The 3S 15A High-Current Smart Protection Board (SMBUS-Compatible) is engineered to meet the rigorous demands of industrial and commercial applications, offering enhanced power handling with a robust 15A continuous discharge capability. Designed for extreme environments, it operates across an expanded discharge temperature range of -25°C to 65°C(adjustable) and supports charging in sub-zero to high-temperature conditions (-5°C to 55°C, adjustable), ensuring reliability in challenging climates. Integrated SMBUS communication enables precise real-time monitoring of battery health metrics, while advanced safeguards—including overvoltage, undervoltage, overcurrent, and short-circuit protection—deliver unmatched safety for high-power systems. Ideal for electric mobility, industrial automation, and large-scale energy storage, this board combines high-performance durability with intelligent battery management.
