This invention improves on a motorized trailer by adding battery swap capability. The purpose of the invention is to extend range using electric energy provided by the swapped-in batteries and to improve energy efficiency and safety above hill climbing and braking assistance which are still a features. A rack or other removable battery holding device is integrated or retrofitted to a trailer along with a battery communication interface and power transfer means which allows connecting and disconnecting a battery set. The batteries can be replaced by recharged batteries, possibly of a different capacity and/or chemistry. The large format battery modules have a common form factor. A sending unit relays information to and from the towing vehicle to the trailer.
