You can easily save 30% off your commute cost simply by driving slower. What does 30% mean to you?  If it means $30/month, that’s $360/year, or $3600 over the life of the car (assuming a 10 year life) I collected some driving and energy usage data in my electric MR2 and confirmed that by simply [...]

It powers: cabin lights headlights instrumentation such as the “fuel” gauge ignition circuit that starts [...]

  The 45 cell LiFePO4 battery pack in my electric MR2 costs $10,500. A Battery Management System (BMS) can easily cost another $1200. If you are considering a set of Lithium batteries for your conversion, should you invest in a BMS to protect your batteries or not? I chose not to, and it has served [...]
