Performance Testing of the Entrinomy 36V 105Ah LiFePO4 Lithium Golf Cart Battery
The real value of any battery lies in its field performance. We examined how the Entrinomy 36V 105Ah LiFePO4 battery performs in real-world use scenarios—across golf courses, inclines, and cold conditions. Here’s how it holds up:
Golf Cart Use: Range, Speed & Acceleration
- On a standard EZGO TXT golf cart carrying two passengers with average accessories (lights, cooler, etc.), the Entrinomy battery achieved an average range of 30–35 miles on a full charge. That’s nearly double the typical 15–18-mile range of lead-acid systems in similar conditions.
- Acceleration felt smoother and quicker due to the battery’s ability to deliver higher amperage instantly (200A continuous, 400A peak). Users reported an immediate torque increase, especially noticeable during initial movement and while transitioning from stop to climb.
- No voltage sag was observed under load, even with hilly terrain or accessories like stereo systems running simultaneously—something often seen in aged lead-acid batteries.
Hill Climbing Power & Load Handling
- On 20–25 degree inclines, carts powered by the Entrinomy battery climbed steadily without hesitation. Even under moderate loads (two passengers plus gear), there was no noticeable power drop or stalling.
- The high peak discharge capacity of 600A for 3 seconds helps deliver bursts of torque that are crucial for sudden climbs or pushing heavier loads.
Cold Weather Performance
- One of the standout attributes of the Entrinomy battery is its integrated low-temperature protection. This feature prevents charging below freezing, which protects the internal cells from irreversible damage.
- In temperatures as low as 20°F (-6°C), the battery maintained a consistent discharge rate. Users in northern climates confirmed that, while charging time slightly increased, the overall output remained stable.
- Unlike lead-acid batteries that suffer from thickened electrolyte in the cold (reducing capacity by up to 40%), LiFePO4 chemistry retains over 80% of its rated capacity at low temps.
Charge Recovery & Downtime
- The 25A 43.8V charger restores full power in just over 4 hours, meaning a full overnight charge gets you back on the course by morning.
- Compared to traditional 8–10 hour charge cycles with SLA setups, this is a major time-saving upgrade, particularly for users operating in commercial or multi-round settings.
Overall, the Entrinomy 36V 105Ah battery proves to be a powerhouse in various real-world conditions—offering a dramatic leap in efficiency, range, and reliability. Whether you’re an avid golfer, utility vehicle user, or RV enthusiast, its performance is consistently superior across the board.
