So the batteries are still considered fully charged?Re: Xantrex and Lithium Battery setupMany thanks.Xantrex and Lithium Battery setupI have a van conversion with solar+two 250amp lithium (Battleborn) batteries. The Xantrex is a 3012 3000w Freedom. When on shore charge I turn the inverter on and it charges up to 14.1v. All seems fine and dandy. Next day I will check it and it is at 13.5v. I have a secondary alternator and it charges as well (when moving, obviously). It seems to me that the charge should remain elevated and not drop. There is nothing on currently except of course the inverter and the digital readout for the microwave. Nothing else. Frig is off. I wish I understood the electronics of this setup better.
