I am actively trying to figure out how to upgrade our house batteries (2-6v AGMs) to Lithium. I’ve purchased two of the Lion Energy UT 1300 lithium batteries. I know I have the Freedom X 1200 inverter. But I can’t figure out where the charger is located? I assume there is one. Has anyone done this upgrade?<br/><br/>I’m also considering putting the lithium batteries under the bed...
