Electrical wiring question

[Ocracoke]

To take it to the extreme one wheel free spinning while one at stall would result in one ESC seeing the majority of the voltage (And promptly breaking itself).

This was along the lines of the issue I was thinking of, hence the original post though I was perhaps thinking about it from the wrong angle (I was concerned about the arrangement from an amperage perspective). So OK, that idea is out of the window. This leads me back to my question about rule 7.5 and wherever it applies to the whole robot or per battery pack when wired in series.

7.5 is functionally a voltage limit but phrased by cell count. If you are using 2 batteries you wouldn't be wiring them in series, they would be separate circuits (With a max of 12 cells in series so fine).

Basically as long as you aren't arranging your battery packs in any way that puts more than 12S in series you're fine. You could have 6 12S packs and as long as they are all in parallel it's fine.
