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...

I have seen that where they say it maintains the same "capacity" But it still runs for less time the higher the draw.
They say 1C for an hour is the same "capacity" as 0.05C for 20 hrs like using RC instead of AH.
Peukert has it running for less time the higher the draw too, with fewer AH at the higher draws
Then they start using "twice the power" or more energy density. Makes me feel I am being flim-flammed.
However, after some digging, it turns out they just mean it can do the high draw for longer than Brand X, not that it does not take less time than a lower draw would.
Can't help it--as soon as I see "power" and "energy" in the advertisement I get all paranoid they are messing with my mind. Just give me my Trimetric monitor and AHs and let me go camping and everything will come out right :)
except the internet is full of people who have doen 1C tests on LiFePo4 and ran at full 1C for 58 min. doesnt seam like much of a Peukert effect. well I guess it was two min less time, but thats when the BMS shut off so it might have gone the full 60 min , or maybe they were just good cells with 5 or so extra AH... so at least for prismatic cells the 1C rate is actualy 1C. I dont know what 10C would result in but I cant imagin it would be far off, but another useless number unless your driving a tesla ;)
