Question Replacing house batteries

[Retired1]

Thanks Neal! I will look into the shunt. I took my Xantrax invertor out and had it gone through by a Xantrax shop and he was the one that first told me that the AGS only looks for voltage. So then called Silver Leaf and they confirmed that the AGS would no longer work with the Lithiums,

I already have the shunt and the upgraded panel to see SOC and I'm assuming it will readout with the new battery. I'm ashamed to say I have no idea where the BIM is located. Any direction there??

That may be the case depending on your setup. As I switched to Victron I have a custom solution designed by the installer of my setup, Solar Energy Systems. It probably depends on the components used and that should be checked but in @lostinfla's case with Magnum I think his Magnum AGS unit still works as it's tied to the inverter.

So, in conclusion, with the inverter and control panel compatible with lithium, and the new LiBIM installed, I should have no problems with the alternator. Are there any other potential modifications / problems I should look for?

Well, there are a few concerns you need to be aware of:

1. You'll no longer have to worry about low voltages or voltage spikes
2. You won't have to worry about getting near 50% and killing your batteries
3. You'll have to deal with increased storage and have to figure out where you put things
4. When boondocking such as at the balloon fiesta or a harvest host your GEN will charge significantly faster than those around you so you'll be annoyed by their GEN running while you have peace and quiet
5. You can have krispy kreme again since the battery weight is significantly reduced, don't share with neighbors, they have heavy batteries, be thoughtful...
6. You won't have to deal with batteries for around 10 years so you'll need to find a new hobby, or grill, or clock

That should about cover it. Did I miss anything Lithium friends?

Since lithium doesn't significantly self discharge during storage you'll have to find something else to fret about if your rig is stored in a place without hookups.

Well, going from "I really don't need lithium" to "I have all the stuff on order now" didn't take long. I'll get some pics of the conversion when I finally get around to doing it. Thanks all for the info and prodding!

@GlampDaddy needs lithium now. True.

As far as shunts go, I decided to hold off on installing one when I did my lithium conversion last month. We're three weeks into our first trip since conversion and I'm finding that occasionally checking SOC on my phone using Bluetooth from the batteries is working just fine. I don't feel the need for a separate display.
