      Moving to Lithium: LiFePO4

      I replaced our house battery and updated all the charging cables, new charge controller.

       

      I used a Victron 12-12 30A non-isolated converter, and a 100ah lifepo4 battery.

       

      Also used a ‘94 Jaguar 120A alternator that barely fits, uses the same plug on back. Then put on new larger power/ground cables to replace the small ones that came on it. Used 6awg welding cable for the Victron and house battery runs. Had to get a nice crimping setup for all the connections.

      How far are things separated? House battery, engine battery and Dc2Dc charger?

      Moving to Lithium: LiFePO4

      My old lead acid coach battery is 10 years old and definitely on the way out… I’d like to swap in a 150AH LiFePO4 but sounds like adding a DC to DC charger is likely a must (my original alternator is rated just 70A, so I need to limit the charge, since the new battery can pull a lot of amps during charging, if not regulated). 
       

      I like what I’m reading about the basic Victron 18A unit, but I’m not sure how/where I’ll mount it cause it’s not super small at 7.3” x 5.1” x 2.8” ! The Warrior’s battery box does not have room for sure. I’d like to just put this thing under the hood, near where the isolator/solenoid is now (which will no longer be needed), but the space available there is pretty small and irregular (not to mention all the engine heat). 

       

      Anybody done a similar project recently and have a suggestion? (Or, are there LiFePO4 batteries that will self-limit their own charging current possibly? Back to Google…)
