Over the past few months, I’ve been upgrading and testing lithium batteries in a couple of different golf carts some used for neighbourhood rides, others for rougher terrain. What I’ve learned? The battery you choose can completely transform how your cart performs.
Traditional lead-acid batteries just don’t cut it anymore. They’re heavy, slow to charge and wear out way too fast. Switching to LiFePO4 (Lithium Iron Phosphate) batteries has been a game-changer for me. They’re lighter, last longer, charge quicker, and deliver smooth, reliable power whether you’re cruising flat paths or climbing hills.
I’ve tested these five batteries in real-world conditions, everything from short daily drives to full-day trips with passengers. Below are my top picks based on performance, ease of use, safety features, and value.

5 best 48-volt lithium iron batteries for golf cart
Golf carts need strong, reliable batteries to perform their best especially on hills or longer rides. Lithium iron phosphate (LiFePO4) batteries are a massive upgrade from traditional lead-acid ones. They’re lighter, charge faster, and last way longer. Below are five standout options we’ve tested and loved for everything from everyday cruising to all-day adventures.
1. Weize 48V 100Ah TM LiFePO4 Lithium Battery
What I Like
Very versatile can connect in series to make 24V, 36V, or 48V systems Lightweight and compact compared to lead-acid Long cycle life (up to 2000+ cycles) Built-in Battery Management System (BMS) for safety
What I Don’t Like
Needs multiple units for golf cart use (it’s a 12V battery) Doesn’t come with a charger or mounting hardware
I started using the Weize 12V 100Ah LiFePO4 battery when upgrading a custom golf cart system, and it’s been impressively reliable. Though it’s a 12V battery, it can easily be connected in series with others to match your cart’s voltage—whether that’s 24V, 36V, or 48V. That makes it super flexible for all setups, from golf carts to solar or RV systems.
What stands out is how lightweight it is compared to the old-school batteries. It doesn’t sag your cart down, and charging is way faster, too. Plus, the built-in BMS means you don’t have to stress over overcharging or overheating it’s got your back.
If you’re building a custom battery bank or looking for a modular option with solid performance, the Weize 12V 100Ah is a great place to start.
Voltage: 12.8V | Capacity: 100Ah | Cycle Life: 2000+ cycles | Use Case: Modular, multi-purpose | BMS: Yes

Genuine 48V battery drop-in ready for most golf carts Huge capacity, perfect for long rides or hilly areas Built-in smart BMS for added protection Faster charging and longer lifespan than lead-acid
What I Don’t Like
A bit heavy compared to smaller capacity options Higher upfront price (but pays off long term)
This 48V (51.2V) 100Ah LiFePO4 battery is a beast—in the best way possible. It’s a plug-and-play upgrade for most golf carts and gives you seriously improved performance. I noticed smoother acceleration, longer drive time, and much less charging hassle within just a few uses.
What I appreciate is the peace of mind the smart BMS provides. It manages everything behind the scenes—temperature, voltage, current—so the battery stays protected no matter how hard you drive it. Whether you use your cart for golfing, campus cruising, or daily commutes around the neighbourhood, this battery delivers the consistent power you need.
It’s built to last for years, with up to 3000 cycles. That’s several times more than any lead-acid battery I’ve used before. If you’re ready for a serious upgrade and want zero compromise on performance or durability, this one’s a no-brainer.
Voltage: 51.2V | Capacity: 100Ah | Cycle Life: 3000+ cycles | Use Case: High-power golf carts | BMS: Smart built-in
3. LiTime 48V 60Ah Lithium Golf Cart Battery with Charger
What I Like
Comes with a dedicated charger—no guesswork needed Compact and lighter than many 48V options Solid build quality and reliable BMS protection Great for moderate daily use and shorter trips
What I Don’t Like
Slightly lower capacity than others in the same category Not ideal for steep hills or heavy-duty carts
The LiTime 48V 60Ah battery is a solid choice if you don’t need a super high-capacity battery but still want a quality lithium upgrade. What’s especially handy is that it comes with its own charger, perfectly tuned for the battery. That takes the hassle out of figuring out compatibility—just plug and go.
This battery holds up really well for flat to moderate terrain or daily campus-style driving. It’s lighter than some of the higher-capacity models, which helps with speed and cart agility. I also appreciate the BMS doing its job quietly in the background—no overheating, no weird voltage drops.
If you’re switching to lithium and want something affordable, compact, and easy to install, this is a fantastic middle-ground option.
Voltage: 48V | Capacity: 60Ah | Cycle Life: 3000+ cycles | Use Case: Moderate daily use | BMS: Yes | Includes Charger: Yes
