Golf Cart Battery Cables Exposed – Does Size Really Matter or Used Golf Carts For Sale ?
For gas powered carts, the cables need only be of sufficient size to operate the starter motor, which is only for a few seconds at a time. So that answer is no, the originally installed cables are plenty sufficient in size. For those of us who have the more plentiful, battery powered carts, Used Golf Carts For Sale in Fourways the answer is somewhat more complicated. The short answer for us is, yes and no, depending upon what we expect from the cart or if modifications to the motor or controller have been made.
If the cart is absolutely bone stock (all original with no upgrades) and is used primarily as originally intended around the local course, the standard 6 AWG (aka 6 gauge or #6) cables are perfectly fine. Wire (cable) size is measured by a standard called American Wire Gauge or AWG and relates to the diameter or cross sectional area of the copper conductor itself. The smaller the AWG number, the larger the diameter, and hence, larger current carrying capacity. For example, a 2 AWG cable is larger than a 4 AWG which is larger than a 6 AWG. Most cart manufacturers use 6 AWG cables. The finest cables we have found so far are made by MaxiLink.com, which are super flexible and made for extreme duty electric vehicle use.
Ok, now for you guys that want better performance, we’ll get a little more technical. The maximum current that will ever go through your cables is when the cart is at rest and you mash the gas pedal to the floor. At that point in time, the controller puts out the max power it is capable of, and the motor experiences what is called “locked rotor” current draw, which can be hundreds of amperes. When the motor is in a stalled state, it requires tremendous energy to get it spinning to the rated RPM. If the motor were to stay in the stalled state (if there was some mechanical restraint that would not allow it to turn) the high current would continue to be absorbed by the motor until it actually burned up the windings.
Typically though, the motor begins to spin immediately, and the current drops down to 20 or so amperes within a few milliseconds (on a stock cart). There are four things that limit that maximum current; the resistance of the internal windings of the motor, the current capacity of the battery pack, the controller capacity and the resistance of the battery cables. The Battery Pack and Motor windings are pretty much fixed values. Keep these in mind because we will come back to them.
Aftermarket “high torque” or “high speed” motors installed to increase the carts performance are commonplace these days. Unfortunately, that additional performance requires additional power. The motor is only there to convert electrical energy into kinetic energy (not very efficiently either). High power motors have a lower internal resistance than stock, which in turn draws more current. If you remember from science class, power (in watts) is voltage (E) multiplied by the current (I). Since the voltage cannot go any higher than the battery’s 48volts (or 36volts), the current increases in order to satisfy the power demand of the motor. Unfortunately, this is where the resistance of the battery cables come into play. As the current increases in a conductor, power is lost in the form of heat at a rate of I2R, where R is the cable resistance.
In an ideal cable and to transfer max power, the cable resistance (R) should be zero ohms. Unfortunately all cables have some resistance. The cable resistance causes the voltage to drop (E=IR) and results in lost power to the motor. The solution; increase the size of the battery cables (the larger the cable the less the resistance). Of course, the cable diameter can only be increased within reasonable mechanical size limitations, but that is what is required to reap the full benefits of a high power aftermarket motor. Our example used the locked rotor current to explain the worst case effects. They are less drastic at partial throttle, where the current draw is significantly less.
If you want to do the drag racing, burnouts, wheelies and such with your cart though, you will need the bigger cables to supply the required massive inrush of current to the motor. Although the resistance of the cables seems tiny (#6 = 0.00047ohms/ft vs. #2 = 0.00015 ohms/ft), the voltage drop is significant when large currents are present, which will reduce performance. So for the high power motor users out there, use large diameter cables and keep them as short as possible. Size will matter to you.

Interesting Facts About Used Golf Carts For Sale in South Africa:
About Used Golf Carts For Sale in South Africa:
At one point in time, the use of a golf cart was something only the somewhat wealthy could enjoy on a golf course. Those who were not able to afford the use of a golf cart often found themselves hauling their clubs over their shoulder as they walked the golf course. Well, times have changed. Golf carts are now the standard at almost all golf courses throughout the country. Very seldom do golfers carry their clubs over their shoulder anymore. Unfortunately, some recreational golfers like to treat the course golf cart like a toy rather than a purposeful mode of transportation. Often times, you can witness wreckless behavior exchanged between recreational golfers and the use of their golf carts. However, this is one minor annoyance as a result of the golf cart gaining popularity. Typically, golf carts are available for rent from the course clubhouse. Most golfers take advantage of this service. An alternative, if you have the money, would be to buy your own golf cart. However, this is costly, but you will not need to pay rent for a golf cart whenever you go to the course. Golf carts are available for purchase either new or used. New golf carts can be purchased from anywhere from about $4000 to $11,000 dollars. Many factors attribute to the cost, such as model, seating capacity, and any additional options that may be available. There are two types of golf cart engines, gas engine or electric engine. An alternative to new golf carts would be to purchase a used golf cart. Used golf carts are alot cheaper than new ones, and typically you can find a sufficient golf cart for less than $3000. Buying a used golf cart can be alot like buying a used car. You will need to thoroughly inspect it inside and out. Make sure to ask the owner any questions you may have about the golf cart. Always make sure to take it for a test drive before committing to a purchase.

When most people think golf carts they think of a buggy that takes a golfer and his golf clubs around the course. And thats a fair assumption seeing that is what they were originally produced for. But in this day and age there are other uses apart from the obvious. Many large companies with many warehouses or factories also find a need for golf carts. Traveling to and fro between buildings is made easier and faster when using a golf buggy. These little buggies are not only convenient but also can be very useful along with the fact that they can be affordable. You will find many manufacturers that produce these golf carts in either a manual push and pull, electric or gas version. Some can carry passengers as well as a golf bag.And for the people who like to be a little different there are companies that make custom versions to satisfy that individual need. You dont have to have a custom version to be a little different as you can just add some ATV wheels to make yours stand out from the others if that is what you wish. If you are a fanatic golfer or just an occasional golfer then golf carts are still a great way to get around that 9 or 18 hole course. Of course you can purchase your own or you have the option of hiring one as well. Many courses have them for hire for reasonable prices but there may not always be one available.

Golf Carts Not Just For The Golf Course Anymore
To find a Harley Davidson Golf cart in pristine condition is truly a find. You will find Harley Davidson Golf Cart collectors all over the United States. The Harley Davidson company started building golf carts in 1963. They started out building both gas golf vehicles as well as electric cars.
The first Harley golf cars where three wheeled. The cart had 2 rear wheels and one center wheel in the front. The cart had a unique steering bar that was used instead of a steering wheel. This steering handle is actually called a tiller steering wheel. The three wheeled carts are less stable on hard turns than their four -wheeled cousins but the unique look of the cart make collectors salivate when they see a nice one. The electric carts were actually less popular and thus there are fewer of these carts in existence today.
The rear end on some of the carts were raised to give the cart a deep well. This well is where the golf club bags were placed. This particular model is known as the "Classic". These models also had only three wheels. Although the back was raised, this should not be confused with the lifted golf carts you sometimes see today.
The attraction for HD carts started to fade and production stopped ultimately in 1982. Since then, several companies have produced cheap quality Harley-Davidson golf cart replicas. For those wanting a an original, it is highly advisable to look into having an expert in golf cars look at the cart first.
Today people drive these street legal carts around golf courses and retirement villages. Owners are a still buying golf cart accessories for Harley Davidson Carts as many of these carts are still actively used. The restoration of these carts are not only fun but rewarding. There really is not a lot to a golf cart and the restoration of a HD car is not only fun but a fairly easy project. It is certainly much easier than trying to restore an automobile.
