6.1. Charging batteries
When carrying out the following procedures
be sure to observe the Safety Notes and the
General Charging Notes.
• Connect the MULTIcharger LN-3008 EQU
to your car battery using the crocodile clips
provided. Alternatively connect the unit to a
stabilised mains PSU using the 4 mm
banana plugs. The output voltage of the
PSU must be between 11 V and 15 V.
Maintain correct polarity: red = positive
terminal, black = negative terminal. The
charger is now in stand-by mode, and the
POWER LED glows.
• Connect the charge leads to the charger (
NiXX/LiXX Charge), and then connect the
battery to the charge lead. Maintain correct
polarity: red = positive terminal, black =
negative terminal.
• If you wish to charge a Lithium battery (LiPo,
LiIo or LiFe) consisting of 2S or 3S cells, you
should also connect its balancer plug to the
EQUALIZER Port of the MULTIcharger LN-
3008. Remember to maintain correct
polarity. Suitable adaptor sets for connecting
Lithium batteries with Graupner / robbe or
Polyquest balancer plugs are listed in
Chapter 8. – Accessories.
• How the integral EQUALIZER works: this
function is used to compensate for voltage
variations in the individual cells of your LiXX
battery while it is being charged by the
MULTIcharger LN-3008 EQU. This ensures
that all the cells of your battery will be at the

same voltage when the charge process is
complete.
• Example: charging a 3S LiPo battery
without using the integral EQUALIZER:
Towards the end of the charge process the
individual cell voltages are 4.0 V, 4.2 V and
4.4 V. This equates to a total voltage of 12.6
V, and the charger would terminate the
charge process at this point.
In this example the 4.4 V cell would already
be overcharged and damaged, whereas the
4.0 V cell would not yet be fully charged.
If you use the integral EQUALIZER of the
MULTIcharger LN-3008 EQU, the unit
compensates for the voltage differences
during the charge process, ensuring that all
three cells reach the final charge voltage of
4.2 V at the same time, and are therefore
perfectly charged.
• Press the BATT TYPE button to change the
battery type; the currently set type is
indicated by the appropriate LED.
• The MULTIcharger LN-3008 EQU is
capable of charging the following battery
types:
- Lithium-Polymer (LiPo)
- Lithium-Ionen (LiIo)
- Lithium-Ferrit (LiFe)
- Nickel-Metal-Hydride (NiMH)
- Nickel-Cadmium (NiCd) batteries
• The rotary knob marked CHARGE
CURRENT is used to select the appropriate
charge current for your battery. Caution:
take care not to alter the charge current
accidentally while the battery is on
charge!
• Always
charge
batteries at the 1C rate (C = capacity /
hour). This means: if your battery has a
capacity of 2100 mAh, charge it at 2.1 A.
LiFe batteries should be charged at a rate
no higher than the charge current stated
by the manufacturer.
The charger charges the pack using the
constant current / constant voltage method,
but in any case terminates the charge
process after a maximum of three hours
(Safety Timer).
• NiMH and NiCd batteries should also be
charged at the 1C rate. However, the
MULTIcharger LN-3008 EQU should only
be used to charge NiMH and NiCd
batteries which are expressly marked as
fast charge capable. The charger
