Hi. Mr. Squirrel.

That's what I was really curious about. In my horrible laymens terms......

What, if any, added "load" or resistance would occur in the 2nd
scenario? (assuming x amps depletion is split evenly between each
battery) But. If all is sized right, it doesn't matter. Just thinking
about saving a little dough in the solar panel dept.

I bet it's nothing more than a "hair" advantage if any. And maybe a
red one at that.   ;)

I will research string theory.   ;)  If it's anything like Pretzel
Logic, I'm in!

Neil.
