BYD Unveils 4th-Gen Blade Battery Home Storage System with Unprecedented Scalability and Efficiency

The system’s modular architecture allows homeowners to customize capacity from a base unit of 5.9 kWh to a robust 89 kWh configuration using stacked cabinets. Each 27.3 kg module delivers 2.97 kWh, offering a 15% space-saving advantage over conventional lithium iron phosphate (LFP) systems. Performance benchmarks set new industry standards, with a continuous output of 25.6 kW at 50A and a peak surge of 50.18 kW for 15 seconds-enough to simultaneously power air conditioning, refrigeration, and electric vehicle charging during outages. The HVB’s extended -30°C to +60°C operational range and 96% round-trip efficiency outperform 2025 market averages, while its 6,000-cycle lifespan at 80% depth of discharge ensures decade-long reliability.
