1. connections / operation
The QUADRA-PRO was developed with the main objective placed on easy operation of all features. Intuitive
navigation by means of 4 buttons makes it very easy to use and the 2-line blue backlit LC display offers perfect,
reliable control of all settings and functions.
BUTTONS:

2. settings
The QUADRA-PRO allows you to save 3 individual user profiles. This means you can customize 3 personal
charge profiles individually and store them for later use. The QUADRA-PRO has 3 preset works-default settings
when shipped out: P1 (NiMH), P2 (NiCd), P3 (LiPo 2-cell). For details see the table below.
The active profile P1, P2 or P3 is displayed
in the main menu. By pressing the INC+ and
DEC- buttons you can change between the
profiles and their settings.
To reset your QUADRA-PRO to works-default
settings, proceed as follows:
• Disconnect input voltage.
• Hold down MENU button while reconnec-
ting the input voltage.

4. charge
SET Battery Type: The QUADRA-PRO 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 manufacturer, 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.
SET Charge LiPo/LiFePo Volt (pack voltage): The packs
rated voltage 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.:
5. 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 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 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
6. cycle
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 to detect the actual
quality of your packs. This prevents nasty surprises.
P3
LiPo
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
2.0A
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:
7.4V
- Initial Discharge -> Charge: 1min (if discharge was finished within 10min), otherwise 5min
1.0A
- Charge -> Discharge: 1min (if charge was finished within 10min), otherwise 5min
6.0V
Note: The „Cycle" function can of course be used for all types of cells (NiMH-NiCd-LiPo-LiFePo).
