Saw one of these in a Car Repair yard in New Castle PA…
Looked like a powered truck with car battterys on it…Operater said it took 8 hours to charge and could pull 20 cars
Battery-powered shop switchers have been around for a while and seem to be found in car shops, industries, and other places where they are used in light duty and not very frequently. The long charging time is a major limitation to more widespread use.
