I'm thinking about using a set of 4 or 5 lead acid batteries in series to run a golfcart motor (cheap).
Then use a small onboard gas engine with alternator/generator to extend the range.

Automotive alternators put out higher voltage if you remove their voltage regulator, at that point the voltage either needs to be regulated by how fast it is spinning or by a modified voltage regulator and I'm pretty sure that there are people selling modified voltage regulators for the home built "wind turbines".

If you want to use a golf cart motor you either need the rest of the drive axle's differential to support the drive end of the motor or you need to build a new face plate for the motor and get a splined shaft to fit in to the drive end of the motor, if you or anyone else has a project that they need a splined shaft like that for, send me a message because if all goes well I'm hoping to get a price quote on having some made at a local shop that does CNC machining, I already have a hand full of them that have the other end fit in to the drive shaft of a Honda CX500 or Honda Goldwing and I have the CNC file to make them, but I don't have a price yet nor do I have solid ideas on variations that other people might want.
