You may be correct. It would take someone with great electrical theory skills AND detailed knowledge of the w163 scheme to advise you well.
I just know that my 2nd Gen 1997 Dodge Ram Cummins truck has 2 large batteries under the hood, and I never seem to run out of power !
Now, I did swap them to same oem size of "Marine / Starting Battery" which is a lead acid deep cycle hybrid, like an RV might run.
Waaaay better than 2 starting batteries.
