Golf Cart Battery Cables Exposed – Does Size Really Matter or Golf Buggy ?
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, Golf Buggy in Centurion 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.
High Speed Golf Carts: Choosing Your Options
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 Golf Buggy in JHB:
About Golf Buggy in JHB:
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.

If you have made the decision to buy used golf carts, you now have to determine if you prefer a gas-powered to an electric cart. There are benefits to both and knowing all the facts about the benefits and drawbacks will help you make an educated decision. Gas and electric used golf carts look the same, for the most part.The positive aspects of gas carts is that they have a bit more power than their electric counterparts and therefore, do better if the golf course you normally golf has a landscape with lots of hills. Gas carts tend to last longer and are quite durable; there is not a lot that can go wrong with them. Gas carts are cheaper, for the same reason gas-powered cars are cheaper than electric.If you are looking into used golf carts, chances are money is an issue, so a gas-powered may be your best option because you will get a lot better of a cart than an electric cart. However, it is wise to know exactly what your budget is and then decide which cart you truly can afford. You might be surprised and end up able to afford the electric model, unless the gas cart is truly, what you want. Regardless if, you choose gas or electric, always purchase from a reputable dealer.

Golf carts have a wide range of uses. Sure, the most obvious is for the golf course. But where else might you use a golf cart. Surprisingly almost anywhere short distances of travel are needed. Below, I'll talk about such instances where the use of a golf cart would be ideal. On the golf course, golf carts are the primary means of transportation aside from walking. Golf carts are convenient and easy to use by everyone. The use of the golf cart makes traveling across the golf course quick and painless. Typically, most golf courses use electric powered golf carts as opposed to gas powered golf carts. Several factors influence this decision, but more than likely they choose electric due to its quiet use. There are many large corporations that look to golf carts in order to help move people across large sites where businesses are located. For example, so much time can be saved by using a golf cart to travel across the worksite as opposed to walking by foot. If the need to go back and forth the workplace frequently, the amount of time saved by using the golf cart could be worth alot of money to the company compared to someone always walking. Many security companies use golf carts to patrol the grounds of a company that they are securing. The golf cart makes it easy to cover alot of ground in a little time. The quietness of the electric golf cart also is a bonus in that it may be quiet enought to catch suspecting crooks off guard. Golf carts have also been known to have a use on the home front, especially if you own alot of land. Sure, if you own a lot of land, you may have a tractor, or other large piece of machinery. Would anyone of them be as efficient as an electric golf cart? Chances are they are not, especially with the current gas prices. As noted above, there are many uses for golf carts aside from the golf course. Whether you are at the golf course, workplace, or even the homefront, the golf cart could be of use to you.
