BLUETTI B300K Expansion Battery | 2,764.8Wh

Equipment Type and Primary Applications: Modular LiFePO4 storage module delivering 2,764.8Wh capacity engineered for off-grid microgrids and backup power distribution. Performance Specifications: 2,764.8Wh nominal capacity with 4,000+ cycle durability. Integrates natively with Apex300, AC200L, AC200MAX, AC300, and AC500 inverters. Reaches 80 percent charge in 45 minutes using 50A cables with compatible hosts. Scales to 58kWh maximum via 18-unit parallel arrays. Safety Features and Certifications: Internal battery management system enforces strict voltage and temperature limits. Automotive-grade LiFePO4 chemistry ensures thermal stability and suppressed thermal runaway risk. Installation and Maintenance Requirements: Mount on flat, ventilated surfaces. Connect using designated parallel wiring harnesses only. Verify host firmware before initialization. Annual terminal inspection suffices; sealed modules require zero fluid maintenance. Warranty and Service Information: Four-year coverage for manufacturing defects and capacity deviation beyond rated cycles. Certified distributor network handles repair and module replacement. Branding/References: Manufacturer: BLUETTI. Model: B300K (BlueCell 300). Technical documentation details electrical interfaces and host pairing matrices. Differentiators: Single-bank scaling supports 18 synchronized units to 58kWh without auxiliary combiners. Dedicated 50A charging pathway cuts recovery time, maximizing generator efficiency during extended outages.
