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...

They say the 120AH is "nominal" so the real 20hr rate capacity could be that 113AH IF they are full at resting 13.6v like the BBs. I don't know.
You could get the battery as full as it can get, and wait till next day to get the resting voltage, and divide the 1536 by that to get the AH to use as "full" with a monitor.
The charging voltage is 30a, which would be their recommended for long life I suppose. You can use higher amp charging to save gen time if that is more important than max lifetime cycles.
Their sales blurb says "four times the power", but it is clear that they mean "energy" , not "power". Their Forbes link guy has a "power density" notion and an "energy density" idea too.
He has the energy density being what saves weight (correct) and that is what the blurb probably means by "four times---". Tried to make sense of that before, but since the LFP is only 1/3 the weight of an AGM same AH, it is hard to follow. Might not include casing and BMS etc, just the cells?
EDIT--105AH AGM =66 lbs. Lynx 120AH = 35 lbs so where is the energy density "four times" ? It is only half the weight. (another thing we are not supposed to ask about? )
"Power density" seems to be like CCA the way he uses it, so he just means higher power density means more power (I guess)
Near as I can tell, you are not supposed to worry about all that, and just use the battery, but stay above that lower knee, playing it safe by staying higher above the lower knee, since your monitor is only going to be a rough guide to the SOC. ? YMMV.
