3 Must-Knows Before Buying a Golf Cart Lithium Battery

Upgrading your golf cart to a lithium battery is one of the best decisions you can make for performance, convenience, and long-term savings. But before you click “buy,” there are a few key things every golf cart owner should understand.

At Extreme Kartz, we’ve seen too many people get burned by cheap, low-quality batteries that don’t hold up over time. To help you avoid that, here are the three must-knows before buying a golf cart lithium battery.

1. The Honeymoon Phase: Why First Impressions Can Be Misleading

If you’ve heard friends raving about their new lithium battery, they’re not wrong—compared to lead-acid batteries, lithium is a huge step up.

But here’s the reality: almost all lithium batteries perform well in the first couple of years. This is what we call the “honeymoon phase.” The real test comes after that.

That’s when the differences in quality start to show. A high-quality lithium battery will maintain its performance, while a low-quality one may start failing, leaving you stranded or frustrated.

👉 The takeaway: Don’t judge a battery on its first year alone. Look at long-term quality.

2. How to Spot a High-Quality Lithium Battery

Not all lithium batteries are created equal. Here’s what you should look for:

• Metal Casing: Always choose a battery with a metal casing. It’s safer, more durable, and much better for performance. Plastic casings can be a serious safety hazard—especially if you’re running a high-performance setup.

• U.S.-Owned Brand: Batteries from U.S.-owned brands typically come with better customer support and reliability. That matters when you need service or warranty help years down the line.

• Price Point: If the deal seems too good to be true, it probably is. Cheap lithium batteries often cut corners—using a lower-quality Battery Management System (BMS), weaker components, and fewer safety features.

• Continuous Amp Discharge: This is critical. A quality golf cart battery should offer at least 120 amps of continuous discharge. For heavier carts, four-seaters, or carts with high-amp controllers, you’ll want 150 amps or more.

👉 The takeaway: Quality upfront saves you headaches later.

3. Choosing the Right Amp Hours for Your Cart

The right amp hours (Ah) depend on your golf cart setup and driving habits. Here’s a quick guide:

• 60 Ah Battery → Ideal for stock two-seaters. Provides roughly 25 miles per charge.

• 105 Ah Battery → Great for lifted carts, bigger tires, or hilly terrain. Maintains strong range even under stress.

• 105–150 Ah Battery → Best for four-seaters. If your cart has a lift kit or a high-performance controller, go with 150 Ah for peace of mind.

👉 The takeaway: Match your amp hours to your cart and how you use it.

Final Thoughts

A lithium battery is a big investment—but the right one can completely transform your golf cart experience. By understanding the honeymoon phase, knowing how to spot a high-quality battery, and choosing the right amp hours, you’ll ensure years of reliable performance.
