We went old school as well, with 8 X 6v Trojan T-105, for 900 amp hours. Being flooded lead acid, I consider about 35% of that usable (the range from 50% to 85%), although they often do top off closer to 100% full. That gives us a conservative 300 usable amp hours for $1000 or so. Longevity has not yet been tested (about a year old), but the reputation of these old school batteries is decent. Yes, I do have to water them. It is more accurate to say I have to check them. They do not seem to lose/use any water, but I put a thimble full in once I have them open.

It seems like very good bang for the buck, but it would be a step down from where you already are, Seevee.
