Re: Want to build a 35 MPH cart

But there can be losses. Losses dependent upon your other electrical components, tires & bearings, wind resistance, motor condition, Battery pack configuration and health, etc, like Doug mentioned already.... I just found it safer to say 25% and then let people be pleasantly surprised rather than 33.3% and have them disappointed. 25-30% is possible |

Re: Want to build a 35 MPH cart
It takes more power to go from 20 to 25 mph than it does from 15 to 20 mph! The faster the higher. And a golf cart with a full wind shield is like trying to hold up a large piece of plywood on a windy day. That is why I would cap at 35 mph.

Re: Want to build a 35 MPH cart
How much voltage can a 36v series motor take? How many watts before it melts?

Re: Want to build a 35 MPH cart
You can have it re wound by D&D or PQ. I think D&D or some has a two speed motor. I think getting to 35mph is gonna be a tough going with 48v even with all the upgrade and large tires, maybe use trailer tires for less resistance. But an upgrade to disk brakes should be on list as Scottyb said, stopping is gonna be must. Since you have not bought a new controller yet, look at one that can do 72v or even 96v buy a new solenoid and go with 6-12v batters or even 8-12v batteries. You should get your speed with that, provided you don't have to go more than 10 miles. put and on board changer and you can extend your range. Your motor, FnR, and cables can handle it. you need to up you cables to your motor to at least 2ga. Check over at the Extreme DC thread for other options.

Re: Want to build a 35 MPH cart
Good point on the brakes. Our seller said the the EZGO PDS fastest speed was limited to 19 MPH by the factory because the brakes were only rated for up to 19.5 MPH.

LSV's have a government mandated speed of 20-25mph and other than accessories are differentiated by speed alone yet they use the same brakes as golf carts. |
