Description (from PDP, plain text)
The BLUETTI B500K1 Expansion Battery (B500K) is a heavy-duty energy storage module designed for large-scale home backup and off-grid solar systems. Boasting a massive 5,120Wh capacity, it is the highest-density expansion module in the BLUETTI lineup, offering nearly double the storage of the standard B300 series in a single unit. Equipped with premium LiFePO4 cells, the B500K1 is built for longevity with a lifespan of over 4,000 cycles. Its advanced "Next-Gen Design Architecture 2.0" features a wireless internal layout that minimizes cabling, improving both reliability and thermal efficiency. This model is specifically designed for semi-permanent or mobile setups, featuring mounting holes for wall/rack installation and compatibility with BLUETTI’s heavy-duty trolleys. Key Features Massive 5.12kWh Capacity: A single unit provides enough energy to run critical home appliances (like a large refrigerator or well pump) for extended periods during an outage. High Scalability: Designed for ambitious setups. When paired with the Apex 300 or AC500 systems, you can chain multiple units together to reach a staggering 100kWh of total storage. Next-Gen Internal Architecture: The cable-free internal layout reduces failure points and makes the unit more compact and resilient to the vibrations of van life or travel. Superior Cold Resistance: Engineered to perform in harsh conditions, maintaining a stable discharge even in temperatures as low as -20°C. Universal Ecosystem Compatibility: Works seamlessly with the Apex 300, AC300, AC200L, and AC200MAX. It can also connect to the AC500 using a separate adapter cable. Direct DC Charging Hub: When used with the optional Hub D1 accessory, the B500K1 can serve as a high-capacity 700W DC power hub for RVs or off-grid cabins.
