Innovative Lithium Golf Cart Battery Solutions from Enertec

When it comes to running a resort golf cart fleet, managing a luxury golf estate, or maintaining a busy golf cart servicing workshop, your electric golf carts and trolleys are only as reliable as the batteries that power them.

In a sector where uptime, guest satisfaction, and operational efficiency are non-negotiable, battery technology is no longer a background detail; it’s the heart of the entire operation.

That’s why Enertec has introduced its GC2 and BLOCK series lithium batteries, a premium LiFePO₄ solution purpose-built for golf carts and electric trolleys. GC2 batteries are available in 24V 60Ah, 36V 45Ah, and 48V 30Ah configurations, whereas the Block Series is available in the 38V 105Ah (36V system) and 51V 105Ah (48V system) these batteries deliver the perfect balance of lightweight design, rapid charging, intelligent management, and extreme durability.

In this guide, we’ll explore why lithium is the future of golf cart power, how the GC2 and Block series compare to traditional batteries, and why Enertec’s nationwide expertise makes them the supplier of choice for South African businesses.

Why Lithium Power is a Game-Changer for Golf Carts

Traditional lead-acid batteries have powered golf carts for decades, but they come with drawbacks — heavy weight, regular maintenance, long charge times, and a limited lifespan. Lithium Iron Phosphate (LiFePO₄) batteries like Enertec’s GC2 and Block range overcome these limitations by offering:

High energy density for a longer range per charge.
Consistent voltage output — carts maintain full performance until the battery is almost empty, resulting in longer run times than lead-acid batteries.
Quick recharge — Allows golf carts to be put back into service much quicker than those using lead-acid batteries.
Significantly lighter weight, improving handling and efficiency.
No maintenance — no watering, no acid spills, no corrosion.
Long cycle life — 2,000+ cycles at 80% depth of discharge, compared to 300–800 for lead-acid.

The result?

Lower total cost of ownership (less batteries required over the total lifespan)
Lower lifetime costs, better reliability, and happier drivers.

Introducing the Enertec GC2 and Block Lithium Series

Enertec’s GC2 and Block range is engineered for professional golf cart and trolley applications, from high-end resort fleets to private golf estates and service/maintenance vehicles. All five models share the same core advantages:

24V 60Ah: Ideal for smaller fleets and electric trolleys.
36V 45Ah: Suited to mid-range golf carts and multi-passenger buggies.
48V 30Ah: Perfect for high-performance carts and premium applications.
38V 105Ah (36V system): Suited to mid-range golf carts and multi-passenger buggies.
51V 105Ah (48V system): Perfect for high-performance carts and premium applications.

Shared features include:

Bluetooth App Connectivity: Monitor real-time voltage, state of charge, and health from your phone.
LED Status Indicators: Quick visual check of battery readiness.
Integrated Battery Management System (BMS): Balances cells, prevents overcharging, and protects against deep discharge.
Lightweight Design:
- GC2: Around 12–13 kg, making them easy to handle and install.
- Block: 35- 45kg, there is only one battery required.
Rugged Construction: Built to withstand vibration, shocks.
Maintenance-Free Operation: No watering or acid checks.

GC2 & Block Lithium vs. Traditional Golf Cart Batteries — The Numbers

Feature	Enertec GC2 Lithium (24 Volt / 36 Volt / 48 Volt)	Enertec Block Lithium (38 Volt / 51 Volt )	Standard Lead-Acid Golf Cart Battery
Cycle Life	2,000+ cycles @ 80% DOD	< 3000 cycles @ 80% DOD	300–800 cycles @ 50% DOD
Weight	12–13 kg	35 - 45 kg	28–32 kg (per battery)
Maintenance	None	None	Regular watering, corrosion checks
Charge Time	2–6 hours	2-6 hours	6–12 hours
Performance	Consistent voltage until empty	Consistent voltage until empty	Gradual power drop during use
Energy Efficiency	95%	95%	70–85%
Service Life	6–10 years	8-12 years	2–4 years

The difference is more than just convenience — it’s about keeping fleets operational, reducing replacement cycles, and cutting labour costs. Once again, lower total cost of ownership

Key Benefits for Resorts, Estates, and Fleet Operators

Extended Operational Hours
Lithium’s fast charging and long runtime mean carts spend more time moving guests, staff, and equipment, and less time on the charger.
Improved Guest Experience
Consistent power delivery means no sluggish uphill climbs, no dim lights at dusk, and no unexpected stops mid-route.
Lower Lifetime Costs
While the upfront investment is higher, GC2 and Block lithium batteries last 3–5 times longer than lead-acid batteries and require no maintenance.
Easier Fleet Management
Bluetooth monitoring lets you track battery health across the fleet, identify underperforming units, and plan replacements proactively.

How to Choose the Right GC2 Model

When upgrading or specifying a golf cart battery, match the voltage and capacity to your cart’s requirements:

24V 60Ah: Ideal for light-duty carts, trolleys, and short-range applications.
36V 45Ah: Balanced choice for most standard 2–4 seat carts.
48V 30Ah: Designed for top-tier carts with maximum performance needs.
38V 105Ah (36V system): Balanced choice for most standard 2–4 seat carts.
51V 105Ah (48V system): Designed for top-tier carts with maximum performance needs. Please hyperlink to website

Consider:

The number of batteries used in parallel (GC2 models) must be directly proportional to the operational usage of the vehicle. EG: More rounds of golf per week require more batteries in parallel.
A minimum of two batteries in parallel is mandatory (36V / 48V) (GC2 models)
Regular and prolonged service requires more batteries in parallel (GC2 models) - consult your Enertec agent.
The manufacturer’s recommended voltage and Ah rating.
Terrain and load (hilly courses and passenger-heavy carts benefit from higher voltage).
Charging infrastructure (ensure compatibility with lithium chargers).

Upgrading from Lead-Acid to Lithium

Transitioning to GC2 and Block lithium batteries can transform fleet performance, but it’s important to:

Check charger compatibility: Lithium batteries require lithium algorithm programmed chargers.
Verify physical fit: GC2 and Block lithium batteries are more compact and lighter, but terminal positioning should match.
Training: Train staff on charging protocols and Bluetooth monitoring.
Parallel: The number of batteries in parallel for the GC2 models must be proportionate to the operational requirement. (more load = more batteries)

Signs It’s Time to Upgrade

If your current fleet uses lead-acid batteries, watch for:

Frequent battery replacements (every 2–3 years).
Carts are slowing down before the end of the day.
Increased maintenance time (watering, cleaning, corrosion).
Guest complaints about performance.
Rising electricity costs from long charging times.

Best Practices for Lithium Battery Care

While GC2 and Block lithium batteries are low-maintenance, a few simple steps will maximise their life:

Use a compatible lithium charger with the correct lithium algorithm.
Keep batteries charged between uses — avoid letting them sit fully discharged.
Store in a cool, dry place when not in service.
Check the Bluetooth app periodically for any abnormal readings.
Ensure the correct number of batteries are connected in parallel
