Description (from PDP, plain text)
The BLUETTI B300K2 Expansion Battery is an updated variant of the B300K module, specifically optimized for space efficiency and tidier cable management. While it shares the same high-density 2,764.8Wh capacity and automotive-grade LiFePO4 chemistry as the standard B300K, the "K2" version is distinguished by its 90-degree connection plug and specialized compatibility with the Apex300 (AC300A) series. This 90-degree design allows the expansion cable to sit flush against the unit, significantly reducing the clearance needed behind the battery stack. This makes it the ideal choice for installation in tight spaces like shallow cabinets, RV storage compartments, or narrow hallways where protruding cables would be a hazard or obstruction. Key Features Space-Optimized 90° Connection: The right-angle connector minimizes cable protrusion, allowing the battery stack to be pushed closer to walls or enclosures for a cleaner, safer installation. Massive 2.7kWh Capacity: Adds 2,764.8Wh of reliable storage to your system. When paired with the Apex300/AC300 series, it can scale to meet whole-home backup needs. Apex300 Optimized: Specifically designed to work seamlessly with the Bluetti Apex300 using the included CA90 90-degree cable, ensuring a high-current, stable connection. Automotive-Grade LiFePO4: Features square battery cells rated for over 4,000 charge cycles, providing more than a decade of daily use while maintaining 80% of its original capacity. Intelligent AI-BMS: Equipped with a smart Battery Management System that proactively monitors voltage, current, and temperature to ensure peak safety and efficiency. Standalone USB Port: Includes a built-in 12W USB-A port, enabling you to charge smartphones or tablets directly from the battery module without needing a main power station.
