Spare battery temperature sensor for the Inverter RS Smart Solar. The Victron Energy Temperature Sensor Type C is designed to provide accurate battery temperature readings for compatible Victron equipment. When connected to supported chargers and power management devices, the sensor allows the system to adjust charging behavior based on real time temperature conditions. This helps protect batteries from overcharging in warm environments and ensures proper charging in colder conditions. The Type C sensor is simple to install and offers stable, consistent measurements for both lithium and lead acid battery banks. It is suitable for use in RVs, marine systems, off grid power installations, and any application where temperature compensated charging is important. This sensor contributes to improved battery performance, safety, and long term reliability by giving the charger the information it needs to manage voltage correctly.
