Balanced Charging X's 4 6V Batteries
As I've recently started a campaign returning to basics on the care and feeding of my soon to be replaces X's 4 L16's - I have a follow up question. I've confirmed proper wiring to yield parallel/s...

The diagram above will not work with GC-2 (6 volt) batteries.
I believe that you're referring to the two diagrams that "red31" posted above your earlier post.
The left diagram above your earlier post represents four (4) 12 volt batteries connected in parallel in a balanced way.
The right diagram above your earlier post represents eight (8) 6 volt batteries connected in series-parallel to makeup four (4) "12 volt batteries" connected in parallel in a balanced way. (Notice the little black line at an angle in each black outline box - that outline box represents a couple of 6 volt batteries interconnected in series.)
Connecting batteries together in a "balanced way" is not Rocket Science. All it means is that the total wire length (regardless of what wire size is used) going all the way around the loop from each battery's plus terminal to it's minus terminal is the same length for each battery. With a balanced setup, this "same loop length" for each battery will be the identical for every battery whether the battery bank is being discharged while feeding the RV's total electrical load or being charged while being fed by the RV's charging equipment.
The object is for all battery system cabling voltage drops (regardless of cabling gage size used) from currents going to/from each battery to be the same - as seen by each battery.
Balancing the battery bank this way is of course external balancing ... and does not ensure that internal battery construction and chemistry maintains balance at all times internally between the cells within each battery during the life of the battery.
