I have a 2016 PW Ascent with 2 li-ion coach batteries and the engine battery. The coach batteries have 2 disconnect switches; one to disconnect the batteries, and one to disconnect the solar panel from the batteries. The engine battery has one disconnect switch. For storage, instructions are to fully charge all the batteries and then disconnect them using all three switches. This has worked well for me and in the Spring, after 4 months or so of storage, I find that the batteries still have about 80 percent charge. The only deviation to this is that I connect the coach batteries to start the generator for a half hour once every month or so. In general, I suppose how well a given battery will do depends a lot on the quality and age of the battery, so, as others have suggested, it's probably best to check them every month or so until you see how well their doing. Good luck with your new RV!
