I don't think Lithium batteries will be in my budget in the near future BUT I do plan to go with four 6 volt batteries next year which will get me to 440 amp hours.
4 six volt batteries will have 1/2 the number of cells as 4 twelve volt batteries. This will increase voltage drop under load, as each cell has to work twice as hard.
Do make sure the battery bank is wired in a balanced manner.
My next bank will be SiO2 batteries. I can squeeze in 7 100 amp-hour batteries. They can do 9C for 5 seconds, and 4C continuously.
I have one that I'm torture testing on my generator. It spins the starter far faster than the AGM it replaced.
