Truck Battery, interesting product.
I would be suggesting looking very local, not the kind of thing you will be able to ship around easily because of the weight, not to mention the packaging and shipping issues you would face.
I mean shipping by the pallet or even container/truckload wouldn't be a major issue for delivery, but not the kind of thing you would want to try and get one of shipped, or even ship yourself to a customer I wouldn't think.
At least I wouldn't : )
