4@12v = 24v
I'm installing 4 -12v AGM batteries to power a 24v inverter. This is my first choice for wiring: and my second: Any pros or cons to either one?

Interesting. Contact resistance is much higher than the wire resistance in the amount of wire it takes to connect batteries. #2 wire has approx .016 per 100 ft. I bet in a typical battery installation where the connections haven't been serviced often the contact resistance can be .025 ohms or more. JMHO
