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...

Ok one last shot at it. IMO Steve has it wrong by saying "power" has a time component. AFAIK Watts is "power" and no time, while Wh is the "energy", which is over time.
yup I did have a brain fart. I apoligise for that, but thats isn't what the main point of my post was about. it was about you trying to use CCA as some sort of power capacity for the battery. first of all why are you using a starting battery in your rv? and second the definition of CCA is
Cold cranking amps (CCA)
Starter batteries, also known as SLI (starter light ignition) are marked with CCA. The number indicates the current in ampere that the battery can deliver at –18°C (0°F). American and European norms differ slightly.
AH if we assume that the voltage is 12.0V then makes sence and is great for comparing batteries. when I first started buying batteries there was no standard and some would use reserve capacity , some would have AH but not the chart they would pick one rate and other companies would pick a different rate to make there batteries sound better.... it isnt 100% accurate but it gives you a method of comparison. I wouldnt take it for gospal that if we buy a 100 AH lead asid that we are going to get 100 ah out of it as it all depends on how you vary the voltage and current but it is an aproximation of the capacity and as long as we understand that were all good.
