As someone who owns a kia soul ev and has had to have the battery replaced, you can't have too much range. A lot of people are looking at 300 miles of range and thinking they don't need more. Well, it's only 300 miles on the day you buy it and only goes down over time or with cold weather. The key thing to remember IMO............ The bigger the battery pack the less you will cycle through your batteries so the longer it will last.
