Did you set your solar controller to Li Batteries? My Renogy controller has separate settings for charging Li Batteries as opposed to Flooded batteries. 6ah draw canít be anything too big, possibly all your 12v items together equaling that. Iím assuming that reading is as you are currently using the camper and that everything isnít shut down? If your still not charging there is an issue between the controller and batteries because the panels seem to be providing plenty of voltage.
