SET Battery Type: The QUADRA-PRO 2 can charge 4 different cell types and incorporates the designated charge
algorithms for each particular cell type for best performance, reliability and safety.
NiMH/NiCd charging with constant current + delta-peak detection. This is the most popular charging method for
NiMH/NiCd-batteries in competition.
LiPo/LiFePo charging using the CC/CV-charging method. With this charging method, the battery gets charged with
a constant current first. As soon as the battery voltage reaches the max. charging voltage of the LiPo- (4.2V/
cell) or LiFePo- (3.7V/cell) battery, the charger automatically reduces the charging current till the battery is
fully charged.
Caution: Always choose the correct BATTERY TYPE setting for the battery you want to charge, as wrong setting may result
in damage to the battery, fire or explosion!
SET Charge Current: The charge current can be set from 0.1 to 5.0A. If not otherwise specified by the battery manuf-
acturer, choose 0.5C charge rate which is always a safe value!
SET Charge Delta Peak: With NiMH/NiCd-batteries, you only obtain the optimum battery performance by slightly
„overcharging“ the battery. In real terms, it will not be overcharged, but charged to an optimum level. The battery voltage
drops at the end of the charging process (delta). The size of the drop (delta peak) is adjustable in the range between 5 - 200mV.
The higher the value, the hotter the battery will be at the end of the charge. We recommend to start with the works-default
settings.
Note: The adjustable Delta-Peak value applies to the whole battery pack and not to one single cell!
SET Charge Trickle: This current, which flows after delta peak cutoff, is adjustable from 0.0A to 0.25A to achieve the
highest possible voltage for NiCd cells. Set this function to „Off“ for NiMH cells.

CHARGE
SET Charge LiPo/LiFePo Volt (pack voltage): The packs rated vol-
tage for LiPo- and LiFePo-batteries must be set according to the packs number of
cells. See right table.
* C=Nominal capacity of the battery. E.g. with a nominal capacity of 3300mAh (3.3Ah),
the battery can be charged with a max. current of 3.3A:
DISCHARGE
The adjustable discharge circuit (0.1 to 1.0A) can be used for 1-14 cell NiMH/NiCd-packs and 1-5 cell LiPo/LiFePo-packs.
The QUADRA-PRO 2 informs you about all the data relating to the battery pack, e.g. discharge time, capacity and average
voltage.
By discharging your battery pack on the QUADRA-PRO 2 after use, you obtain vital information about remaining capacity for
optimizing your motor or gear ratio for the next run. This also maintains your battery packs in good condition.
SET Discharge Current: The discharge current can be set from 0.1 - 1.0A.
SET Discharge Voltage: The cut-off voltage can be adjusted from 0.9 - 14.0V depending on the number of cells. We
recommend a cut-off voltage of 0.9V/cell with NiMH/NiCd-, 3.0V/cell with LiPo-and 2.6V/cell with LiFePo-batteries.
This means for example: - 5.4V for 6-cell NiMH/NiCd - 6.0V for a 2-cell LiPo - 5.2V. for a 2-cell LiFePo
This fully automatic cycling/matching function allows you to determine the actual performance of your packs before using
them. Battery packs change during their life span. Use the QUADRA-PRO 2 to detect the actual quality of your packs. This
prevents nasty surprises.
The “Cycle” mode uses the charge and discharge values of the currently selected programm, stored under “Settings”. The
pack is first discharged, then charged and finally discharged. At the end of the process, the pack capacity and the average
discharge voltage are displayed.
There is a short delay in the timer during cycle operation, in order not to overheat the batteries, which is as following:
- Initial Discharge -> Charge: 1min (if discharge was finished within 10min), otherwise 5min
- Charge -> Discharge: 1min (if charge was finished within 10min), otherwise 5min
Note: The „Cycle“ function can of course be used for all types of cells (NiMH-NiCd-LiPo-LiFePo).

Partial Charge Mode: Never store your batteries completely empty as this will harm them and lower their performance. Due to this fact,
the QUADRA-PRO 2 features a „Partial charge“ mode. With this function, you can set a fixed capacity value and the battery will be partially
charged exactly to this amount.Thus you can always perfectly prepare your battery for storage, if you want to store them over a longer period
of time.
How to partially charge a battery: please follow the instructions under chapter „Programme Structure“.
We recommend to completely discharge the battery first and then put about half of the nominal capacity back into the battery. For example, a
battery with a nominal capacity of 4200mAh should be partially charged with 2100mAh.
Note: NiMH batteries can be stored for about 1-2 months without problems using this method. LiPo/LiFePo batteries can be stored for about 6
months without problems. After this time period, you should check the battery and, if necessary, put some partial charge in again if you don´t
use it regularly.
Autostart Timer: This handy feature lets you preselect when you want to start charging your battery with the QUADRA-PRO 2. The
Autostart Timer is adjustable from 0 - 99min. If you stay in the „Autostart Display“ for longer then 30sec without setting a value, the charging
process will start automatically.
Changing the charge current on the fly: The charge current can be changed on the fly by pressing INC+ or DEC- without inter-
rupting the charging process. This change is not stored. The next time you start charging, the QUADRA-PRO 2 takes the data settings of each
charge profile, stored under “Settings”.
PCS-4 (Peak Capacity System): The voltage charge curve of NiMH cells may vary considerably at the start of charging due to cell
construction. Conventional chargers interpret this incorrectly as „delta peak reached“ and terminate the charging process (false peak). The QUA-
DRA-PRO 2 has the LRP-exclusive PCS-4 which contains advanced algorithms to detect this phenomenon: This ensures reliable full charging.
PCS-4 allows the perfect full charge of all NiMH cell types by means of an adjustable delta peak and high-precision digital-filter detection of all
parameters throughout the entire charging process. The QUADRA-PRO 2 signals full charge and end of charge by an alert buzzer that sounds
for 3 minute.
Data View Function: at the end of each process (charge, discharge or cycle) you can view additional data by pressing MODE button.
Also you can access DATA VIEW from initial screen by pressing MODE button, which allows you to view (press MENU again to hop through data):
DC input voltage / Battery voltage / Charge data from last process / Discharge data / Balancing Voltages from last process
