The QUADRA PRO 3 allows you to save 5 individual user profiles. This means you can customize 3 personal charge profiles
individually and store them for later use. The QUADRA PRO 3 has 5 preset works-default settings when shipped out as shown
in this table:
SET Battery Type: The QUADRA PRO 3 can charge pretty much any type of cell (LiPo, LiFePo, LiIo, NiMH, NiCd, Pb) and
incorporates the designated charge algorithms for each particular cell type for best performance, reliability and safety.
Lixx + Pb
 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. allowed charging voltage per cell
(for example, LiPo 4.2V and LiFePo 3.7V), the charger automatically reduces the charging current till the
battery is fully charged.
NiMH/NiCd
 charging with constant current + delta-peak detection. This is the most popular charging method for
NiMH/NiCd-batteries in competition.
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!
DC INPUT: connect to a suitable DC source with 1115V, using the supplied connection wire.
Caution: Be careful with correct polarity!
- Red = Plus / Black = Minus
AC INPUT: connect to main power with 100-240VAC
Caution: Do not alter the wire or connector as this will
void your warranty!
balancing function
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 QUADRA PRO 3 contains an integrated high-performance balancer for 2S to 6S Lithium based (LiPo, LiFePo, LiIo) battery
packs using EHR balancing connector. Please refer to drawing (also like that on charger) for correct polarity, basically minus
(black wire) is always on the far right side of the plug as shown on drawing.
The balancer equalises the cells, during charge- and balance-function, which
results in higher performance and higher cycle-life.
6S
Caution: Avoid incorrect connection as in the worst case this may result in
damage to the battery and/or charger!
discharge
The adjustable discharge circuit (0.1 to 1.0A) can be used for 1-14 cell NiMH/NiCd- and 1-6 cell Lixx/Pb-packs. The QUADRA
PRO 3 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 3 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.
recommended settings
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
Always follow the cell manufacturers charge-/usage-recommendations, never use batteries outside their specifications!

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 3 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.
The crossed-out wheeled bin means that within the European Union the product must be taken to seperate
collection at the product end-of-life. Do not dispose of these products as unsorted municipal waste.
troubleshooting
Special features
The QUADRA PRO 3 is protected against faults and operator errors by the Multi-Protection-System.
Faults/Errors are displayed on the LCD screen and some faults/errors may interrupt the charging process
to protect the charger and the battery.
Storage Charge Mode: Never store your batteries completely empty as this will harm them and lower their performance. Due to this fact,
the QUADRA PRO 3 features a „Storage charge“ mode. With this function, you can set a fixed voltage (vor Lixx batteries) or fixed capacity (for
Nixx batteries) value and the battery will be partially charged or discharged (in case of Lixx) exactly to this level. Thus you can always perfectly
prepare your battery for storage, if you want to store them over a longer period of time.
How to do the storage charging of your battery: please follow the instructions under chapter „Programme Structure“.
The error messages are as follows:
ERROR-MESSAGES
POSSIBLE CAUSES
Our recommendations:
- NiMH/NiCd cells: - LiPo/LiFePo/LiIo cells:
- No battery connected?
- Wrong battery polarity, bad contact?
- Defective battery?
- Wrong LiPo-cell quantity?
CAUTION
Battery Error
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 charge in again!
- Input voltage too low/switched off (<11.0V on DC input)
- Bad contact on input clamps?
INTERRUPT

Autostart Timer: This handy feature lets you preselect when you want to start charging your battery with the QUADRA PRO 3. 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.
- Input voltage too high (>15.0V on DC input)
