    ❓ Frequently Asked Questions
    Q What type of battery does this BMS support?
    This BMS is designed to support LiFePO4 (Lithium Iron Phosphate) battery chemistry, which is known for its superior thermal stability, long cycle life, and enhanced safety compared to other lithium-ion chemistries.
    Q What is the maximum input charging current this BMS can handle?
    The typical input charging current is 80A. It is important not to exceed this value to ensure safe and reliable operation of the battery management system.
    Q What is the output discharging voltage range?
    The output discharging voltage ranges from a minimum of 46V to a maximum of 74V, with a typical operating voltage of 64V. This makes it suitable for 20S LiFePO4 battery pack configurations.
    Q What does "20S" battery link configuration mean?
    "20S" refers to 20 battery cells connected in series. This configuration determines the overall pack voltage. For LiFePO4 cells, a 20S configuration results in a nominal pack voltage suitable for high-power applications.
    Q What is the continuous output discharging current limit?
    The continuous output discharging current must be kept at or below 120A. Exceeding this limit may trigger the BMS protection mechanism or cause permanent damage to the system.
    Q What are the physical dimensions of the battery module?
    The battery module measures 168 × 83 mm. Please ensure adequate space and proper mounting clearance when integrating this module into your system design.
