I wonder if Tesla has thought about or is working with Phinergy, the Israel based company that is inventing the newest best batteries for electric vehicles (IMO).
I just saw that they have worked on a 50 cell pack that has moved a less energy efficient electric car (compared to Tesla's standards) 400 miles, and can actually go over 1000. Inst new more efficient batter technology needed to extend range and reduce the cost of building an electric car?
What do you guys think about Phinergy? What does Elon Musk and Tesla engineers think?
