Higher voltage = higher speed? or not exactly

[cramermy]

hi All, I have a 2004 club car DS IQ with stock motor (AMD) stock curtis controller, and stock tires.

I converted to LIFEPO4 pack, 16s, 100 Ah. So full charge voltage is ~54.5v. I get about 14/15 mph on flat paved roads as is. I don't know if the controller was ever modified to a higher speed by a dealer or not.

My question is, should i get increased speed from the higher pack voltage than lead acid or does my controller limit the speed no matter what the pack voltage is?

thanks for the help.

The stock controller has a speed limit feature which can be adjusted up to 19 mph by a dealer or shop for about $100.
However the real benefit would be installing a 300-400, or even 500 amp Alltrax control. All of which would allow 22-23mph on stock tires... higher speeds on taller tires.

Thanks scottyb. I'm going to send you a PM about the Alltrax controller from your store.

I have had both alltrax and now Navitas. Navitas has Bluetooth so you don't need to have a usb cable wired to the controller to laptop. You just need your phone. The Navitas app also has a speedometer and ways to electronically lock the cart etc
The other thing I have noticed is that alltrax get warm to hot and need an external fan. Navitas never even gets more than warm.
