Measuring V loss during charging
I know that a discharged battery can pull down the voltage at the charger. I was trying to measure voltage loss in my converter wiring, switches, etc. The two 105 AH batteries were 12.13v prior to ...

As mentioned earlier, fuse holders are also high R sometimes. However they are like short skinny wire AFAIK. That is, you can get away with skinny wire if it is short, but not if it is long.
You also have to consider the circumstances. I got my 13.8v Parallax 7355 doing great but I only use it on shore power, so who cares if it does better? Time doesn't matter like with generator charging. (I was thinking of swapping out that 7355 for a higher voltage charger, in which case that job would have been worth it)
If you use a deck mount charger up front, by-passing all the high R stuff, it will do great anyway. IAW you can waste your effort improving things that don't matter in the actual scenario.
