If you have lithium batteries (LiFePO4), the usual recommendation for winter storage is a bit different from lead-acid batteries. Most lithium battery manufacturers suggest storing them at about 40–60% state of charge rather than keeping them fully charged all winter. A common approach is: • Charge the batteries to around 50–60% • Turn off the main battery disconnect (or disconnect the batteries) • Avoid leaving them on a continuous 120V charger unless the charger has a proper lithium storage/float mode Lithium batteries have very low self-discharge, so they can usually sit for several months without any problem. The main thing is to prevent parasitic loads from slowly draining them. Also, if temperatures get very cold, it's best not to charge lithium batteries below freezing unless the battery has a built-in heating system. Many RV owners simply disconnect the batteries and check the charge level once or twice during the winter.

Hi everyone, I just joined the forum and wanted to introduce myself. I’ve been interested in travel trailers and RV systems for a while and recently started learning more about the technical side of things, especially electrical setups, batteries, and solar systems. I don’t own an Oliver yet, but I’ve been researching different trailer options and the Oliver models caught my attention because of their fiberglass construction and overall build quality. I’m also really interested in how people are setting up lithium batteries, solar charging, and energy management for off-grid camping. There seems to be a lot of great knowledge in this community, so I’m looking forward to learning from everyone here. Thanks for having me and I’m excited to be part of the forum.
