A short road trip was long overdue, and our 10th wedding anniversary provided the perfect opportunity to get out of town. I include the shot above mainly as a way of gloating over the ample trunk room, despite the space occupied by the batteries.

The drive is only about 25 percent of my projected range, and the needle on […]

Battery chemistry is a mysterious and arcane science that dates back to ancient Iraq, where theory holds that the Baghdad Battery was used to electroplate gold onto silver and possibly used to power ancient light bulbs. Of all the subject matter I’ve grappled with during this EV conversion project, battery technology has been the most […]
