I want to build an electric push trailer. I'm a pretty big guy, and would like to use the trailer to haul a couple hundred pounds of gear along dirt roads and offroad to my campsite. I'm thinking I would probably need two 48v hubs for that kind of load.
Because batteries can only hold a limited charge, I want to build a generator that can deliver the required power to drive the hubs, and charge the battery. I would not need a huge battery capacity, since I'll be able to run the engine most of the time. But I would need the batteries when travelling through areas where people might not appreciate the noise.
Has anyone had success using a generator? I can buy a generator off the shelf, but I also have several small engines, from 3.5-10hp. And with a homemade setup, I'd be able to make the trailer like a go-kart, with the engine driving the wheels directly, in case something goes wrong with my electrical setup.
