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 c 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.

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.

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 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.

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

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.

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).
