72 volt ezgo

[rhgc]

Has anyone ever done an ezgo 72 volt conversion? I know it would involve a lot of heavy duty upgrades like FandR, motor, complete wire job, controler. I was wondering if anyone had any experience in such a big conversion? If so can ya give me a few ideas where to get the parts?

Welcome to the forum...

What year is your cart?
You would need a 72 volt controller, Alltrax would be my recommendation.
All cables changed to 2 ga.
HD buss bars in the forward and reverse switch.
72 volt solenoid.
Batteries and a charger, I would use six 12 volt deep cycle batteries.
The stock motor will work with 72 volts but you could always use a after market motor also.
Their's a few carts I know of running 72 volts. One of them is Andy's "Mud Buggie" I'm sure he can offer you advice on the upgrade when he sees this thread.

Meltravis is running 72 in an old marketeer. I don't think he changed anything, coil etc. He may be running 48 with 24 on stand by.

it will be a 2005 ezgo. the only motors I know of are for 36 or 48 volt. 72 volts wont burn it up?

To a point its not voltage that kills the motor it's the RPM. The stock EZGO series motor is rated for a max of 8000 RPM. I wouldn't run one at 8000 RPM to long but that's what they're rated at. A stock cart only runs at approx 2800 RPM so their's a lot of room to up the voltage. I've seen quite a few carts running 72+ volts with the stock 36 volt motor.
If you do go with a aftermarket motor I'd suggest a D&D

72 volts in a 1990 Ezgo now for 3 years. You will need a motor to handle the amps & voltage.
