Advantages of Lithium Golf Cart Batteries

Golf is one of the most relaxing sports in the world. It is a way to get away from all of the pressure and stress of daily life while working on a worthwhile hobby. Many golfers can agree that the use of a golf cart during a round is the way to go. Eliminating the strain of walking 18 holes makes golf an easier game on the body that can be played well into old age. Golf cart technology has advanced to the point where golf courses and individuals no longer have to rely on gas powered motors. Lithium powered golf carts are the way of the future. E-Z-Go golf carts now offers the Elite Lithium model that is changing the golf cart industry. Here are just a few of the many advantages of lithium powered golf carts.

Batteries that do not require maintenance

As most golf courses know, traditional golf cart batteries can require quite a bit of maintenance. However, with lithium ion golf cart batteries, you do not need to water your batteries, clean the terminal posts, and check for power holding on a regular basis. Your golf course will be able to save countless hours of maintenance work by using lithium ion golf cart batteries. Your staff will be overjoyed at the new found freedom they have to devote to other important golf issues on the course.

Your golf carts will be lighter

One of the heaviest parts of a golf cart is the clunky battery underneath the seat. On days that are wetter than most, this extra weight can cause the tires of a golf cart to dig into fairways and other areas. When switching over to lithium ion batteries, your golf carts will weigh hundreds of pounds less due to the removal of lead acid. The turf is one of your most valuable assets on your course. Having lighter carts will help you protect your fairways while giving your golfers a much more rewarding golf experience.

A battery that doesn't quit

One of the biggest detriments to a golf course is any down time. Most golfers are very busy businessmen who need to get out onto the course as quickly as possible. When your carts are down for service, this can cause hold ups that will give your course a bad reputation. Samsung SDI lithium batteries are controlled by a battery management system that ensures performance day in and day out. Efficiency, the state of charge, temperature, and the health of the battery are all easy to access. The same lithium ion technology that is being used in these golf carts has also been tested in electric cars, power tools, scooters, and other electronic devices.

Get the power you need

In mountain golf courses especially, one of the biggest complaints of golfers is the lack of power that golf carts have during hill climbs. With lithium technology, you will be able to give your golfers the power they want and need. No longer will you have carts that are struggling to get up those steeper hills on your course. This will also speed up play which will allow you to book more groups each day.

Become an eco-friendly golf course

Battery recycling can be pretty damaging to the environment. However, with lithium ion batteries, you will be able to spend less time in the recycling process and more time driving on the course. Batteries are always going to be more eco-friendly than the gas powered alternative. This zero-emissions option will be a great way to market your course as a forward thinking course that is protecting the natural environment.

EZ-GO Powerwise Charger Troubleshoot and Repair Guide

There doesn't seem to be a day that goes by at RMI Golf Carts that we don't receive phone calls or emails on the topic of battery chargers. Many times folks ask "do you guys sell chargers"?? The answer is of course "yes"! But like we tell everyone that calls, more than likely you don't need to buy a new charger. Many people are shocked to know that most of the time they can be repaired.

Once this has been established, the next question is “How do I determine if it’s bad”, and "I’m pretty handy, what parts do I need"!!

So, we’ve decided to put together a "How to" video on repairing the EZ-GO Powerwise Charger. This is the charger that works on all EZ-GO PDS 36 volt carts. It seems to be the most popular charger out, and it’s the one we see the most.

Items you will need to repair and troubleshoot your E-Z-Go Powerwise Charger

 Tools Needed

Parts You May Need

Philips head screw driver Diode Stud Type - 2010
Needle nose pliers E-Z-Go Powerwise Control Board
7/16 wrench Powerwise 50 Amp Fuse
Voltage meter with buzzer

E-Z-Go Powerwise Charger troubleshooting quick guide

Did you check the end of the Powerwise charger handle?

More often than not the issue is with the charger handle. Inside the charger handle there's a little clip. These clips wear and get pushed out of place. Pull the clip back out, so that it is grounded to the post.

Did you check the charger cord?

People have a tendency to yank the cord out when they’re done charging, this can damage it. With power supply plugged in, lift up on the cord rotate it different directions to see if the charger comes on. If the charger doesn’t come on, then you have a bad connection somewhere else.

Did you check the fuse on the Powerwise charger?

Unplug the charger. Use the voltmeter and ground it to the screw next to the fuse, and press the other end to the opposite side of the fuss. If it was a bad fuse you voltmeter wouldn’t buzz or beep. If you have a bad fuse, here is the part number for the E-Z-Go Powerwise charger: replacement 50 amp fuse part number is 2810601G01

Did you check the diodes on the charger?

Ground the heatsink board. With the other wand, touch each diode separately. If any of the diodes beep or buzz, then all of the diodes need to be replaced. The part number for the Powerwise replacement diodes is 18488G1.

Did you take a look at the motherboard of the Powerwise charger?

If the charger comes on by pressing a screwdriver to the black connector, you know it’s bad (see video for details). The replacement part number for the Powerwise charger motherboard is 28667G01.

Did you check for current continuity along the charger handle and cord?

Use your voltmeter to test the positive end of the charger handle. Press the other end to the negative line coming in (near the fuse). This is just one last check to be sure, since often the handle of the E-Z-Go Powerwise Charger is where people tend to have issues.

Troubleshooting an E-Z-Go Golf Cart

Golf Carts are now very common all around the world. They are used as multi-purpose vehicles. They were meant to commute players inside the golf course. But nowadays they are used in shopping malls, resorts, retirement communities etc. E-Z-Go electric golf cart is one among the best manufacturers of carts. But there may be issues affecting the operation of these carts. Some of the troubleshooting techniques are given below.

1. A sticky accelerator is a problem when the accelerator of the cart is in the pressed condition always. This can be checked by listening to a clicking sound. Once the engine is on and the accelerator is pressed, a clicking sound is produced. This sound is heard only when the accelerator is pressed. So if you hear the sound, when you are not pushing the accelerator, then it might be due to sticky accelerator. In such cases contact a good mechanic.

2. Do you experience low pulling torque or power while driving inclined roads? Then it might be due to loose battery connections or low power battery. Securing them tightly can solve the problem. If the battery is drained out, then its best to replace them.

3. Always make sure you maintain the tire pressure constant at the required level. A low tire pressure can reduce the mileage and increase the load on the engine. The recommended tire pressure of an E-Z-Go Golf Cart is between 18 and 22 PSI.

4. Maintenance of the battery is very essential. If properly maintained, a battery can last upto 5 or 6 years. Clean the battery terminals and casing once in a while. Also maintain an adequate level of water inside the battery cells. Use distilled water to refill, in case the water level is too low.

5. Examine all the connections to and from the battery and other electrical fittings. Any loose or faulty connection can lead to malfunctioning of the E-Z-Go Golf Cart. Make sure to tighten any loose contacts using a wrench.

Tips & Warnings

Always wear protective gloves and safety goggles before conducting any type of troubleshooting. Make sure not to over-inflate the tires. Never leave the lights and other battery powered accessories in the ON state. It can deplete the battery charge.

Gas vs Electric Powered Golf Carts

Application & Preference

When new customers come in they invariably ask, “What’s better, gas or electric?” My answer is always the same – it largely depends on how you plan to use your golf car and what your preferences are. These days, people get pretty creative with their golf carts so the intended uses can vary more than you might think. For the average user either type of golf car will make a perfectly fine recreational vehicle. Electric golf carts run nearly silently and have no fuels or oils to deal with, perfect for supporters of the green movement. Gas golf carts are a little more on the noisy side and will obviously require gas to operate - regular unleaded, to be exact.

Electric golf carts do depend on their batteries for power, so if you’re someone who wants to use your golf cart for hours upon hours at a time, you may want to stick with gas. This especially holds true for those that enjoy camping and RVing – if you don’t have access to power neither will your electric golf cart.

Another point that’s often forgotten is the amount of accessories you plan to install on your golf cart. If you want stereos, lighting, fans, heaters, etc. all of this takes a considerable amount of power. For an electric cart this energy comes right out of the same bank of batteries that your motor relies on. Gas golf cart accessories will also rely on battery power, however, they feature a starter/generator that will charge the battery on its own while the gas pedal is depressed. This doesn’t mean a gas golf cart battery is invincible - any accessories left on while the cart isn’t running will eventually kill your battery.

Performance

In the beginning, golf cars were designed to simply be what their name implies – cars for golfing. While either type of cart can easily haul you and a friend around most reasonable kinds of terrain there are other points to consider when making a decision – especially for those who expect (or demand) a little more.

With horsepower ratings ranging from 10-12 HP, gas golf cars are as much as 3-4 times more powerful than their electric counterparts. An electric golf cart, on average, will feature a 3-5 HP electric motor - but that’s not to say electric carts aren’t impressively powerful in their own right. Light hauling and yard work can be done with either type of vehicle and both will perform satisfactorily. However, those who demand power in off-road conditions with rugged terrain and steep inclines will almost always want to stick with gas power.

As we mentioned before, electric golf carts aren’t for those who wish to joy ride for hours a day. An electric cart will typically get around two hours of continuous motor run time before the batteries will need re-charging. This translates to anywhere between 18-25 miles depending on usage and the terrain – still pretty impressive. On the gas side of things manufacturers have made great strides in improving gas efficiency and the Yamaha Drive currently leads the pack in fuel economy by averaging nearly 29 MPG.

Aside from power sources and horsepower ratings, both types of vehicles operate in much the same fashion. To the untrained eye you couldn’t tell the two apart from each other and for the most part they both ride and handle the same. Both types of vehicles will get about 14-15 mph top-speed (unmodified).

Maintenance

All in all, both types of golf carts have fairly light requirements when it comes to maintenance. With electric carts your main concern lies within your batteries – make sure you check the water levels monthly (at least) and top-off as needed. The batteries are the life-blood of an electric car and with a replacement set costing well over $600 these days it’s not something you want to ignore. With proper maintenance of batteries and responsible charging habits you can expect to get 5-6 years (sometimes longer) of solid performance before they will need replacing. In comparison, neglecting your batteries can shorten their lifespan to as little as 1-2 years.

Gas golf carts, on the other hand, do require periodic oil changes as well as replacement air/fuel filters and spark plugs when necessary. For the do-it-yourselfer it’s pretty routine stuff if you don’t mind getting a little dirty. Filters are relatively inexpensive and golf cart motors take only a quart or so of 10W30 oil after every 250 hours of motor run time. The best way to stay on top of maintenance is to purchase and install an hour meter for the motor and with proper care a gas golf cart can last you a lifetime.

Summary

Now that you have a better idea of how both gas and electric golf cars operate, hopefully you’ll have an easier time making a decision. Keep in mind, this article is comparing “standard” golf carts. There are motor and controller upgrades out there to get the power of a gas golf car (and more) in electric form – though that is beyond the scope of this article.
