Well if their 250AH is priced anything like their 100AH it will be around $1250 to $1500 per battery. I can sure buy a lot of lead acid batteries for what a couple or three of the lithium will cost. You would have to be a hard core boondocker for them to pay for themselves.
It's all about life-cycle cost. When you factor in the life span of the Lithium-Ion vs the lead acid the cost comes out almost the same. (Also helps to factor in the power available for use - generally a smaller Ah Lithium-Ion will give the same usable power as a higher Ah lead acid.) However, if you not keeping your RV long enough to amortize the cost of the Lithium-Ion it becomes a moot point.
