Thanks to everyone for your help, input and feedback. I bit the bullet last night and bought 4 wets to experiment with.
They're 109AH G27 DC and this is an experiment - how much can I get away with and still do what I need to? So far, the results are good. Question: how long will it last? Lithium is the last add to a solar build and I'm saving the most expensive component for last. I have a portable 1kw inverter I'm playing with and will hand that off to daughter when I'm done.
I took Chances advice and reference and ran 2 strings of 12. I joined the 2 strings at the breaker post on the battery box wall. I had to completely serialize the ground because I wasn't in a position to ground the other, though I think it'll help isolate the banks a little more. Could be wrong on that. It all ties together at the end of the day - somewhere.
I installed the batteries last night and they came in bundled at 12.25. I ran my inverter to use my laptop and charge my cell phone for about 2hrs @ ~4A draw and they dropped to 12.19 when I was done. I ran the gen for about an hour and was too tired to measure but it made coffee the next morning w/o a hiccup (600W) and I was a happy camper. So far so good. I think they measured 12.19 after that. I have to start keeping better notes.
I made a 2 hr run today and measured them after a 5m rest. They registered 12.97. I've been using them for 1.5hrs @ ~4.2A(avg) draw and they currently come in at 12.76. I don't know if that's good or bad but we'll see.
Again, thanks to everyone for their help. The forum is a good place to be. Safe travels.
