JBD Smart BMS 7-21S 300A (AP21S002) WITH RELAY (494f)

Product Details

The Smart BMS 7-21S 300A Same Port for Charge and Discharge (AP21S002) is a versatile and efficient battery management system designed for 7 to 21-series lithium-ion or lithium iron phosphate (Li-ion/LiFePO4) battery packs. With a high current rating of 200A, this BMS can support high-power applications while maintaining optimal performance and safety. The system features a single-port design, which simplifies the wiring process by combining both charging and discharging functions into one port, reducing complexity and minimizing space requirements. This Smart BMS is equipped with advanced protection features, including overcharge, over-discharge, overcurrent, short-circuit, and temperature monitoring, ensuring the battery pack remains safe during operation. Additionally, it provides real-time monitoring of key parameters such as voltage, current, and temperature, allowing users to easily track the battery's health and performance. Ideal for electric vehicles, power tools, energy storage systems, and other high-demand applications, the AP21S002 ensures efficient power management and extends the life of the battery pack. The active balancing function further improves energy efficiency by redistributing charge between the cells, optimizing the performance of the battery pack over time. The compact and reliable design of this BMS makes it an excellent choice for users seeking a robust solution for their 7-21S Li-ion/LiFePO4 battery packs.
