Victron Energy ASS000100000 Temperature Sensor for BMV-702/712/SmartShunt

Protect your battery investment with accurate temperature monitoring and charging optimisation.

Product Overview

The Victron Energy ASS000100000 is a precision temperature sensor designed specifically for BMV-702, BMV-712 battery monitors and SmartShunt devices. This sensor continuously measures main battery temperature and communicates data to your Victron monitoring system, enabling temperature-compensated charging that extends battery life and prevents damage from over-temperature conditions. When connected, the sensor allows you to configure high and low temperature alarms that alert you before batteries reach dangerous operating conditions. Essential for Australian touring and off-grid setups where batteries experience extreme temperature swings, this sensor ensures your expensive AGM, gel, or lithium battery bank operates within safe parameters. The sensor integrates seamlessly with Victron's VictronConnect app for remote monitoring and alarm configuration via Bluetooth.

Features & Benefits

Temperature-Compensated Charging for Extended Battery Life – Adjusts charging voltage based on actual battery temperature, preventing overcharging in hot conditions and undercharging in cold conditions that dramatically reduce battery capacity and lifespan in Australian climate extremes.

Configurable High and Low Temperature Alarms – Sets custom alarm thresholds that trigger warnings before batteries reach dangerous operating temperatures, preventing thermal runaway in lithium systems or permanent capacity loss in lead-acid batteries during extreme weather.

Essential for Touring and Off-Grid Applications – Critical for caravans, motorhomes, and 4WD setups where batteries mounted in engine bays, under bonnets, or in sealed battery boxes experience temperature extremes that standard charging profiles can't accommodate safely.

Seamless Victron Ecosystem Integration – Plugs directly into BMV-702, BMV-712, and SmartShunt devices without additional wiring or configuration complexity, instantly enabling temperature monitoring through existing Victron monitoring infrastructure.

Remote Monitoring via VictronConnect App – View real-time battery temperature and receive alarm notifications on your smartphone through Bluetooth connection, allowing you to monitor battery conditions without physically checking the battery compartment.

Protects Premium Battery Investments – Prevents premature failure of expensive AGM, gel, and lithium battery banks by ensuring charging systems respond to actual battery temperature rather than fixed voltage setpoints that ignore environmental conditions.

Precise Temperature Measurement – Delivers accurate battery temperature readings to Victron monitoring systems, enabling informed decisions about charging rates, load management, and system operation during temperature extremes.

Frequently Asked Questions

Which Victron devices does this sensor work with?

This sensor is compatible with Victron BMV-702, BMV-712 battery monitors, and SmartShunt devices only. It does not work with other Victron products or non-Victron battery monitors.

Why do I need a temperature sensor for my battery monitor?

Battery charging voltage must change based on temperature to prevent overcharging when hot or undercharging when cold, both of which dramatically reduce battery life and capacity.

How does temperature compensation work?

The sensor measures actual battery temperature and your Victron charger automatically adjusts charging voltage to match optimal levels for that temperature, extending battery life and improving charge efficiency.

Can I set my own temperature alarm thresholds?

Yes, using the VictronConnect app you can configure custom high and low temperature alarm levels appropriate for your specific battery type and operating environment.

Where should I mount the temperature sensor?

Mount the sensor directly on the battery terminal or battery casing in contact with the battery to measure actual battery temperature, not ambient air temperature in the battery compartment.
