Yamaha G29 Slow Top Speed

Hello all. I am new to the forum and relatively new to golf carts. I bought a 2014 Yamaha G29 electric golf cart to use at our place in Estero , Florida. Retirement community riding and some golf use. The batteries appear to be original Trojans. They charge fully and hold the charge for a long period of time without use ( months). At full charge, they measure about 52V ( its a 48V cart). I installed a battery meter which also shows a very slow degradation of voltage with use. My issue is that top speed is slow via hand held GPS it's only about 8mph. Seems that I should expect closer to 10-11 based on manual and other research I have done. Perhaps even a little higher. I did replace the speed sensor, but no change. pedal response seems normal in that it increases across the range of depression.

Could this still be batteries? I hate to drop a grand on batteries and not get any speed benefit. I'k=ll obviously need them at some point soon, but holding off if they still hold a charge well. Anything else I can do? Really appreciate your help IMG_0509.JPG

Test each battery individually, and see if any are horrible condition, but with 52v your pretty spot on. Maybe gps speedometer is off.
On my 2008 g29 I get about 11-12mph

I’d spend the money on something else to get speed depending how the batteries come back.

A Yamaha dealer can set the stock controller on a G29 to PTV mode with a code from Yamaha and the golf cart will run 19 MPH. I'm not sure what Yamaha charges to program the controller but I'd check with a dealer and find out. Some Yamaha dealers may tell you the golf cart needs to be street legal to get the PTV code but I know people that got their controllers programed without the cart being street legal. Like @Ac921ol mentioned you may want to test the batteries before doing anything. Welcome to Cartaholics Golf Cart Forum. :hattip:

Thanks . I contacted the local dealer and they can perform that upgrade at our condo . Not too bad - $190 for the PTV code and another $100 for the actual service call. Probably get the rear end fluid checked at that time as well. Really appreciate the help.
That is all the speed I need in the community and will be a game changer!

Did they ask you for the serial number of you golf cart? They need it so they can call Yamaha and get the PTV code for your cart from Yamaha. Let us know how it runs after they program the controller.

They indicated that they would get that when the tech was onsite. Definitely needed to obtain the code from Yamaha. Hoping for the best.
