48 volt LI battery from Johnson Controls

I would not put a vehicle LI battery in a RV. These batts are a lot more volatile, and require cooling, than LI batts for RV's. These are meant as a cheaper, lighter alternative to present hybrid car batteries. The specific chemistry you want for RV's is LiFePo4.

Yeah, right - I'll rush right out and buy one!

Just needs a 48v inverter to make your 120v and you are in business. You need a converter to make your 12v from that.
