SBS05150200, Victron Energy SBS-10MT Long Range 10 Metre Battery Temperature Sensor. Smart Battery Sense is a wireless battery voltage and temperature sensor for Victron MPPT solar chargers. With voltage and temperature detection in place, batteries will be charged better, improving charging efficiency and extending battery life. Measuring the voltage at the battery bank terminals avoids voltage loss errors caused by cable resistance and ensures the correct charging voltage. For lead-acid batteries, battery temperature data is used to adjust charging voltages: cold batteries require a higher charging voltage, while hot batteries require a lower charging voltage. For lithium batteries, temperature data is used to deactivate charging when they are too cold: charging lithium batteries at temperatures close to or below freezing causes permanent damage to the cells. The connection between the Smart Battery Detector and one or more Solar Chargers is wireless: it uses the VE.Smart Network, a wireless technology based on Bluetooth Smart. The transmitted information can be used simultaneously by one, two or more Solar Chargers connected to the same 12V, 24V and 48V battery bank. The Smart Network is configured using the VictronConnect application.
