This schematic above is exactly how I have my portable/modular rig setup. I have several of the Lion ut-1300 batteries wired/boxed in pairs at 24v series, each pair with a bolt-on fuse and then an Anderson SB175 1/0 cable. Each battery box is a reasonable weight for transport.
On the inverter side - I have a bus bar that has several short SB175's coming off it. This allows me to quickly plug in a single pair (24v, 105ah) of batteries, or multiple pairs depending on my needs at the time. I have rubber dust caps on all cables to ensure no shorts for cables that aren't plugged in. I just wish SB175's had a better panel-mount option rather than pigtails.
I do have to make sure batteries are charged equally, and that my SCC/battery monitors are configured for whatever Ah I'm using at the time. But that takes just a few seconds. On the solar side - I also use Anderson SB50's off the change controller (which does have a panel-mount option I found on Ebay), and an SB50 cable that breaks out to (4) PowerPole 45's. All my panels are rewired for the PP45's - which lets me quickly shift from parallel or series wiring depending on my needs (I have other 12v SCC rigs)
