Thanks, BBells. Good knowledge! As newbies, we didn't know about our existing batteries. We're wondering if the rig originally shipped with these batteries.
We're entertaining one battery option and an alternative to conventional solar panels, and can further use your knowledge and expertise ....
Weight is a definite concern for our rig. So, we're considering installing MiaSolé flex panels as a permanent solar solution. Their panels boast 16.5% efficiency, are unbreakable, and weigh far less than conventional panels. We've taken all the necessary measurements and can possibly get at least 1200w on the roof, but only if we remove the "bat" antenna. We don't watch TV, so we're not going to miss it a bit. Are you familiar with the flex solar "peel and stick" panels?
As for batteries, our first option is to purchase Clean Energy Storage's PowerGrid box that includes either a 24 or 48v 7.6kwh 330ah LiFeMnPO4 battery that has a 7-minute DOD charge to 90% capacity. The plug and play box also includes a 6K inverter, a smart charger, and mounted interconnects.
All pretty cool.

Pick up a couple 6v golf cart batteries and put them in series if you are going to replace your current battery. They cost the same, last longer and have 2-4 times the amp hours. Avoid anything that has cca on it. FYI: I have set up solar systems for campers and cabins and ham shacks for over 20 years. Don't waste your money on marine batteries.
