Just don’t buy Lion Energy’s Lithium as the have deceptive advertising by saying their Lithium is 100AH when really it’s only 85-90AH so I would go with Battle Born.

I think he worded that oddly. For starts however, LFP batteries come in various AH ratings just like AGM. He really should be comparing apples to apples in the AH department. 400AHs of LFP is about equal in usable capacity to 800AHs of AGM. Yep, AGM will cost less up front and even in the medium term. But AGMS weigh a ton compared to LFP. For fulltimers this could be a critical issue as many full timers are typically at or over their trailer GVWR when you start adding in sought after fulltimer upgrades like solar and batteries among other things. When you are loaded down CCC becomes a real issue. In that instance LFP, being lightweight compared to AGM or SLA, becomes cost effective when you absolutely have to carry everything else. Weekend warriors simply don't have that issue. According the Keystone, "most Montana owners" carry an average 900 lbs of gear and they build their trailers to fit that demographic first, then build in extra to be competitive with the SOBs. So with only 900 lbs of cargo, and a rating upwards 3000 to 3500 give or take, 400 lbs of batteries to run stuff is no real biggie. But when you are hauling everything you own... that 400 lbs of batteries could be a deal breaker, so the ~275 lbs savings with LFP can be worthwhile. YMMV as they say.
