Yup, 4 100ah LifePo4’s in parallel would provide 400ah (under even high loads), assuming they’re discharged from 100% to 0% SOC (and well balanced). Some might recommend only discharging to 10-20% for max longevity, which nets 360-320ah.
However, a set of 4 GC2’s would only net approx. 210ah (not 420ah) discharging from 100% to 50% (recommended for lead cells) under relatively low load. Also, under very high loads GC2’s will very likely stumble and not provide the full 210ah.
LifePo4 don’t off-gas, so no worries about placing them inside the living area of a camper.
As for the price, well, as they say, if it looks too good to be true, it probably is :)
