Interesting looking at the specs. The RV application for Li-Ion is a bit different than the EV application (just look at the max current draws, EV limits are much higher).

I would imagine those differences mean RV's will get a different chemistry mix and that the batteries will last a bit longer.

Yes, chemistry is very different which is what makes it a lot safer as far as fires go. For RV use, this works great because power demands are relatively low, so the typical 1C charging and discharging rates are enough. For an electric car that would never be enough power. On hybrid cars I’ve seen 0.5 kWh batteries working at up to ~ 20 kW which is an order of magnitude higher than needed for RV use.

The biggest problem I see is that the cost of these RV lithium batteries is still a lot higher per kWh than what the auto industry is paying for theirs.
