I believe otrfun has nailed it!
My sense is these purported LFP chargers are mostly meant to satisfy the RV OEM market’s LFP upgrade option $$…for plug & play folks who don't want to be informed with a deeper understanding LFP, or their charging…
Personally, I go with a conventional PD with tethered Charge Wizard option (because, why not charge at 14..4v??) while attending the last 20 or so minutes of charge cycle (cell balancing followed by charger shutdown), especially considering how relatively infrequent a full charge with LFP is really needed…
