Default 2015 ezgo txt only 8mph?

Hey everyone, I'm new to the cart world and just got my first one. Its a 2015 ezgo txt 48v. The problem I have is that the cart has NO top end speed. The cart gets to about 8mph pretty quickly, but that's it. It goes about the same speed in reverse. My batteries are original, but seem to be in good condition. Any insight on why there is no top end speed? Thanks
Wes

The batteries are always a good place to start for any power issue. Let the charger run until it shuts off on its own, then wait 10-12 hours and get a reading of the pack voltage. Then leave your mm hooked up to the pack and go drive up a good hill. Record and post the readings of the pack at rest and under a good load.

sounds like a speed sensor wiring or unit problem - cart should go 14 mph if it goes at all.

It seems fine on hills. Not really any issues anywhere other than it hits 8mph early and just tops out. It doesn't seem to slow down, just tops out quickly.

I would bet the speed code is set to that. Did you buy it from a dealer or individual? If it is the speed code you can get it to 14.5 with just a setting. Faster requires a programmer and a dongle or a higher end programmer. Where are you located ?

Bought it from a private seller. Located in NE ohio. Is that something that can be done DIY or only through a dealer?

Getting to 14.5 you just need access to a handheld programmer. Higher that that you need either a freedom dongle(dealer) with handheld or someone with a modified programmer to get you to 19.5

Thanks, I appreciate it. I will double check all batteries and connections tonight and then if those are good, I will look into getting my hands on a programmer.
