Using The Charger For The First Time - GRAUPNER LIPO-QUICK-CHARGER 4 Operating Manual

Using the charger for the first time

Using the charger for the first time
Connect your LiPo-Quick-Charger 4 to a 12 V
power source of adequate capacity.
Check polarity carefully!
The ideal power source is a 12 V car battery or
other suitable lead-acid battery (Order No. 2593:
12 V / 24 Ah).
Alternatively a stabilised mains PSU with a rated
output of 12 - 14 V and at least 5 A can be used,
e.g. Order No. 6445 (13.8 V / 7 A) or Order No.
94450 (13.8 V / 5-7 A).
Stand-by mode
When you connect the LiPo-Quick-Charger 4 to
the power source, the blue LED starts flashing
at three-second intervals.
Caution: if you press the START/STOP button
while the charger is in charge mode, battery
charged mode or error mode, the Li-Po Charger
4 reverts to Stand-by mode.
Charge mode
Now connect a suitable genuine GRAUPNER
Lithium-Polymer battery pack to the output
of the LiPo-Quick-Charger 4. The pack must
consist of no more than four cells.
Set the potentiometer following to the desired
capacity from 100 to 5000mAh. The charger is
able to generate the optimal charge current for
your Li-Po battery pack.

If you are charging a Lithium-Polymer pack
consisting of one to three cells, press the
START/STOP button briefly after connecting
the battery to the charger. You will hear a loud
audible signal to confirm that the button was
pressed, and the blue LED (for 1 - 3 cells)
lights up; it continues to glow during the charge
process. If you are charging a Lithium-Polymer
pack consisting of four cells, hold the START/
STOP button pressed in for about two seconds
after connecting the battery to the charger.
You will hear two short audible signals to con-
firm this. The red LED (for 4 cells) lights up; it
continues to glow during the charge process.
You can interrupt the charge process at any
time by pressing the START/STOP button. The
LiPo-Quick-Charger 4 then reverts immediately
to Stand-by mode. The LiPo-Quick-Charger 4
has been developed to provide as simple and
safe a means of charging sensitive Lithium-Po-
lymer cells as possible. During the entire charge
process the special Lithium charge program
calculates the optimum current for each phase
of charging, with a maximum current of 3 Amps.
The effect of this is that the LiPo-Quick-Charger
4 starts with a relatively low charge current,
then analyses the battery completely before
increasing the charge current fully automati-
cally. When the pack is approaching maximum
capacity, the charger reduces the charge current
again, also completely automatically.
