Serum and BrianG, thanks for your help.
I will use the CellPro DSM LVC but I guess the connections will be the same.
Also this is what I got from FLMdirect support:
"Here is how to wire it.

You will need our 2mm pigtail.

Pin 1 is black and should connect to your speed control black.
Pin 2 should connect to 4V Node 1.
Pin 3 should connect to Red of the lower pack. (Center tap in the speed
control)
Pin 4 should connect to 12V Node 1 on the upper pack.
Pin 5 is red and should connect to the red of the speed control (16V)

You can easily verify that you wired correctly before connected the DPM.

On the 2mm Cell Pro pigtail, you should verify the following voltages. Put
the Negative probe of your meter to speed control ground.

Pin 1 (Black) is 0V
Pin 2 (White) is 4V
Pin 3 (White) is 8V
Pin 4 (White) is 12V
Pine 5 (Red) is 16V

Once you have the pigtail reading the above voltages, plug it into the DPM
and do the setup."

Now I just need to find the connectors here in Sweden...
