BMS Sensor (AIS Dual) – Dual Current and Voltage Sensor for Battery Management Systems
The BMS Sensor (AIS Dual) is a high-precision dual-sensor module designed for advanced battery management systems (BMS). It accurately measures both charge and discharge current as well as voltage levels in real time. Ideal for integration with smart BMS platforms, it provides the essential data for battery diagnostics, balancing, and protection.
