Question on STAR EV Golf Cart
 

I am curious , can the STAR Sirius be “tuned up” to go above 20mph like you can the Yamaha Gas?

Probably, but you now own an illegal Low Speed vehicle, and if you have an accident your "golf cart insurance" may not cover you if the insurance company finds out. We leave a few minutes early in our Yamaha golf cart.
Remember golf carts are designed to go 15 MPH by the manufacturer, pushing to 20 MPH is as far as I am willing to go.

I sure new ones can be program speed up? when I rented had older star cart had high/low switch on dash which I thought was for headlights. The cart ran 21 or so till I flipped switch like I hit passing gear and quickly approached 35 plus. I let off at 35.

You either have a 110 Amp or 150 Amp battery in your Star Sirius? Or, perhaps you bought it in the Villages and the dealer turned down your speed.

Stars come from the "factory" at 19.5 mph, unless you buy the 210 Amp battery, in which case, they come tuned for about 24 mph.

The answer to your question, is yes you can tune up the speed. You likely have a Curtis Controller and all you need is the software and cable to do it ... or, find someone who has both of those.

Do you mean 110A/150A or do you mean 110Ah/150Ah?

The STAR site has a page on lithium battery specs. The pdfs for the 80Ah battery lists a max discharge rate of 120A and the rate is higher for the larger batteries. Other non-Star pages will say cruising at 15mph requires 30A-50A so a battery with even a 120A discharge capability should easily power a cart at 24mph.

Star sells both "standard" and LSV models. The spec sheet for all models lists a top speed of "19.5 mph (25mph if LSV)." The speed difference is not likely due to the battery choice but the choice of an LSV configuration. Of course, the dealer may have adjusted the speed after it was received from the factory.

It would be the 210amp version

Then I suspect your bought your Star Sirius in The Villages? I've been told (but have no personal experience) they turn the speed down on carts they sell, to 19.5 mph.

According to the Star Website and personal knowledge, the 110A & 160A come set to 19.5 MPH. I have a 210A and it came from Star, set at 24.5.

If you want more speed, your Controller has to be adjusted. I've been told that 210A Sirius carts were produced with different controllers and they don't always have a Curtis controller. You need the connector & the software for whatever controller is in your cart, to reset the speed maximum.

All I know is there are a LOT of golf carts that exceed 20 mph.

golf cart safety clinic is given on Dec 18 at Colony Cottage Rec Center. If you go to this very important class, you will hear OVER 20mph is illegal and can result in a speeding ticket of several hundred dollars. Do yourselves a favor and attend this class. You will get the correct and accurate laws involving driving a golf cart.

No one in The Villages would ever exceed the speed limit.

You can drive a car or even have a child, without going to "class", but you should take a class before you drive a golf cart. The world is upside down.

Yes
 

Yes up to 23. I bought mine 3 years ago. I was asked if I wanted to set the 23 speed. Yes. It goes 24 all day long and I still get passed all the time

The Star Sirius can be set at a much higher speed than 23 mph.

Majority do take class it called driver license.

You are exactly spot on as usual. Unfortunately many people choose to ignore the law. We have also kept ours at 20mph. I don’t understand what the hurry is with these carts going 25 or 30 mph.

Yes. I have a 2020 Star and it goes 25 mph.
