I am figuring out what battery voltage would be best performance and pocketbook wise, and they are a little different. For 100 aH LiFePO4 batteries, 120V would cost ~$4,600 (before shipping and cables), and 156V would cost ~$5900. Now, I can either save for another two months and buy the 11 extra battery packs (which will probably happen next spring).

But I was thinking, what if I bought 3 12V deep cycle batteries and could use a relay to switch them in when I needed some more power? Yet could disconnect them when cruising down the highway.
