Bluetti B300K

The Streamlined Muscle for High-Capacity Power Stacking

The BLUETTI B300K is the ultimate capacity booster designed for users who prioritize raw storage efficiency and value per watt-hour. Serving as the modular counterpart to the classic B300 lines, the B300K sheds auxiliary output panels to focus entirely on pure, high-efficiency energy density. By optimizing the internal layout with next-generation square cells, it achieves a 16% higher energy density and a significantly improved lifespan, making it the perfect choice for building out expansive home backup banks, heavy-duty overlanding setups, or dedicated solar micro-grids.

Automotive-Grade Safety & AI-BMS Architecture

The core of the B300K features premium Lithium Iron Phosphate (LiFePO4) cell chemistry managed by a cutting-edge AI-BMS (Artificial Intelligence Battery Management System). This advanced circuitry dynamically monitors voltage, current, and temperature thresholds across internal arrays to mitigate overheating and prevent over-discharging. Encased in a scuff-resistant, vibration-dampening aluminum chassis with integrated side handles and an efficient cooling fan, this rugged unit is engineered to endure harsh daily deployments without failing.

Key Performance Features:

• Universal Multi-Platform Compatibility: Scale up your ecosystem effortlessly. The B300K integrates seamlessly into standard BLUETTI platforms—including the AC200MAX, AC200L, AC300, and AC500 lines. For instance, pairing a stack of B300K batteries with an AC500 mainframe allows you to build a home powerhouse scaling all the way up to a massive 16,588Wh of pure off-grid storage.

• Industry-Leading Cycle Life: Get more out of your investment. While most conventional power storage units degrade quickly, the B300K boasts a highly resilient 4,000+ complete charge-and-discharge cycles before easing to 80% of its native original capacity, providing over 10 years of reliable performance.

• Emergency Standalone Power Port: Even when uncoupled from a master host station, the B800K doesn’t leave you stranded. The front dashboard features an integrated standalone 12W USB-A output (5V/2.4A), allowing you to plug in and charge emergency items like smartphones, tablets, or portable fans directly from the expansion block.

• Blistering 45-Minute Turbo Charging: Minimize your system downtime. When locked into high-powered host modules like the AC300 or AC500, the B300K communicates via a heavy-duty proprietary P090A expansion connection link, absorbing utility juice to reach an 80% charge level in just 45 minutes.

• Advanced Wireless Synchronization: Keep tabs on your entire system from anywhere. When linked into your host unit, the B300K transfers cell data metrics wirelessly to the central module, letting you track individual battery pack states of charge, cell balances, and performance metrics inside the unified BLUETTI smartphone application.
