After a month on the road, we've developed a pretty good idea of our ultralight EV's effective range. On level ground or rolling hills we often get 55 to 65 miles out of a single charge, while steeper hills can knock us down 40 to 45 miles. These are pretty good numbers for a battery pack with a total capacity of around 1.4 kW, but our vehicle is a far cry from a full-blown automobile, both in terms of comfort and speed. Once the batteries are drained, it takes four hours for a full recharge. We rarely, however, need to stop and charge for the full four hours, because we have created a routine that uses repeated partial charges thought the day.
