    Thanks for sharing. I am very interested in converting to an EV. I have my eye on an 87′ MR2 without the engine installed. Anything you’d like to share as draw backs or things you would do differient in the selection on this type of car? How much were the lithium batteries you used? I have a lead in a battery PAC from an 2005 Ford Escape Hybrid. Can these battereis be used for this type of conversion? It’s a 300v PAC

      Hi Marcus,

      It is great to hear that you are considering an MR2 for an electric car conversion. It is a sporty high range electric conversion because it is so light. My pre and post conversions were 2365 to 2750 lbs. Depending on how fast I drive, I can get 70 to 100 miles on a single charge on a set of 26 kwh LiFePO4 batteries.

      My only complaint about the MR2… it is only a 2 seater. If I wanted to take my wife and son out in the electric, I can’t. We are looking to add another electric car to our family though, probably within the year.

      Regarding the Ford Escape Hybrid batteries, do you know the specs on those? I found this spec on It looks like it is a 330V pack at only about 1.8ah capacity = 330V X 1.8ah = 0.5 kwh. Unless I am missing something, you probably won’t get much range out of that pack (estimate about 0.300 kwh per mile).

      The pack that I got was around $10k and are supposed to last 2000 to 3000 cycles. See this post where I estimated the range expectancy of the battery pack to be between 133,000 to 170,000 miles. The cost savings in gas money would more than pay for the pack over the life of the batteries.

      Feel free to email me with any other questions!
