Converting house batteries to Lithium-Ion
Time to replace the house batteries  in my 2000 U320, and I would like to switch to lithium-ion for the longevity. I found a source where I can acquire them for a reasonable price, but can't seem to locate any information as to what changes will...

When you say Lithium ion, what chemistry are they? 
Lithium Iron Phosphate, LiPO, are what most of us are using and are considered the safest chemistry.

Also What type of batteries?  Are they drop in replacement like Battle Born or homemade ones.  The answers depend on many different factors.

Post up what your coach has as in inverter and any solar or what nots..

We can start with the basics. What size bank are you planning and have you done any measurements of use? Do you have a monitoring system now?

Start us from the beginning and...

A lithium bank has to have a good bms to work. Or it could be a short visit in your coach. I looked for a long time at them, planned on building my own system, then bought a coach that already had a professional install with Victron in it. AM...

Just to clarify the technical details, LiPo is lithium polymer (think cell phones, "hoverboards", etc.) and is known to be somewhat unstable in...

You don't want to create a Frankenstein rig like I did. Home brew rigs are not as maintainable due to the non-standard configurations. It is harder to sell a rig with a home-brew electrical system. That said, I just purchased a lightly used Tesla...

After all my research and experience with a few manufacturers, I'd have to say VIctron Multiplus Inverter/Chargers is a really great way to go. Probably a 3000 for your rig. Which is what we used in our 2003 U295, A very simple swap. If you're an...

Me too, running a 21 kwh leaf gen 2 battery pack at 48 volts. It's in the S&B garage so I can monitor it. Much easier on the 7.2 kwh BattleBorn 12 volt system in the coach, set it and forget it.
But used EV batteries are getting so cheap, hard to...
