Expert Reply:
The SMI DUO part # SM99251 that you referenced does use the vehicle battery so it would drain the battery after prolonged use. What a lot of people do to combat this is run a 10 gauge wire from the 12-volt accessory circuit of the 7-way on the tow vehicle to the battery on the towed vehicle to keep it topped off while towing.
