Summary
This is for 72 volts. These are list's of electrical components that will get you started on your way.
The first list is if you want everything electric.
{ Pictures are for viewing only they may are may not be on a 72 volt cart}
PARTS NEEDED
1. Controller that can handle 72 volts
2. Contactor's for 72 volts, both main and F/R and Bypass if used
3. Cables to handle the amps
4. Motor to handle the voltage & amps
HOW TO..
Alltrax 72 volt controller: 7245 24-72V
A big factor here is how long it will pull the amps. The 450amp is only good for 30 seconds and there is no rating from 30 seconds to 5 minutes so I can't say.
5minutes is 350amps
60 minutes is 200amps
Note these are 400amp F/R contactor: Should be good enough for most carts

I can't stress how much your cables and all the wiring must be in top shape for a high voltage cart. Everything needs to be check often and kept in very good shape. Cables should be crimped and heat shrinked at the least.
