K4003 Powersupply

Hello Forum Members!
I just found a K4003 kit that my father had assembled years ago. Looking though the manual I noticed that the Kit is powered via AC but could be powered by two DC batteries hooked up in a special semi-series configuration. I have a 12volt car battery that I would like to power it with. How would I power it with only 1 battery?

Regards

This is NOT possible.
You need 2 batteries with exact the same output voltage -> not possible.
