5: In going past the recommended voltage, does the extra voltage just overrev the motor, or do you stay within rpm range and gearup and the extra voltage/amperage will produce more power within the stock rpm range.
6: Is it worth it to use golf cart/forklift motors or just better to get the specialty motors that EV'ers use?
Golf cart motors are not going to work. Series wound DC motors rpm is proportional to voltage applied. so going from 48 to 96 in theory will double the RPM, and doing that will make the motor fly apart. The other downside to DC series motors is the torque and rpms is inversely proportional. The largest golf cart motor I know of is GE D398.
