Anyone know anything about electric golfcart modifications?

[gears]

So a friend picked up a MECO M-F 4 door electric "golf"cart. He wants it to go faster, I can't find any information on it. Web searches only show them at gov auctions.... Looks to be from "New Energy Electric Vehicles" as that's what's printed in English on the front of the owners manual. I haven't checked it out yet, only seen pics.

Anyone know any sites/forums that might steer me in the right direction?

Thanks in advance

3 ways: Bigger drive tires, different gearing (preferred way) more volts (shorter life, possibly immediate). Jim

I don't think there is a simple fix.
Todays golf carts are like a hybrid car that charges the battery when you are off the gas, regen mode.. So changing the voltage will not work and your charger won't work either.
The people that live in Villages in Florida use gas engines in their golf carts and they go faster.
The Villages have special roads for golf carts too.
They also have a special garage door for golf carts.

We had a 36 volt EXGO I modified by replacing the stock controller with a 450 amp unit. Stock is 90 as I recall. Upgraded the battery cables to larger ones and used a larger solinoid. It was fairly quick with a top speed in the upper 20 mph range. I never reprogrammed the controller for speed, left it set for more torque. The cart would easily spin the wheels pulling a things up into a trailer. Like a broken down mower.

Check out pit road golf carts. Here are 2 U-tube videos that I watched on how to make an electric golf cart go fast. I was looking at making a Morris Minor pickup, electric....James

That would make my beer spew when I opened it. Sheash and I thought golf was a leisurely game to relax and hunt lost balls.

I hear ya. I prefer keeping my version "Manhattan" tolerant.

Thanks guys. Rob, where'd you source the 450a controller and how were you able to figure out what your cart had initially? Jan, I think wheels are locked in by wheelwell opening on this one, gearing is in the motor/drive assembly. Geo, good reminder how "regenerative braking" is a consideration. I'm hoping that we can upgrade to full size batteries (the pics he sent look like 3/4 scale sealed units), maybe the higher output controller and wiring to support that kind of amperage. Bhole, what brand is your ride? It looks pretty slick.

Not much you can sop up an electric motor Go for changes in gearing instead

There are several golf cart websites with forums and parts. Very similar to this site. Golf Carts Unlimited and Buggies Gone Wild are two that come to mind. I think most of my parts came from the Unlimited site. AllTrax was the conyroller brand.

Quite some years ago a man posted how he used his experience and an electrical engineer to enable his otherwise stock golf cart run 46 MPH by adding some switches and rerouting wiring..
I ask him what he did to improve braking from that speed. I received that deer in the headlights look.

48V battery pack supplying a 36V motor . Jumpering resistors at the high speed position so the rotor receives a full 48V . Then adding resistance to the shunt field winding circuit to reduce the current through it at full throttle .
I had a ride on one of those , unaware of what was going to happen when the driver floored the throttle . While it did not squeal the tires nor lift the front wheels off the ground , it felt like it did . Probably the quickest 0-20Mph sprint I have ever had.
New carts with AC motors, lightweight lithium batteries and modified VFD controllers can be quick.

Yep, buggiesgonewild.com is what you seek. My "farm cart" does in the low 30's.
