
• Batteries or cells with an integrated charging or termination circuit.
• Batteries or cells that are installed in a device or are electrically connected to other
components at the same time.
To prevent short circuits at the banana connectors of the charging cable, please always
connect the charging cable first to the charger and then to the battery. Complete the sequence
in reverse to disconnect the cable.
As a basic rule, always check that the charge level is approximately as expected after the
charger has indicated that the battery is fully charged. This is a simple method of detecting a
problem reliably and in good time should the charging process be terminated incorrectly for
any reason. The likelihood of premature termination is subject to various factors but is at its
highest with deep-discharged batteries, small numbers of cells and particular types of battery.
Carry out a series of test charges (especially with small numbers of cells) to check that the
automatic termination function is working correctly. If the voltage peak is too weak, the charger
may fail to detect that the battery is fully charged. Fire and explosion hazard!
Do not connect several chargers to one power strip – danger of overloading the socket –
fire hazard!
Are all the connections functioning properly? Are there any loose connections? Please
be aware that charging batteries using the quick-charge process can be dangerous. An
interruption caused by a loose connection, no matter how brief, will inevitably lead to
malfunctions, may cause the charging process to restart and may drastically overcharge
the connected battery. Fire and explosion hazard!
Charging the transmitter: even a brief interruption to the charging process can cause the
charging voltage in the charger to rise to an overvoltage that will lead to the immediate
destruction of the transmitter. Fire hazard!
Information on handling batteries
Always carry out a series of monitored test charges on new batteries to check whether
the termination function is working correctly for the batteries you are using.
Fire and explosion hazard!
Overcharging and deep-discharge processes cause irreparable damage to the cells,
permanently impair the performance of the battery and reduce its capacity.
Never store batteries for extended periods when they are uncharged, empty or partially charged.
Charge the batteries to their specified storage capacity before placing them in storage and check
their charge level from time to time.
When buying batteries, make sure they are of good quality. Start by charging new batteries
at low rates, and work up gradually towards higher currents.
Only charge batteries shortly before use, as they are then able to deliver their best
Do not solder directly onto the batteries – the temperatures which occur during soldering
can damage the seals and safety valves of the cells. This would cause the battery to lose
electrolyte or dry out, and some of its performance would be lost.
Overcharging damages battery capacity. Therefore, do not charge the battery if it is hot
or has already been charged.
Charging and discharging any battery at a high current shortens its life expectancy.
Do not exceed the values specified by the manufacturer.
Protect batteries from vibration and do not subject them to mechanical stress.
Batteries can generate explosive gas (hydrogen) when charging and during operation.
It is therefore important to provide adequate ventilation.
Do not allow batteries to come into contact with water – explosion hazard!
Never short-circuit battery contacts – explosion hazard!
Batteries can explode or catch fire if they are defective. We therefore recommend charging
the batteries in a LiPo safety case (order no. 8370 or 8371).
Do not open batteries – risk of chemical burns.
Do not be surprised if your battery packs do not charge as quickly and their level of
performance is not as high 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.
Information on the German Batteries Act: exhausted batteries are regarded as hazardous
waste and must not be disposed of as domestic waste. The specialist retailer where you
bought your batteries will have battery recycling containers which you can use to dispose
of them. The retailer is obliged by law to accept exhausted batteries for disposal.
Charging batteries
When a battery is charged, a specific amount of electrical energy is supplied to the battery.
This amount is calculated by multiplying the charging current by the charging time. The
maximum permissible charging current depends on the battery type and can be found in the
information provided by the battery manufacturer.
The standard charging current may only be exceeded if the battery information explicitly
states that the battery is suitable for quick-charge processes. The STANDARD CHARGING
CURRENT is 1/10 of the cells’ nominal capacity (e.g. for a 1.7 Ah battery, the standard charging
current is 170 mA).
General operating notices
The battery to be charged is connected to the charger's connection sockets (red = positive
pole, black = negative pole). Only use original charging cables with a sufficient wire crosssection.
Always follow the charging instructions of the battery manufacturers and adhere to the charging
current and charging times. The quick-charge process may only be used by batteries that have
explicitly been described as suitable for the high charging current applied by the charger.
Please be aware that new batteries only reach their full capacity after several charging/
discharging cycles. Charging may also be terminated prematurely, particularly when new or
deep-discharged batteries are used.
If a cell in a LiXX battery pack has become particularly hot following a quick-charge process,
this may indicate a fault in that cell. You must not continue to use this battery pack (exhausted
batteries must not be disposed of as domestic waste).
A common cause of malfunctions is the use of unsuitable charging cables. As the charger
cannot distinguish between the battery's internal resistance, cable resistance and connector
resistance, the first requirement for ensuring that the charger functions correctly is to use a
charging cable with a sufficient wire cross-section, that is no more than 30 cm in length and
has high-quality connectors on both sides (gold contacts).
A battery installed in a remote-control transmitter can be charged via the charging socket,
which is generally fitted on the transmitter.
Transmitter charging sockets usually contain a diode that prevent reverse current. This
prevents damage to the transmitter due to reverse polarity or if a short circuit occurs between
the bare ends of the charging cable connectors.
The maximum charging current permitted for the transmitter must never be exceeded.
To prevent damage to the internal transmitter components due to overheating and heat buildup, the transmitter battery should be taken out of the transmitter battery compartment.
The transmitter must be switched to "OFF" during the entire charging process.
Never switch on a remote-control transmitter while it is connected to the charger.
Do not discharge the battery or carry out battery maintenance programmes via the charging
socket. The charging socket is not suitable for this purpose.
The charger only supplies the required charging current if the current is within the technical
limits of the charger. If the charger is set to receive a charging current that is outside its
technical limits, the value is automatically reduced to the maximum possible value. In this
case, the display shows the charging current which is actually supplied.
Care and maintenance
Care instruction!
The charger is entirely maintenance-free and therefore requires no servicing of any kind.
However, it is in your own interests to protect the charger from dust, dirt and moisture.
Care instruction!
To clean the charger, disconnect it from the car battery and battery pack and gently wipe
it clean with a dry cloth only (do not use any cleaning agents).

Using the charger for the first time
Connect the charger's 100 ~ 240 VAC input to a mains wall socket or the charger's DC input to a car
battery or power supply unit with a capacity of at least 10 A with 11 to 15 VDC.
WARNING: Never connect the two inputs at the same time. The power must only
ever be supplied by one input.
The charger beeps twice and the status LED flashes green approx. every four seconds.
The QUICK LiPo 15 is ready for operation. Connect the battery to start the charging process.
The slide switch can be used to alter the charging current.
Charging process for LiPo batteries
Starting the charging process:
Use the slide switch to select the required charging current and connect the battery to the balancer
connection and charger connection cable or Tx/Rx socket. The charger will beep briefly and the
charging process will then start.
Note: 1 or 2S LiPo batteries will still be charged if the balancer cable is not connected to the charger.
Nevertheless, we strongly recommend that you always use the balancer cable. If you have a 3S LiPo
battery, however, the balancer cable must be connected, as otherwise the charging process will not
The status LED flashes to indicate the number of cells that are connected, e.g. it will flash twice if
you have a 2S LiPo battery.
WARNING: If the number of flashes does not match the number of cells in the battery
you have connected, stop the charging process immediately by disconnecting
the battery – fire hazard!
Never connect 2 batteries at the same time. Only one charging output (either the
charger connection cable or the JR socket) may be used at once.
Notice: If the charger is connected to a mains wall socket, the maximum charging current is limited
to 2.5 A even if the slide switch is set to 4 A.
The charging current can also be altered during the charging process using the slide switch.
Please observe the following when charging a 3S LiPo battery at 12 VDC:
Due to the slight difference between the charger's input voltage (generally approx. 12 to 13 V) and
the charge termination voltage of a 3S battery (12.6 V), it is not possible to fully charge the battery
– subtract a loss in voltage of approx. 0.5 V from the actual input voltage to calculate the maximum
charging voltage.
In general, however, the special LiPo charging process (CC-CV) allows capacities of approx. 85 to
95% to be achieved with a charge termination voltage of 12.3 to 12.5 V, meaning that you will be
able to operate your model without any problems.
Stopping the charging process:
Once the battery is fully charged, the charger will beep for approx. 10 seconds, the LED will then
change to red and the battery will continue to be supplied with trickle current.
If the battery is not to be supplied with trickle current, it must be disconnected from the charger as
soon as charging is complete.
The safety timer always stops the charging process after 90 minutes.
Error messages and warnings
The charger is equipped with a wide range of protective and monitoring systems designed to check
the individual functions and device electronics. If any of the charger's limit values are exceeded, this
will cause the LED displays described below to be shown or the charging process to be stopped (e.g.
if the car battery is almost flat) and a continuous warning tone to be displayed.
