DALY Lithium-ion Battery Charger Protection Module (BMS) 20S 60A 72V
The DALY Module (BMS) 20S 60A 72V Lithium-ion Battery Management System (BMS) is a professional battery protection module engineered for 72V lithium-ion battery packs consisting of twenty cells connected in series. It continuously monitors individual cell voltages, charging and discharging currents, and battery temperature to ensure safe, stable, and efficient battery operation. The integrated protection circuitry safeguards the battery pack against overcharging, over-discharging, overcurrent conditions, and short circuits, helping to maintain battery health and system reliability.
Designed for demanding electric mobility and energy storage applications, this BMS incorporates an automatic cell balancing function that equalizes cell voltages throughout the battery pack. Proper balancing improves battery efficiency, maximizes available capacity, extends battery lifespan, and enhances overall performance. Its durable construction makes it suitable for electric vehicles, renewable energy systems, industrial equipment, and custom battery pack projects.
