BLUETTI B4810 5,120Wh LiFePO4 Battery Bank

Equipment Type: BLUETTI B4810 lithium iron phosphate (LiFePO4) battery bank.

Primary Applications: Off-grid housing, RV auxiliary power, marine electrical systems, and dedicated home backup power infrastructure.

Performance Specifications

  • Rated energy: 5,120Wh at 51.2V nominal and 100Ah.
  • Cycle durability: 6,000 full cycles while retaining 70% rated capacity.
  • Continuous charge and discharge: 100A maximum in each direction.
  • Peak discharge: 200A for up to 30 seconds.
  • Operating temperature: -20°C to 55°C during charging and discharging.
  • Expansion capacity: Up to 122.88kWh through a 24P parallel configuration without protocol alteration.

Safety Features and Certifications

  • Cell-level thermal protection provides immediate cutoff during abnormal heat buildup.
  • IP65-rated polymer enclosure protects against dust ingress and water spray.
  • Compliance includes UN38.3 transport protocols, FCC electromagnetic limits, CE safety directives, RoHS material restrictions, UL fire ratings, and MSDS logistical handling.

Installation and Maintenance Requirements

  • Mounts to compatible inverters or DC breakers using standard 19-inch rack or flat-panel rails.
  • Provide 75mm rear clearance for airflow.
  • Initial deployment pairs automatically with supported host controllers through CANbus.
  • Factory-sealed cells eliminate sulfuric acid handling and electrolyte-level checks.
  • Re-torque terminals every six months and run self-diagnostic routines monthly.

Warranty and Service Information

Five-year manufacturer warranty covers premature capacity fade and defective internal circuitry. Replacement modules ship from regional fulfillment centers after serialized-unit validation. Certified partner facilities provide technical escalation with a standard 48-hour diagnostic turnaround.

Branding/References

Manufacturer: BLUETTI. Model: B4810. Reference documentation includes the B4810 engineering specification sheet, schematic diagrams, termination pinouts, and third-party test results.

Differentiators

Dual 100A charge and discharge architecture avoids external contactor staging. Thermal dispersion routing and 24P scalability support stable voltage performance during sudden compressor startup loads.
