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 (15.3×12.4×10.0 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.

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.

Premium Grade-A LiFePO₄ cells deliver stable power, consistent performance, excellent durability, and a longer service life, ensuring dependable energy for golf carts in daily use.

The 250A Smart Relay BMS provides advanced protection by cutting power during faults, suppressing electrical arcs, limiting inrush current, and safeguarding the battery and connected devices.

With IP65 dual-layer sealing, the battery effectively blocks water, dust, and debris, helping protect internal components and deliver reliable, consistent performance in demanding golf course conditions.

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.

Monitor battery status with ease through the built-in touchscreen or KeepKnow APP. View key data such as SOC, voltage, temperature, and operating status in real time, wherever you are.

With a maximum driving range of up to 52 miles, it delivers reliable power for everyday use. Strong peak discharge capability provides consistent power on uphill slopes, muddy roads, and other challenging terrain.

The matched 58.4V 22A charger enables fast charging, reaching 50%–100% in just 2.4 hours and 10%–100% in 4.3 hours. Charging when SOC falls below 10% helps prevent deep discharge and support longer cycle life.

Upgrade from traditional lead-acid to KeepKnow LiFePO₄ power. Available in 36V, 48V, and 72V options, with high-current BMS and compact designs for reliable performance across various golf cart models.

All essential accessories are included for smooth and convenient installation, while the user manual provides clear instructions for proper setup, operation, and everyday use.

Designed for stable power, easy installation, and reliable performance, it supports golf carts, ATVs, sightseeing vehicles, mobility carts, and riding lawn mowers.

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.
