Golf carts have outgrown their reputation as quiet runabouts for golf courses. Today, they’re just as likely to be found in residential estates, warehouses, schools, and caravan parks as they are on the green. Whether you're operating a single cart or managing a fleet, one thing remains constant: battery performance is central to the cart’s reliability and runtime.
Choosing between AGM and lithium batteries can feel like comparing apples and oranges. The two technologies behave differently under load, recharge at different speeds, and offer very different life cycles. This guide will walk you through the real-world pros and cons of each option, help you understand battery sizing, and explain compatibility concerns specific to Australian golf cart users.
Why Battery Choice Matters More Than You Think
The battery is the powertrain of your electric golf cart. Poor quality or mismatched batteries can limit your cart’s range, reduce acceleration, and wear out faster than expected. On the other hand, the right battery setup can deliver smooth operation, minimal maintenance, and cost savings over time.
Modern battery upgrades are not just about picking the biggest capacity. They need to match the cart’s voltage system, fit in the tray, and support your driving habits. For users who rely on carts daily or across variable terrain, that choice becomes even more important.
AGM Golf Cart Batteries: A Proven Upgrade from Flooded Lead-Acid
AGM (Absorbent Glass Mat) batteries use a sealed lead-acid design that traps the electrolyte in a glass mat between the plates. This structure eliminates the risk of acid spills and makes the battery maintenance-free. It is a step up from old-school flooded batteries, particularly for users who want a reliable replacement without overhauling their existing system.
At DC Direct, we offer AGM batteries from brands like Power-Sonic and Forge that are specifically built for deep cycle applications. These units deliver stable voltage output under load and handle repeated charging and discharging with ease.
When AGM Is a Practical Choice
- You are replacing batteries in a 36V or 48V system and want a plug-in fit
- Your cart is used occasionally or across flat terrain
- You prefer a sealed, zero-maintenance option over wet-cell lead-acid
-
Your charger is not lithium-compatible and you want to avoid upgrading it
Performance Snapshot
- Cycle life: 500 to 1000 cycles depending on depth of discharge
- Charge time: 6 to 10 hours
- Weight: Approx. 30kg per 12V unit
-
Discharge depth: Usable capacity sits around 50 to 60 percent
AGM batteries are well-suited to golf clubs, retirement villages, and other environments where carts are driven lightly and charged overnight.
Lithium Golf Cart Batteries: For High-Use and High-Performance Applications
Lithium iron phosphate (LiFePO₄) batteries offer a completely different experience. These batteries are lighter, recharge faster, and deliver significantly more charge cycles. While the initial investment is higher, they outperform AGM across almost every metric.
At DC Direct, we supply lithium golf cart batteries from Invicta and Forge that feature integrated Battery Management Systems (BMS). These batteries regulate charging, protect against thermal issues, and monitor individual cell health.
When Lithium Makes More Sense
- Your cart is in regular use or operates in commercial conditions
- You run auxiliary gear like spotlights or radios from your battery
- You need faster charging between shifts or during solar hours
-
You want the lowest lifetime battery cost, not just the lowest upfront
Performance Snapshot
- Cycle life: 2000 to 5000 cycles with proper care
- Charge time: 2 to 4 hours with a lithium-compatible charger
- Weight: Up to 60 percent lighter than equivalent AGM
-
Discharge depth: Up to 100 percent usable capacity
Lithium batteries suit property owners, high-use commercial carts, and long-range resort vehicles where reliability, runtime, and rapid recharge are critical.
Real-World Comparison: AGM vs Lithium
Weight
AGM batteries are heavy. A 100Ah 12V unit can weigh more than 30kg. Lithium equivalents can weigh 12kg to 15kg. In carts where tray weight affects performance, lithium has the clear advantage.
Lifespan
AGM batteries offer around 500 to 1000 cycles. Lithium batteries, by comparison, regularly exceed 2000 cycles. That can mean 7 to 10 years of life in moderate conditions.
Charging Time
AGM batteries typically take 6 to 10 hours to fully recharge. Lithium models can reach full charge in less than half that time with a compatible charger.
Discharge Profile
Lithium maintains a stable voltage even when the battery is nearly empty. AGM voltage drops more noticeably with each discharge cycle, reducing performance under load.
Maintenance
Both are sealed and maintenance-free, but AGM still requires careful attention to charge depth and cycle limits to avoid early degradation.
System Compatibility: 36V and 48V Golf Carts
Golf carts generally run on either 36V or 48V electrical systems. This is made up of multiple batteries wired in series.
36V setups often use:
- 6 x 6V batteries
-
3 x 12V batteries
48V setups often use:
- 6 x 8V batteries
-
4 x 12V batteries
You can rebuild these systems using either AGM or lithium batteries. When converting to lithium, always check that your voltage matches the controller and that the onboard charger is either programmable or compatible with lithium charging profiles.

Sizing and Installation Tips
Before you purchase, take a few minutes to confirm the following:
1. Tray Dimensions
Lithium batteries are often smaller than AGM, so you may need trays or brackets to secure them correctly.
2. Terminal Orientation
Check if your cart uses front-facing or top-mount terminals. If space is tight, battery terminal orientation can save you costly rework.
3. Battery Monitoring
Many Invicta lithium batteries include Bluetooth monitoring, allowing you to check battery status and charge via a smartphone app.
4. Charging Compatibility
Do not use a lead-acid charger with lithium unless the charger has selectable modes. Visit our battery charger collection for compatible options.
5. Fuse and Cabling Accessories
Upgrading your battery may also require new fuses, shunt monitors or heavy-gauge cables. Find what you need in our accessories collection.
AGM vs Lithium: Which Is Best for You?
Choose AGM if:
- You want a direct replacement for existing lead-acid batteries
- You use your cart casually and can charge it overnight
-
You want a reliable but cost-effective solution without new components
Choose Lithium if:
- You operate your cart every day or in a commercial setting
- You need long runtimes and fast recharging
- You want to reduce cart weight and extend total battery life
-
You have solar charging or remote usage where power access is limited
If you’re still unsure, the team at DC Direct can guide you through the best fit based on your specific cart model and usage patterns.
Frequently Asked Questions
What type of battery is best for a golf cart: AGM or lithium?
Lithium is better for high-use, long-range carts and offers longer lifespan and quicker charging. AGM is a good fit for budget-conscious users replacing existing lead-acid banks.
Can I switch from AGM to lithium in my golf cart?
Yes, provided the voltage is matched and the charger is compatible. Most Invicta lithium batteries come with integrated BMS for safe drop-in installation.
How long do lithium golf cart batteries last?
You can expect 7 to 10 years of performance depending on charging and depth of discharge. This is two to three times longer than AGM in most use cases.
