2 x 24v - 6v battery bank configuration

[gjlsan]

I'm trying to configure two 24v battery bank of 8-6v s-550 batteries. Is the diagram correct?

Technically yes but you are missing a fuse between the Battery and Controller. You want two fuses mounted directly on the Battery Term Post. One for the Controller, and one for the Load (Inverter) .

If you must use parallel battery configuration Click This Link and use method 2. One thing missing in Smart Gauge method 2 is where to connect the charge side. It goes on the opposite corners.

Although not exactly what you are doing, the drawing below is how the fuses are placed.
