parallel or separate?

Did up a simple wiring plan for the gel-cell dual-battery power tank...



I like how the testing circuit can be switched to measure one battery only.

But the more I thought about it, I didn't like it. A couple of major concerns emerged.

The negative charging junction, while slick in its placement ahead of the selector switch, meant that I'd need heavy gauge wiring in many more places. Ugh.

If the dual battery system proved too heavy and I'd built a solution wherein they were tied together, then it would be a significant redesign effort to separate.

And finally I remembered seeing flickered or pulsing in my red LED light table while connected to a common power source. Coming from the dew heater controller and its pulse width modulation circuit. I don't want this distracting effect.

So, maybe, I should keep it simple. Segregated, separated batteries... But still in the same cooler buggy, of course!
