Winterize Lithium Battery

[RDTC]

Removed my 3 lithium batteries for the winter. Store them in the basement. Installed 1 sealed lead acid battery.

To manage charging. I turned the Victron Multiplus charger off. Turned the OEM converter/charger on.

5th Wheel is stored in a Pole Barn. Over the winter, typically work on 5th Wheel upgrades, use the TV when in the barn, and use the 5th Wheel wifi. Nice to have a battery installed so I can operate devices in the 5th Wheel.

This winter's project is to clean up any water lines I have access to in the basement area. Home running lines, adding valves to each line, and reorganising. Similar to what I did with the electrical.

You might check you brand but Renogy calls for a 55% charge when storing the lithium over winter or other longer period for best lifetime. I think I have seen others post that some other brands also storing at less than full state of charge.
