Are you correcting for usable capacity in your prices? 50% DoD was typical for lead acid last I checked vs 85% for LiFePO4 (or 100% if you're happy with it lasting as long as lead acid at 50%) As to fraud, I've seen at least four batteries perform as advertised. Also a 5x disparity in prices between different shops is entirely consistent. Prices have been dropping rapidly and there are enough people who go 'oh yeah, that was about right 3 years ago'. Plus retailers may have paid several times current retail for their stock if it's a year or two old and was bought at prices that hadn't been updated for a year.
