Don't Make These Mistakes When Buying Golf Cart Lithium Batteries

When it comes to upgrading your golf cart with a lithium battery, the choices can feel overwhelming. At Extreme Kartz, we’ve seen countless cart owners make the same costly mistakes—mistakes that could have been avoided with the right information up front.

Whether you’re tired of replacing lead-acid batteries or looking for more power and efficiency, a lithium upgrade is a smart move. But before you buy, let’s walk through the six biggest mistakes golf cart owners make when choosing lithium batteries—and how you can steer clear of them.

1. Ignoring Reputable Lithium Battery Brands

One of the most common missteps is skipping over trusted brands in favor of unknown ones. Many fly-by-night companies enter the market with cheap products that don’t stand the test of time.

While these batteries may work fine initially, the real test comes after a few years—and that’s where quality matters. The brands we’ve found to consistently deliver reliability, strong warranties, and customer support are:

• Eco Battery
  

• Epoch Battery
  

• Allied Battery
  

• Bolt Energy
  

• Trojan Lithium
  
  

Choosing one of these ensures you’re investing in proven performance rather than gambling on an untested name.

2. Falling for “Cheap Amazon” Batteries

It’s tempting to save a few bucks with a bargain lithium battery off Amazon. But here’s the catch: most of these brands lack U.S.-based customer service, which means you’ll struggle to get help if installation issues or performance problems arise.

Even more concerning, their battery management systems (BMS) aren’t designed with golf carts in mind. Many have low continuous amperage output, meaning they only work well on flat ground with light loads. If your cart has hills to climb or carries more than two passengers, you’ll likely end up replacing it sooner than expected.

3. Following Trends Instead of Your Needs

Another common pitfall is buying whatever battery is trending in a forum or Facebook group. The truth is: your cart, your modifications, and your usage are unique.

A battery that works great for someone else might leave you short on range or cause you to overspend on capacity you don’t need. Always match your battery to your specific setup and driving habits.

4. Overlooking Cart Modifications and Range Impact

Lift kits, bigger tires, upgraded controllers, and rear seat kits all increase your cart’s power demand. Unfortunately, many buyers don’t factor this into their battery choice.

Each modification eats into your range, so choosing the right amp-hour (Ah) rating is critical. The more mods you’ve added, the more battery capacity you’ll need to maintain the performance and distance you expect.

5. Buying from Call Centers Instead of Experts

Some online sellers are little more than call centers with no true expertise in golf carts or lithium batteries. They may sell you a battery, but when it comes time for installation help or troubleshooting, you’ll be on your own.

Instead, work with specialists who understand golf carts inside and out. The right partner won’t just sell you a battery—they’ll help guide you to the right choice and support you long after purchase.

6. Paying Dealer Markups

We love local dealers, but it’s no secret that many charge steep markups on lithium batteries. To make matters worse, they usually only stock one or two brands, meaning their recommendations are biased.

A smarter approach? Buy online from a trusted source to save money, then have your local dealer install it. Or, if you’re comfortable with basic tools, you can even install the battery yourself—it’s easier than most people think.

Final Thoughts

Switching to lithium batteries is one of the best upgrades you can make for your golf cart. But to get the most out of your investment, avoid these six mistakes:

✅ Stick with reputable brands
✅ Skip the cheap Amazon listings
✅ Choose based on your needs, not trends
✅ Factor in modifications when calculating range
✅ Buy from experts, not call centers
✅ Avoid inflated dealer prices

By following this advice, you’ll save money, protect your cart, and enjoy all the benefits lithium batteries have to offer.
