This week I was investigating companies that do battery upgrades on older Prius models in the hopes of finding a company that was making a battery upgrade for the 2012 PiP. While I love my PiP, I do have range envy over the Chevy Volt. Thirteen miles goes pretty quickly! I sent an email to Plug-in Supply, not expecting to really hear anything positive. To my surprise here is the response from Robb Protheroe, President of Plug-in Supply, Inc.: "We are working on a system for your car now. We will have something in 2 months. Regards Robb" This offers some interesting possibilities. What do others out there think of this?
