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 bet this is to do with those nasty watts things again :(
A 150Ah, 48V battery bank has the same storage capacity as a 12V, 600Ah bank (using the T1275's as an example). Watts.
I am having all kinds of trouble with AH and the higher voltages :(
If the 12v inverter draws 150a with the MW on a 12v 300AH battery bank (the two 12s in parallel), we know how that works.
Now if the two 12s were in series for a 24v bank of 150AH, and you had a 24v inverter, the inverter would draw 75a ??? but you can't run the MW any longer than you could with the 12v set-up????
So it is just about wiring? How is it any easier on the batteries with the 24v version?
