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?

I used four 12V batteries. We can also calculate with 6V batteries.
1800W/12V = 150A
1800W/24V = 75A
Each battery in the 12V system supplies 150A/2 strings = 75A.
Each battery in the 24V system supplies 75A/1 string = 75A
If you use 12V batteries, each battery supplies 37.5A.
If you use 6V batteries, each battery supplies 75A.
In either system, each battery supplies the exact same power (1800W/4).

Yeah, that's wishful thinking. In the case of 4 batteries and a 150A 12V load or 75A 24V load, each battery will put out 37.5A, no matter which configuration.
1800w/24v=75a.
4 6v batteries in series will share the load so...
75/4 = 18.75a.
No?
