I should have mentioned that the LiFePO4
batteries can be drawn down to 20% SOC, no problem.
I found other Surrette batteries that were 2 Volt 4860 amp hours. The 1766 was a different battery
that was a start point. I applied the corrected math formula to the new batteries and that is how I got to 58.2 kwh. My idea here is to make sure I don't drain low which you obviously got, so I looked for more storage
in relation to the kwh drain. maybe with recharge in the 3-4 days at anchorage from wind
I could push it further, all depending on how much that airco worked at night. I guess what I am saying at this point is maybe with the right set up rather than looking for the 100% solution, 70%-80% is good enough with some dockside recharge time to top back up.
