  My Lifepo4 Install After 4 Yrs

  Posted by DON on January 5, 2026 at 8:12 am

  96 Liberty XL40′ 12v Classic

  It’s been 4 yrs and 18,000 miles since I switched from 3 Lifeline AGMs to 3 Renogy Lithium/Lifepo4 house batteries. I have had zero issues with them or my simple easy inexpensive drop-in install.

  I recently did a capacity test on them, and they still have 100% capacity.

  How do I keep them charged?

  1) with dual Magnum MS2812 inverter/chargers that I installed almost 9 yrs ago. I programmed the remotes using the CC/CV & CUSTOM feature for the Lifepo4 chemistry and easily make adjustments to my custom charging profiles to suit our needs.

  or

  2) with the Prevost supplied air cooled 12v/145amp house alternator with its built-in voltage regulator that’s belt driven by the 90* gearbox.

  The only modifications I did were:

  1) Replaced the small Liberty installed battery isolator, connects the gen bat with these Lifepo4 house bats, with a normally open continuous duty 12v/300amp solenoid/relay. ($20), I ran a wire to trigger it to close when the ignition switch is in the ON position. The Lifepo4 house batts ARE connected to the lead acid gen battery, and the 12v alternator anytime the Detroit engine is running. Works perfectly.

  For cold wx operations:

  2) Added a 12v heat pad to each of the 3 house batteries ($30), a 3 gang switch panel ($20), and a thermostat ($20).

  When we are not using the bus, we store it unplugged with the house Lifepo4 batteries at 50% state of charge (13.1v) as recommended for maximum battery life. I do not have a state of charge gauge. I go by their resting voltage. My Lifepo4 batteries have Bluetooth which we choose NOT to utilize because there is no need.

  Your results may vary.

  Here’s the thread I did on PC 4 yrs ago about my install. The pics I originally posted in the thread have disappeared????? so I’ll post more.

  Also, some of my original post and my replies in this Jan of 2022 thread are in BOLD, some are not. For some reason? most of “my” replies in the thread have other peoples names given to them? like Jon, Bernard, Mike, & Ken, not my name (Don).

  I WISH THE OWNERS OF THIS FORUM WOULD FIX THESE PROBLEMS
