BLUETTI B500K V2 Expansion Battery | 5,120Wh LiFePO₄ Module

Equipment Type: Modular Lithium Iron Phosphate battery expansion unit. Primary Applications: Residential grid-tie backup, off-grid storage arrays, and high-load mobile power systems.

Performance Specifications

  • Energy Capacity: 5,120Wh
  • Cell Chemistry: Lithium Iron Phosphate (LiFePO₄)
  • Cycle寿命: 4,000+ partial cycles retaining ≥80% rated capacity
  • Dual Expansion Interface: 58.4VDC Max, 90A Max combined throughput
  • Maximum Charge Rate: 60A
  • Maximum Discharge Rate: 70A
  • Environmental Rating: IP20 (indoor, climate-controlled deployment only)

Safety Features and Certifications

Integrated Battery Management System continuously tracks individual cell voltages, temperature gradients, and current draw. The LiFePO₄ formulation provides inherent thermal runaway resistance, while automated protection circuits enforce hard limits on over-charge, over-discharge, and short-circuit conditions. No third-party certification marks provided in source documentation.

Installation and Maintenance Requirements

Secure in dry, ventilated zones away from moisture sources. Connect to compatible host stations via dedicated expansion ports. Initial commissioning requires mechanical coupling and automatic protocol handshake. Annual preventive maintenance includes terminal torque verification, connector cleaning, and synchronized firmware updates delivered through the primary controller interface.

Warranty and Service Information

Covered by a four-year limited warranty addressing manufacturing defects and accelerated capacity fade. Field repairs are prohibited; defective units require authorized diagnostic evaluation and must be routed through certified service channels for replacement processing.

Branding/References

Manufacturer: BLUETTI
Model Designation: B500K V2 (BlueCell 500)
Host Platform Compatibility: Apex300, AC500, AC300, AC200MAX

Differentiators

Engineered with a true dual-channel expansion topology that routes independent communication and power lines to multiple host ports simultaneously. This architecture eliminates single-branch throughput bottlenecks, sustaining high-amperage continuous loads while supporting decade-plus system longevity across scalable energy networks.
