Performance Testing of KEPWORTH 36V 150Ah LiFePO4 Lithium Golf Cart Battery
The KEPWORTH 36V 150Ah LiFePO4 battery is built to deliver consistent, high-performance power across a variety of demanding applications. We evaluated its real-world capabilities in golf cart use, hill climbing, and cold weather to see how it stands up under pressure.
Golf Cart Use: Range, Acceleration & Runtime
One of the most noticeable improvements when switching from lead-acid to this lithium battery is the immediate boost in acceleration and range. Thanks to its 200A continuous discharge capability and peak bursts up to 600A (for 3 seconds), the KEPWORTH battery provides excellent torque and acceleration, especially on electric golf carts.
In tests and customer feedback, a fully charged 36V 150Ah unit typically delivers between 30 to 45 miles of runtime on a single charge, depending on the cart’s load, terrain, and driving style. For users who previously relied on flooded lead-acid batteries, this translates to roughly 30–50% more runtime per charge and virtually no voltage sag under heavy loads.
Hill Climbing: Reliable Torque on Slopes
On hilly courses and steep terrain, the KEPWORTH battery continues to shine. Traditional lead-acid batteries often suffer from voltage drop when climbing inclines, reducing torque and stressing the motor. In contrast, the KEPWORTH LiFePO4 provides a steady voltage output, helping golf carts maintain speed and control while climbing.
This results in smoother hill performance and reduces the chance of stalls or slowdowns, making it ideal for uneven terrain, backcountry trails, or commercial golf courses with elevation changes.
Cold Weather Performance: Low-Temp Protection Built In
One of the standout features of this battery is its low-temperature cut-off protection integrated into the Smart BMS. Many lithium batteries struggle in cold climates, particularly during charging. The KEPWORTH battery addresses this by automatically preventing charging below a specific safe temperature threshold, thus avoiding permanent damage to the battery cells.
Users operating in colder regions report reliable discharge performance, although charging in freezing conditions still requires caution or external warming solutions. For best results, the battery should be used in environments above freezing or housed in a thermally controlled compartment.
Charging Time and Efficiency
Paired with a proper LiFePO4 charger, the KEPWORTH 36V 150Ah charges significantly faster than comparable lead-acid systems. A full charge can typically be achieved within 4–6 hours, depending on the charger’s output. Moreover, the charge retention is exceptional, with minimal self-discharge during inactivity.
User Experience
Users of the KEPWORTH 36V 150Ah LiFePO4 Lithium Battery have reported mostly positive experiences, especially when transitioning from lead-acid setups. Golf cart owners in particular highlight the battery’s improved torque and acceleration, with many noting that their carts feel “like new again” due to the consistent voltage delivery.
The extended runtime—frequently exceeding 35 miles per charge—has also received praise, with some users reporting an entire week of golfing on a single charge.
The Bluetooth monitoring feature adds an extra layer of convenience. Through the mobile app, users can check charge status, temperature, voltage per cell, and overall health in real time, making battery management more transparent and user-friendly.
Challenges are relatively minor but worth mentioning. A few users encountered issues with charger compatibility, particularly when using older lead-acid chargers not designed for lithium profiles. Others noted that charging in freezing temperatures required additional care despite the built-in low-temperature protection.
Comparison to Competitors
When comparing the KEPWORTH 36V 150Ah LiFePO4 battery to both traditional lead-acid and other lithium battery brands, it clearly holds its own.
Vs. Lead-Acid Batteries:
KEPWORTH’s lithium battery offers 5–10 times the lifespan of standard lead-acid units, with up to 10 years of service life. It also charges significantly faster, maintains voltage under load, and eliminates the need for regular maintenance like watering or equalization. Additionally, it’s over 50% lighter, reducing strain on vehicle components and improving efficiency.
Vs. Other LiFePO4 Brands:
Compared to brands like RoyPow, Ampere Time, and LiTime (formerly AmpereTime), KEPWORTH is competitively priced and stands out with its Smart 200A BMS and real-time Bluetooth monitoring.
- RoyPow 36V 105Ah: Slightly lower capacity and higher price, but known for industrial build quality.
- LiTime 36V 100Ah: More affordable but less power and lacks advanced Bluetooth tracking.
- Ampere Time 36V 150Ah: Similar spec but at a higher cost and with limited tech support in some regions.
KEPWORTH hits a solid middle ground in performance, price, and features.

Frequently Asked Questions About KEPWORTH 36V 150Ah LiFePO4 Lithium Golf Cart Battery
Here are detailed answers to some of the most commonly asked questions about this product:
Can the KEPWORTH 36V 150Ah battery be used in very cold temperatures?
Yes, it can be used in cold environments thanks to its built-in low-temperature cut-off protection. The smart BMS monitors the temperature and automatically prevents charging if the internal battery temperature falls below safe thresholds, typically around 0°C (32°F).
This prevents lithium plating and extends battery life. However, while it discharges well in cold temperatures, charging in freezing conditions should be avoided unless the battery is housed in a temperature-controlled environment or paired with a heater.
Is its Smart BMS compatible with other devices or battery systems?
The KEPWORTH Smart 200A BMS is internally integrated and designed to work with a wide range of golf carts, marine motors, and RV electrical systems. While it isn’t stackable in series or parallel without manufacturer approval (as some BMS configurations limit this), it communicates via Bluetooth with a dedicated app, allowing users to monitor metrics from their smartphones. Always verify if your application supports LiFePO4 voltage curves and charging profiles.
Does it provide real-time monitoring via an app?
Yes, it features a Bluetooth-enabled mobile app that gives users access to real-time information including voltage, current, temperature, charge/discharge cycles, and individual cell voltage. This is especially useful for proactive battery health management.
How long does a single charge last?
Runtime varies by application, but in golf carts, users report 30–45 miles per charge under typical conditions. Light load conditions may even stretch this range further. This makes it suitable for a full day of use or longer in most recreational and commercial setups.
Is it compatible with solar panel charging?
Yes, as long as your solar charging system is compatible with lithium batteries (specifically LiFePO4). It’s important that the solar charge controller supports the appropriate voltage and charging profile to avoid damaging the battery. MPPT solar charge controllers with lithium profiles are ideal.
Can I replace my existing lead-acid battery with this directly?
In many cases, yes. The KEPWORTH battery fits BCI Group 8D compartments and offers drop-in replacement capabilities. However, you must ensure your existing charger is compatible with LiFePO4 batteries. If not, you’ll need to upgrade your charger to avoid undercharging or overcharging.
What warranty and support are offered?
KEPWORTH provides a 5-year technical support warranty with a 10-year estimated battery lifespan. Their support team is accessible through Amazon’s “Contact Seller” feature or their official store page. Most issues are resolved within 24 hours, offering peace of mind to users.
