Thanks for all the great info. Battery is a 12V. Says it right on top after wiping it off. For now, it is used a daily driver for my 3/4 mile commute and general around town. Truck tops out at about 50mph so no freeway or long trips. Eventually, I would like to have gears changed (?) so I could take it on the highway.
As for long term plans, still trying to figure that out... So many different directions one can go with these great trucks.
