Victron Energy Battery Monitor Temperature Sensor - BMV-702-712

This sensor is compatible with the Victron Energy BMV-712 Smart and BMV-702 battery monitors.

While it is technically possible to modify the cable length, it is strongly discouraged and voids any manufacturer support. It is best to use the sensor with its original cable length.

When the temperature sensor is connected, the monitoring of the second battery voltage and the center voltage are disabled.

The sensor provides battery temperature data to the BMV monitor, allowing Victron products to adjust charging parameters for better accuracy, preventing overcharging or undercharging in various temperature conditions.

Position the sensor probe near the battery to accurately measure its ambient temperature. Avoid direct contact with battery terminals or internal components.

No, the temperature sensor is powered by the BMV battery monitor and does not require its own power source.

Ensure the sensor is securely connected to the BMV monitor. Verify that the sensor cable is not damaged. Check that the BMV monitor is configured to recognize the temperature sensor.

This is expected behavior. When the temperature sensor is connected and active, it occupies the input port used for secondary voltage monitoring, thus disabling the display of second battery voltage and center voltage.

Double-check the sensor connection at the BMV monitor. Try disconnecting and reconnecting the sensor. Ensure the BMV firmware is up-to-date, as older versions might have compatibility issues.
