balanced battery cables

It seems obvious but is it?

We have 4 6V GSs in series-parallel with the two 12V pairs connected as in the diagram below. (Which I unashamedly copied from one of Painotuna's posts.)

However, both the load and the charging cables are LARGE, (000). Add the series-parallel cables they really fill up the lugs.

Here is the question:

If I move say just the charging lines to the other pair of the parallel + and - terminals is it still properly balanced?

    Between the house feed, solar charger, Magnum Inverter/Charger, external sense, temp sense, and the watering system, it just got too cluttered. Now there is the watering manifold, temp sense, and 2ea. 4/0. All else is in a cable raceway


    Not a Winne, but close; 32' Itasca Horizon. Being only 32' there is not really anywhere else to put them. We spend a lot of time in the rig and carry too much stuff!
    Its still a Winnebago product with the same floor layout. At the base of my bed, there is a boxed area about 10" deep that is all cable routing, the EMS, breaker panels, and the ram for the slides have more than enough room to mount the surge protector as well as DC distribution, including the Shunt for the Magnum, takes up zero storage space. I have a friend with a little newer 32T Journey and pretty sure that access box is in his too.

    Its going to be the same just like BB_TX said. But why?? Are the terminals different?? You will still have two wires connected to one terminal.


    Now I have three wires (Load, Charger, Jumper) to one terminal and one (the jumper) to the other.

    Pianotuna; Not enough room for buss bars. The 4 GCs are in the upper tray.

    Hi,

    One solution is to have a buss bar for the twelve volt connections. That leaves a single cable going to the jar.

    Yes, it is not going to care which of the two terminals of each pair you connect the charging lines to. The electrons are going to flow to the right place.
