Default Re: 48 volts with (6) 8 volt batteries

There are only 4 ways to increase speed on a correctly running series cart:

Increase rear tire diameter to 20"(assuming you have the torque to spare)
Install high-speed gearset (assuming you have the torque to spare)
Increase system voltage to the stock motor (batteries, controller, solenoid, charger)
Install a custom wound motor

There is a fifth option, but going downhill all the time is impossible.
