they should sell direct. I'd look at the MPL-90 battery, its a sealed deep cycle battery 12 v 90 aH. Make sure and ask for the flag terminal, the post terminals are too small for 2/0 cable. We've used them on grid tie w/ battery backup, and off grid stuff that needed sealed batteries. They have cycle life charts, so you can compare them to other batteries. I recall them having 350 to 400 cycles at 80% DOD, not up with a golf cart battery or L16, but really good for the small sealed battery realm. Definitely will outlast the Optima in deep cycling. R.
