Upgrading to Lithium with Solar...
Fellow RVers, My first post here, so please excuse any ignorance on my part. I have a 2012 R-Vision Crossover, 19' travel trailer. I have been using a 160w roof-top solar panel to charge two 12...

Our Advanced RV unit came with a 600 Ah pack of Li batteries. They power pretty much everything including cooking - there is no propane, which is a real advantage.
Their setup includes 1) A second alternator on the engine to deliver the correct charging voltage, 2) A temperature sensor for each cell with an electronic readout, 3) An overheat shutoff, and 4) A battery pack heater.
They warn that charging the batteries when the cell temps are less that 32F or storing the batteries at temps below 14F.
There are Li batteries that use a different chemistry that are less temperature sensitive but these may have other drawbacks.
For your needs, I think you would be better served with a pair of true deep cycle AGM 6 or 12 V batteries.
