We just upgraded the power system on our 2019 Leisure Travel Vans Unity FX.

If you are a regular reader, you know Jen and I love to boondock, off the grid, for multiple days.

With the two AGM coach batteries we had in our Unity (we upgraded from the stock lead acid 6 volt batteries to AGM when we bought this unit in March) we were able to  stay out there for three or so days, maybe four if we had a lot of unobstructed sunlight for our 400 watts of solar panel to keep topping off those AGMs.

With the two new 100 amp Battle Born lithium batteries we just installed, we can now probably get a full week out here.

Here’s a video showing just what we did, how everything works together and how it was installed.

I want to give a strong shout out to Joe from the M53 RV and Trailer in Almont, MI. M53 RV and Trailer is a mobile tech center and Joe came right to our driveway to make sure things were working right.

For the record, here’s what we upgraded to:

  • Two 100 amp Battle Born LiFePO4 lithium batteries (replacing two deep cycle AGMs)
  • A 2000 watt Victron Multiplus Inverter/Charger (replacing the 1000 watt stock Magnum inverer that came with our RV)
  • A Victron SmartSolar Charge Controller MPPT 100|30  with Bluetooth (replacing the stick controller that came with the Magnum 1K inverter) 
  • A Victron BMV-712 Battery Monitor with Bluetooth

The Bluetooth capabilities let me monitor system performance, turn on and off the inverter, and see how much power I am consuming and how much time I have before the batteries are depleted. This is
