    Frequently Asked Questions (FAQ)
    Q What battery chemistry is used in the BS06 series, and why is it preferred for energy storage?
    The BS06 series uses LiFePO4 (Lithium Iron Phosphate) battery chemistry. LiFePO4 is widely preferred for stationary energy storage due to its excellent thermal stability, long cycle life (≥6000 cycles), and high safety profile compared to other lithium-ion chemistries. It also maintains consistent performance across a wide temperature range.
    Q How many BS06 battery units can be connected in parallel, and what is the maximum system capacity?
    Up to 5 units can be connected in parallel. Using the largest model (BS06-46-S/6S) at 46.08kWh nominal energy, a 5-unit parallel configuration can deliver up to 230.4kWh of nominal energy, making it suitable for large-scale commercial or industrial energy storage applications.
    Q What communication interfaces does the BS06 battery support for system integration?
    The BS06 series supports both CAN (Controller Area Network) and RS485 communication interfaces. These protocols allow seamless integration with a wide range of inverters, energy management systems (EMS), and building automation platforms, ensuring compatibility with most modern solar and hybrid energy storage systems.
    Q What is the expected cycle life and warranty coverage for the BS06 battery series?
    The BS06 series is rated for ≥6,000 charge/discharge cycles tested at 25℃, 0.5C/0.5C rate, 90% DOD, with 70% end-of-life (EOL) capacity retention. The warranty period is 5+5 years, providing comprehensive coverage and long-term peace of mind for system owners and installers.
    Q Is the BS06 battery suitable for outdoor installation? What is its IP and anti-corrosion rating?
    Yes, the BS06 series is rated IP65, meaning it is fully dust-tight and protected against water jets, making it suitable for outdoor environments. Additionally, its C4 anti-corrosion grade ensures reliable performance in high-humidity, coastal, or industrially polluted environments where corrosion resistance is essential.
    Q What safety certifications does the BS06 battery hold, and what built-in protection features does it include?
    At the cell level, the BS06 battery holds UN38.3, MSDS, IEC62619, CE, UL1973, and UL2054 certifications, meeting rigorous international safety standards. At the pack level, it is certified to UN38.3 and MSDS. Built-in protection includes a Battery Management System (BMS) and a circuit breaker, safeguarding against overcharge, over-discharge, short circuit, and thermal events.
