The Latest Range Info.

With batteries heated to 80 deg. I get a solid 40 mi. range now. I'm pleased with this new number, but slightly perturbed over the previously noted voltage drop when needing high currents (200-300A). I now find that my 120V only charger is the limiting factor for opportunity charging. So- what would I do differently? Shop in earnest for the best price on LiFePO4 batteries and buy a 120/240V charger.
