Since you all have so much knowledge about golf carts, tell me, is there a governor on electrics? Our cart takes off so fast it will nearly through you off the back seat (we got seat belts for the kids anyway, but my wife swears it will) but once you reach a certain speed, it just won't go faster...even with a full charge. I was wondering if they come from the factory with some kind of limiter switch or something to keep the speed down on golf courses that could be removed or switched off so that it would go faster. Or is this something that would require a new motor and more batteries?
The electric cart has many factors that determine speed. As far as I know, there is no governor. We used to fly down the hills at our golf course, but couldn't do it with the gas.
Anyway, back to your questions.
Speed is determined by a variety of things. 1. Motor 2. Batteries 3. Tires
The more your batteries are charged, the faster your cart will go. However, brand new batteries will make your cart go faster, but at a certain point it maxes out. Most carts are either 36 or 48 volt carts. I heard Tung mention a 72volt cart, but I've never seen one.
The motor hp is the main variable in cart speed. Most carts have a 3.5 hp motor I believe (Tung Po can verify). You can upgrade to a 5.5 hp motor and see an increase in speed. I am thinking of going to 11hp.
If your cart is lifted, with the bigger tires, that will also increase the speed. The problem is, the 4 tires will run you close to $500 for the wheels and rims (although I think they look cooler)
The other "variable" is the controller. I have an Alltrax 500 amp. It is programmable. You can have it set for maximum torque to shoot off the line, ( I don't, with kids it's not worth it). However, the main advantage to me is that the fact I can pass others, it gives lateral movemnent pickup. The disadvantage to the high amp controller, is you need to upgrade the wires on the cart that connect all the batteries.
Hope this helps, and doesn't confuse more...... Tung may have some more insight
