What kind of speed should I expect?

Jdulac88 · 10-12-2016, 11:35 AM

So now that I think I identified my controller on my cart. I was wondering what kind of speed (MPH) I should be getting out of my 36V-DS with a 480AMP controller and a GE D379 motor on stock tires. I tested it this weekend and could only reach 12MPH on flat run. I am wondering if I have a bottleneck somewhere or if this what I should be getting. Seems I should be getting a bit more out of this setup but I am new to the whole cart thing.

Do you know how many HP that motor has? 12 mph may be about right, especially for a series cart. I would think that your setup would have a lot of torque (hill climbing power). Does it?

The 480 controls were series.

Here Google is your friend. 12MPH is a bit low.

Thanks jjance, I was too lazy to do that...

I agree, 12 does seem low based on those specs.

Carts set up for golf use run about that speed.

For my job I am in charge of fleet carts at a golf course and they usually run around 15 MPH stock with good batteries from the factory, so that does seem low.

No not really it bogs down on slight hills at my camp ground. That's why I am wondering where my issue exist. I still have not found any numbers on my controller. But considering it looks to be a kit I would have a hard time believing they would have put a lower rated controller. Another issue is my batteries look to be shot as they are bulging and don't hold a charge for very long. Even though after charge I get good readings on my volt meter. I'm really considering going to 48V since I need new batteries any way. But fi I do that what kind of charger will I need. And than there's the f/r switch and selenoid. I'm hoping to get pictures of everything on here so you guys can lead in the right directions. I would like to get this thing cruising. And by cruising I would be happy with 17-19mph.

Anyway here are the complete specs I have found on the motor.

It is rated at 4hp @ 4150 rpms on 36 volts. It is also rated at 5.5hp @ 5700 rpms on 48 volts. It is designed to run either 36 or 48 volts. And says speeds up to 15-16MPH-36V and 19MPH-48V with 400AMP Controller.

what kind of controller do you have? a stock"480" controller. if i'm not mistaken this is a 200 amp controller. If that is the case you are right were you should be. you can go up to something like a 36v 400 amp, but your limited to your motor output. so yea going to a 48v 400 amp gives you an extra 1.5 hp but alot of replacement parts. At that point i would look into a newer cart, EZ-GO PDS carts come stock at 350 amp, can do a lot just with a programmer, and freedom plug, IMHO

My cart is far from stock its an 88. It was originally a coil system no controller. Any way I believe that my controller is an older Curtis 480amp.

I don't think I'm very from conversion to 48v. But would love to hear opinions.
