Golf Cart Battery Cables Exposed – Does Size Really Matter or New Golf Carts ?
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, New Golf Carts in Randburg 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.
Golf Carts: Not Just For Golfers Anymore
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 New Golf Carts in Germiston :
About New Golf Carts in Germiston :
According to new research, more than 60% of cars in the USA North America travel less than 15 miles per day and nearly half of drivers travel less than five miles away from home. With gas prices climbing higher every day and air being polluted with gas emissions, a golf car is the most environmentally friendly vehicle out there. With all the golf cart accessories available, golf carts can become the most stylish and eco-friendly vehicle on the road. Golf carts are widely used in university campuses where they transport people, goods and equipment, and are even used in cases of medical emergencies. They are also used in quiet neighborhoods, at large sports events by the personnel, and of course, on golf courses by golfers. Many golf carts are purchased by disabled people who appreciate the higher speed and safety of golf carts compared to those of power wheelchairs. Driving a golf cart is extremely economic. It costs around one cent per ten miles to operate an electric golf cart. Its also ten times cheaper to maintain and repair a golf cart than a car. However, not many automotive giants readily leap into the golf cart market, claiming that there is currently no demand for golf carts. Still, more and more neighborhoods, especially in resort areas or those surrounded by golf courses, switch to golf carts to access malls, movie theaters, schools and restaurants without having to ride on the highway. In university campuses golf carts can be used only on designated streets and paths. Golf carts, as neighborhood electric vehicles with a proper license can travel on roads with posted speed limit of 35 mph. Golf carts were introduced in the 1950s and later became popular thanks to golf visionaries such as Billy Dolan. With golf carts, golf greatly evolved as a game. Smaller, more efficient and nicely designed golf carts with cute stylish accessories such as custom wheels and seats, lift kits and even programmable speed controls, golf carts are becoming safer each year. As a vehicle, golf carts can have three or four wheels. They can be powered by electric or internal combustion motors. The most famous golf carts manufacturers include Cushman, Club Car, Daihatsu, and many more. Among the most popular golf cart accessories today are lift kits that add clearance to the golf cart which help with accessing rocky places and bumpy roads. Many lift kits include off-road tires that can be used on the golf cart making it a rough little off-road beast. Another popular golf cart accessory that is in huge demand in colder seasons is a rain curtain. These curtains can be snapped to the car frame to sit permanently on the car body, or they can be clipped to the car with hooks and removed in warmer seasons. Many golf cart accessories basically do nothing except add some flare. Racing-style aluminum pedal kits, graphic and even 3D camouflage, custom steering wheels will add a stylish touch to any golf cart. Golf carts are slowly spreading beyond student campuses, golf resorts and retirement communities. Well-designed and safe golf carts may soon be as common on city streets as scooters and bikes.

A golf cart, or golf car, is a small, motorized vehicle used to carry golfers and personnel from one place to another on golf courses. These little vehicles were designed for those individuals who cant or arent inclined to walk, such as senior citizens and the handicapped. Golf carts are typically two-seaters with room for at least two golf bags. Golf carts are now available in an array styles and colors, just like regular automobiles. The difference between regular automobiles and golf carts is that the latter, due to its small, low-powered engine, is only able to move at slow speeds, which fits it with its intended purpose: golfers can relax and enjoy the surroundings while traversing across fairways and greens during an otherwise laidback game. These specialized vehicles are built at three primary manufacturers: Yamaha, E Z Go, and Ingersoll Rand Corporation's Club Car division. The last manufacturer, known simply as Club Car, is the main source for the golf cart family. Each manufacturer has developed its own line of aftermarket parts and accessories to facilitate off-road capabilities, such as a variety of kits intended to enhance appearance and performance in non-public settings. Golf carts run on both gas-powered and electricity-powered engines, but can also accommodate larger engines, such as the Honda 24 HP v twin engine or the Briggs & Stratton engine having a variety of sizes and power capabilities that start at 16-31HP. Speed and torque gear capabilities for both gas- and electric-powered carts can also be enhanced to personal preferences, considering the particular engine is designed to accommodate such increments. Golf carts have small shallow-treaded tires intended for easy traveling on the smooth, flat or undulating surfaces of golf grass, but can be fitted with larger tires having deeper, more aggressive tread patterns for heavier terrain. Other golf cart features include: hitch mounts, cargo boxes, radios, high-performance mufflers, air filters, and paint and decal sets for that personal touch. A variety of this golf cart can also be used in many non-golf communities that are safe and quiet and have very few or no pollutants. These carts are called Neighborhood Electric Vehicle (NEVs), and have limited but incremental operating capabilities. This kind of [golf] cart is especially ideal for senior communities. Golf carts are neat little vehicles that are both convenient and easy to operate. When in nice weather and a pleasing environment, they can provide all of ones traveling needs without an effort.
Golf Cart Battery Cables Exposed - Does Size Really Matter?
While many people think that golf isnt really golf unless you walk the course, the reality is that some people just cant do that. Thats where golf carts come in handy. This author personally wont play golf very often without the benefit of a golf cart, but thats just my preference I tend to be a little lazy. But with the new golf carts that are out today, they really can make golf a little more enjoyable. Besides not having to haul your golf bag around with you, the golf cart can also help you avoid fatigue and carry along a cooler of snacks, soda, or beer along with you if thats what you like to do when you golf. You can also get a good rest on a hot day when you use a golf cart to navigate the course. There are basically three big golf cart manufacturers that dominate the golf cart market: * Yamaha * EZ Go * Club Car Some golf carts are powered with small gas engines while others are electrically powered. The electric golf carts were the first mass-produced electric vehicles for private consumer use. Modern golf carts may have car-like styling despite being no bigger than a traditional golf cart. Accessories such as audio entertainment systems, custom wheels, and custom body panels in an assortment of colors are now being offered as choices for the personal golf cart. Golf carts arent just used on the golf course. Some small communities or neighborhoods will use a golf cart where their lack of pollutants, lack of noise, and safety for pedestrians and other cars are beneficial. While purpose-built for general transportation, these are called Neighborhood Electric Vehicles and they have various operating limitations such as top speed and heavy regulation on street use. They do resemble traditional golf carts in style, but some are enclosed to accommodate for use in all types of weather. There is a huge market for aftermarket parts on golf carts. Each major manufacturing company has their own line of aftermarket parts to enhance off-road capabilities. Because golf carts can have a long life, people often buy used golf carts making these aftermarket parts very valuable to people who need to fix broken parts of their golf cart. Golf carts are considered by many golfers to be an essential part of the golf game. Others just think the golf cart make a golf course more dangerous. Either way, the truth is golf carts can really help make the game more enjoyable by leaps and bounds.
