Enjoy more power in a smaller package, seamless operation, and the reliability you can trust. KeepKnow MINI 48V Intelligent Power System delivers efficient performance, fast charging, and lasting durability.
Ultra-Compact Steel Powerhouse (51.2V 105Ah): Maximum power in minimum space. Delivers 5.376kWh of energy in a surprisingly compact SPCC steel casing (13.8×12.4×9.2 in). Perfect for tight battery trays where standard batteries won't fit, without sacrificing capacity.
Industrial Relay-Based BMS (250A): Built for heavy duty. Uses a robust Mechanical Relay (Contactor) instead of standard MOSFETs. This ensures superior resistance to high current impact, delivering 250A continuous and 500A surge (30s) for powerful acceleration and hill climbing.
Compliance certified & Rugged Safety: Certified to the highest safety standards (CE, FCC, UN38.3). The heavy-duty metal housing is vibration-resistant, provides excellent heat dissipation, and features IP65 protection for stable performance in tough and uneven conditions.
Advanced Dual-Balancing Technology: Maximize battery life. Features a unique dual-mode balancing system (Charge Balancing + Static Balancing). This keeps internal cells perfectly aligned for optimal efficiency and longevity.
Smart Control (Touchscreen + Bluetooth): Total command at your fingertips. Includes a dashboard LCD Touchscreen and Bluetooth App. Monitor SOC, Voltage, and Temp in real-time, or trigger "Emergency Shutdown" remotely for ultimate safety.
All-Weather Charging Bundle: Includes a matched 58.4V 22A LiFePO4 charger. The system features intelligent Low-Temp Cut-Off (stops charging <32°F/0°C) and High-Temp protection, ensuring safe operation from -4°F to 149°F.
Universal Golf Cart Fit: Designed for seamless integration. Compatible with 48V Club Car, EZGO, Yamaha, and other major brands. The compact footprint makes installation easier in modified or space-limited carts.
Exceptional KeepKnow Service: Experience premium support. Backed by a 5-Year Warranty, lifetime technical support, fast delivery, and responsive 24/7 customer service.

Premium Grade A LiFePO₄ cells provide stable power, excellent durability and extended service life. The intelligent 250A BMS offers comprehensive protection to ensure safe consistent and reliable performance.

Designed with a smaller footprint than traditional lead acid batteries this lithium battery measures only 15.3 × 12.4 × 10 in while weighing 98.3 lb. Its compact design saves valuable space and M8 terminals provide secure connections for easy installation.

It maintains steady operation under frigid conditions. The battery supports charging at temperatures above 14°F (-10°C) and discharging down to -4°F (-20°C), supplying consistent and trustworthy power for golf carts in cold weather applications.

You can monitor battery status conveniently through two user-friendly solutions: view real-time battery data directly on the built-in touchscreen, or remotely track key parameters such as SOC, voltage and temperature via the KeepKnow APP.

Equipped with a power switch communication port and pressure relief vent for enhanced safety reliable operation and easy battery status monitoring.

It achieves a maximum driving range of 76 miles for stress-free daily use. Excellent peak discharge capability supplies steady power, enabling easy navigation on uphill slopes and muddy road conditions.

This LiFePO4 battery is a premium retrofit alternative to classic lead-acid batteries. Three voltage grades are equipped with tailored high-current BMS systems. Compact footprint and low weight enable seamless compatibility across multiple golf cart models.

Specially matched 58.4V 22A charger realizes fast charging: 2.38h for 50%‑100% charging cycle, 4.7h for full 0%‑100% charging cycle. Immediate charging upon SOC<10% is advised to prevent deep discharge and optimize cycle life.

Delivers stable power output, excellent temperature adaptability, and easy installation, making it an ideal LiFePO₄ upgrade for traditional lead acid batteries. Its reliable performance ensures a smooth and convenient transition to lithium power.

Designed for reliable outdoor charging, it provides stable and safe charging output with a wide operating and storage temperature range, ensuring excellent environmental adaptability for golf cart LiFePO₄ batteries.

Smart 2.8-inch touch monitoring display with ultra-wide 10–90V voltage compatibility. Low power consumption and broad temperature adaptability allow real-time battery data check conveniently.

Built for versatile applications, this LiFePO₄ battery is compatible with Club Car, EZGO, Yamaha and more, providing a reliable lithium upgrade for golf carts, ATVs, sightseeing buses, mobility scooters and riding mowers.
