LFP on Shore Power with Inverter/charger?
An inverter/charger requires that you have a battery connected (or some 12v source) so it will supply any 12v to the RV. (Unlike a converter that will do 12v with no battery) Some say not to float...

Sometimes we tend to over think things...I can remember back when I ran a battery until the tv screen started to shrink,then I charged it..lol..Never new better!..Now things are quite different in the way I use my batteries....
Right now my battery is going on the 7th day of running my Engel compressor fridge/freezer and the SOC is above 50%,something I couldn't do with my $200 agm nor could I put 50ah back into it in less than 3 hours,something I was after for boondocking which is 100% what I do...The weight of 32lbs is quite manageable compared to over double that for a lead acid of comparable size which is important if the wife needs to do anything with the battery...I also use it in a smart battery box in my truck camper that also serves as a step lol..and I can bring it in the house with ease to run whatever if the power goes out...So yes,I'm quite happy I made the change to Lithium for those reasons...
As for exact numbers for the Victron SOC or Voltage to SOC or exact amp hours,I don't really care as long as I have a guide to approximate numbers and the good thing is,if I somehow run it until the BMS shuts it down,it's really no big deal with lifepo4 cells...
As it turns out with the failing Bluetooth and the partial refund,I feel good about the price I paid for a 120ah lifepo4 battery and especially the support/2 day shipping and no tax...
