Pretty sure the 3rd picture doesn't work - I am no electrician , but the black wire on the right left hand side doesn't seem to do anything ?

I'm no electrician but it looks ok to me.

Pic 2 shows 4 12v batteries in parallel.

Pic 3 first creates 2 24v batteries by hooking two pairs together in series (black wires). It then connects those two in parallel in the same style as pic 3

Could be wrong.

There's a way of wiring multiple batteries to ensure a uniform load on them.
Bit anoraky, had people who did that sort of thing. But I could explain the principle to the even stupider from further up the greasy pile.

Off to Google the principle.
