Lithium Battery for Golf Cart

Are you considering changing your golf cart’s old-fashioned lead-acid battery to a self-sufficient power source? Or are you looking to upgrade your golf cart from fuel to solar? Whatever the reason is, a golf cart lithium battery is the way to go when you want your vehicle to be the least of your worries when you are hitting a few drivers.

Lithium batteries are long-lasting power storage systems that offer a considerably longer lifespan than traditional energy systems. In this article, you will find out why a lithium battery is superior than a conventional lead acid battery, its overall functioning in an electric golf cart, and its advantages compared to other golf cart power systems.

How Does a Lithium Battery Function in a Golf Cart?

An electric golf cart works just like an electric car. It is powered by a battery, in this case, a lithium iron phosphate battery, and this allows the cart to move either forward or in reverse. How golf cart’s function is relatively simple. A golf cart’s motor turns on when you step on the pedal and turns off when you stop pressing on it. The more you step on it, the faster it will go and as you let go of it, the slower it will go. This straightforward system allows for less battery use and prolongs the battery’s stored energy.

What Is the Recommended Voltage for a Golf Cart’s Lithium Battery?

Golf carts typically need a voltage of 36 or 48 volts. To get these specific voltages, you can combine a different number of batteries, which can go from 2 to 6 in total. For example, to reach 48 volts, you could use two 24-volt lithium batteries, four 12-volt lithium batteries, or six 8-volt batteries.

How Long Will a Lithium Battery Last in a Golf Cart?

Lithium batteries are deep-cycle power storage systems  that can be recharged continuously without damaging the battery’s lifespan. They last an average of 3,500 cycles of daily charge-discharge for ten years if given the proper care and kept under ideal conditions. It doesn’t mean that after 3,500 cycles it will stop working, it means that its depth of discharge (DOD) will drop to 80%, but its power won’t last as long after hitting this DOD percentage.

For example, a 48V lithium battery for golf carts will last 4,500 complete charge-discharge cycles. Once the battery has been used at its 100% DOD for 4,500 cycles, it will drop to 80% DOD and continue to give you the power you need, just at a lower DOD.

How Often Do You Need To Charge Your Golf Cart’s Lithium Battery?

Another advantage lithium batteries grant a golf cart is that they won’t get damaged if they are partially charged or discharged. So, after a long day of hitting birdies, worrying about charging it won’t be necessary. The battery will still have energy stored, depending on how much you use it, and it could still be used the next day. In case it completely runs out of power, you could charge it at another moment and it won’t damage the battery.

What Is the Price Range for a Golf Cart Lithium Battery?

The price will vary depending on the voltage, the brand of the battery, and the number of batteries your golf cart requires. For example, this 12-volt 100Ah lithium battery costs $690; if you have a 36V golf cart, you’d need to buy three of these. You could have a 48V golf cart and prefer to buy two 24-volt 50Ah lithium batteries , which cost $686 each. Doing so would be much cheaper, yet, it is vital to ensure the amps the batteries offer are adequate for your golf cart. It all depends on how cost-efficient you want to be.

How Is a Lithium Battery a Better Power Source for a Golf Cart Than a Lead-Acid Battery?

Knowing the basics of lithium batteries and their role in golf carts, we can now look into lead-acid batteries in the same role. Lead-acid batteries have been in the golf cart industry for as long as we can remember. However, lithium batteries are now the go-to choice to power golf carts. Why is that? Lithium batteries have driven their way into the golf course thanks to their numerous advantages, surpassing traditional lead acid batteries, and here is why.

Life Cycles

Lithium batteries are long-lasting, significantly more than lead-acid batteries. A lead-acid battery will last between 300 – 500 cycles, depending on the use and maintenance given. On the other hand, lithium batteries last between 2,000 to 4,000 cycles, if not more.

Protection Inside and Out

Lithium batteries with built-in battery BMS protect them from internal and external factors, such as:

  • Overcharge
  • Over-discharge
  • Overcurrent
  • Overvoltage
  • Short-circuit

Not to mention that they have an IP65 rating, meaning that when the cart is exposed to outside conditions unexpectedly, the battery will not suffer any damage. Lead-acid batteries cannot handle hot temperature climates unless they are well taken care of.

Weight and Size

Weight is a significant factor when it comes to its portability in an electric golf cart. Lithium batteries are lighter than lead-acid batteries, usually one-third of their weight. Because their components are lightweight, unlike lead, one of the densest metals, they aren’t as heavy and bulky as lead-acid batteries. You need a light, compact passenger to move around faster around the golf course, and lithium batteries are just that.

Maintenance

Lithium batteries need virtually zero maintenance, unlike lead acid batteries which need to be refilled with distilled water once or twice a month, depending on the amount of use, which means that you need to remember to do so and take the time to do it.

For lithium batteries to live a long and healthy life, the user only needs to follow the manufacturer’s basic care specifications, such as the high and low temperature precautions and storage indications. They don’t demand constant attention or physical maintenance to function correctly.

Charge Your Golf Cart’s Lithium Battery With Solar Energy

You read that correctly. Yes, you can charge your lithium battery with the simplicity of the sun’s rays. A sun-filled day doesn’t only mean a pleasant golfing day, it also means that you can power your golf cart with solar panels while at it. Forget about worrying if your battery is sufficiently charged or having to charge it after the 19th hole. Flexible solar panels  absorb the solar energy from the convenience of your cart’s roof as you are hitting some stingers. That way, after finishing, you can head back to the course the next day, assured your golf cart will be ready to go.

Advantages of a Lithium Battery In a Golf Cart

Golf carts are straightforward to maneuver. When choosing between upgrading from a traditional gas golf cart or changing their battery, the benefits a lithium battery offers outshine everything else.

The advantages lithium batteries grant are:

  • lightweight for faster driving speed
  • longer lifespan
  • BMS protection
  • faster charging speed
  • no greenhouse gas emissions
  • no expenses on fuel
  • less noise in natural spaces
  • waterproof and dust resistant
  • no constant maintenance required
  • long-lasting investment

Conclusion

If your golf cart needs a battery upgrade, a lithium battery will give it the power it needs and the distance you are looking for. Investing in a deep-cycle power system for your golf cart will undoubtedly last longer in the long run than a full tank or an out-of-date lead-acid battery.
