Description (from PDP, plain text)
The BLUETTI B300K Expansion Battery is a high-density, modular power solution designed to significantly increase the storage capacity of existing BLUETTI power systems. Positioned as a more streamlined and cost-effective alternative to the original B300, the B300K focuses on "pure battery" performance, offering a more compact footprint and a lighter weight while maintaining long-term durability. With a 2,764.8Wh capacity, it utilizes automotive-grade LiFePO4 cells that deliver an industry-leading lifespan of over 4,000 cycles. It is specifically designed to stack seamlessly with BLUETTI’s flagship models, allowing for massive energy configurations—up to 16,588Wh when paired with the AC500. Key Features Modular Storage Expansion: Easily scales your energy setup. Connect up to 4 units to an AC300 or up to 6 units to an AC500 to build a massive home backup or off-grid system. Next-Gen Battery Chemistry: Features square LiFePO4 cells and AI-BMS (Battery Management System) technology, ensuring the unit remains safe and efficient for over 10 years of daily use. Space-Saving Design: Approximately 7kg lighter and more compact than the previous B300 model, making it easier to handle and stack in tight spaces like RVs or utility closets. Rapid Dual Charging: When integrated into an AC300 or AC500 system, the B300K can reach an 80% charge in as little as 45 minutes. Standalone Emergency Port: Includes a built-in 12W USB-A port, allowing you to charge smartphones or tablets directly from the battery without needing a power station in an emergency. Rugged Construction: Encased in a durable aluminum alloy shell with an efficient cooling fan to ensure reliability in demanding environments.
