The Victron Temperature Sensor (ASS000100000) is the official accessory for maximising the accuracy of your BMV-702, BMV-712 Smart, or SmartShunt battery monitor. By measuring your main battery's real-time temperature via an NTC thermistor, this sensor feeds precise data directly into your Victron battery monitor — allowing the unit to apply temperature-compensated state-of-charge calculations that are far more accurate than voltage-based estimates alone. Backed by Victron's industry-leading 5-year warranty, it is designed to work seamlessly within the Victron Energy ecosystem and connects directly to the dedicated temperature port on compatible monitors.

For Australian caravan, RV, motorhome, and 4WD enthusiasts managing house battery systems in harsh outback conditions, temperature accuracy is critical — battery capacity and charging behaviour changes dramatically between cold winter mornings in the high country and scorching summer afternoons in the Australian desert. This sensor enables your BMV monitor to trigger configurable high and low temperature alarms, protecting your AGM, gel, or lithium battery from damaging charge cycles in extreme heat or cold. Whether you're free-camping off-road, crossing the Nullarbor, or parked up at a remote station, this compact sensor gives you the confidence that your battery management system is working with real-world data rather than guesswork.
