In today’s world, where energy efficiency, reliability, and smart management are becoming increasingly critical, businesses and home users alike are seeking energy solutions that combine high performance with intelligent monitoring. KeepKnow’s 48V 100Ah LiFePO4 Server Rack Battery offers a next-generation solution for data centers, home energy storage, and off-grid applications, delivering both powerful performance and smart features in a compact and user-friendly design.

Intelligent Monitoring and Real-Time Management

One of the standout features of the KeepKnow 48V 100Ah battery is its built-in LCD screen, which allows users to monitor battery status instantly. Whether you’re checking voltage, current, state of charge, or other key performance metrics, the LCD provides clear, real-time data.

For even greater convenience, the battery comes with WiFi and Bluetooth connectivity, enabling seamless integration with the KeepKnow smart app. Through the app, users can track detailed performance and health metrics, receive alerts, and manage their battery system remotely. This level of visibility is particularly valuable for server racks, home energy setups, and off-grid solar systems, where maintaining battery health is critical to uninterrupted operation.

Compact and Flexible Design for Space-Limited Environments

Space efficiency is a major concern in server rooms and home energy installations. The KeepKnow 48V 100Ah battery measures 18.9 × 17.4 × 5.2 inches, making it an ideal solution for setups where space is at a premium. Its tool-free press-to-lock quick-connect terminals allow for effortless installation without the need for specialized tools, while the anti-loosening plug design ensures secure connections during operation.

Designed to fit standard 3U server racks, the battery also includes stacking brackets for flexible deployment. Whether you need a compact single battery or a modular multi-battery setup, KeepKnow provides a solution that adapts to your needs.

Built-In Safety and Robust Protection

Safety is at the heart of the KeepKnow 48V 100Ah battery. It features an intelligent built-in fire suppression system designed to mitigate risk in the unlikely event of thermal anomalies. Thick #4AWG high-current cables prevent overload, while the durable metal housing provides long-lasting protection for both the battery and connected equipment.

This robust design ensures that critical systems—whether base stations, server racks, or home energy storage—remain protected against environmental hazards, electrical faults, and physical impacts.

Advanced Lithium Technology for Maximum Performance

At the core of the KeepKnow battery are 16 A-grade LiFePO4 cells paired with an upgraded smart 100A BMS (Battery Management System). This combination delivers several key advantages:

• Excellent Cell Consistency: Ensures reliable performance across all cells.

• Low Self-Discharge: Maintains charge longer during idle periods.

• Extended Cycle Life: Achieves 4000+ cycles at 100% DOD and 6000+ cycles at 80% DOD, far surpassing traditional lead-acid alternatives.

• Wide Operating Temperature Range: Charges between 0°C–55°C and discharges from -20°C–60°C, making it suitable for extreme climates.

These features make the KeepKnow battery a dependable solution for users who need high performance, long-lasting energy storage, and minimal maintenance.

High Capacity and Scalability

The KeepKnow 48V 100Ah battery supports up to 15 batteries in parallel, providing a massive 76.8kWh of total energy. With a max continuous charge/discharge current of 100A and a 200A peak current, the battery can handle high power demands with ease.

Compared to traditional lead-acid setups, KeepKnow batteries are 80% lighter and 70% smaller, while delivering the same or greater energy. This makes them a practical choice for applications where space and weight are critical considerations.

Seamless Compatibility with Popular Inverters

Integration with existing energy systems is made easy thanks to KeepKnow’s support for popular inverters such as Victron, Pylontech, Luxpower, Sol-Ark, DEYE Growatt, GoodWe, and more. The battery is equipped with CAN and RS485 ports, along with a communication cable for plug-and-play connectivity.

Whether you are building an off-grid solar setup, a home energy storage system, or an industrial battery bank, KeepKnow ensures smooth communication and interoperability with your inverter and monitoring ecosystem.

Multiple Charging Options for Flexible Energy Management
