We should be clear that 200AH of SiO2 does not equate to four 6s, except for the high draws. You still need AH for regular RV draws and for that work 200 is not the same as 460!
That is why I needed the second battery even though the one batt could do the high draws. Not enough AH for the regular camping for a weekend in this case.
Same thing could happen to somebody buying a 100AH LFP. Doesn't matter what it can do for features--it is still only 100AH so if you need more AH for the regular stuff it is very expensive to have to get a second one just for that work.
I tried a work- around for that in one of my set-ups, by having the inverter on just the one batt and have cheaper regular batts in a separate bank for the regular stuff.
So of course the regular stuff bank got low, but I could not tap into the inverter's batt to get more AH to help run the regular stuff. Better to have one big bank that does it all. (Such as in the Class C with four 6s)
Just to be clear and not confuse anybody.
