There's a great deal of attention to lithium ion batteries because they are lighter and deliver more power than traditional lead acid batteries. But there are a number of companies making improvements on lead acid chemistry and using these batteries in fleet trucks. This converted van from Vantage uses both lead acid and lithium battery packs to get a 40- to 80-mile range. The top speed is only about 30 miles per hour, but it's street legal and is suitable for in-town driving.
