Victron Energy Temperature Sensor for BMV-702/712 — Dedicated probe for accurate battery temperature sensing and charge adjustment

Victron Energy Temperature Sensor for BMV-702/712 provides a dedicated temperature probe that connects to compatible BMV battery monitors so charging can account for battery temperature.

This compact temperature sensor is built specifically to work with the Victron Energy BMV-702 and BMV-712 battery monitors. It supplies a temperature reading the monitor can use to adjust charging behavior and improve the monitor's battery condition awareness. The accessory is simple to install following the BMV manual and is electrically compatible only with the two monitor models listed.

How does the temperature sensor integrate with my BMV-702 or BMV-712?

The sensor plugs directly into the dedicated temperature input on a BMV-702 or BMV-712 and the monitor then displays and logs the measured temperature. No additional adapters are required, but the sensor is not compatible with other Victron monitors.

• Direct plug-in connector designed for BMV-702/712 input
• Monitors temperature for display and logging
• Installation steps documented in the BMV user manual

What trade-offs should I expect when using the sensor?

When the temperature sensor is connected, some BMV functions are mutually exclusive: the monitor cannot simultaneously provide second-battery voltage and midpoint voltage sensing. That's an intentional limitation of the monitor's inputs, not the sensor itself.

• Second-battery voltage monitoring is disabled when sensor is connected
• Midpoint voltage monitoring also becomes unavailable
• Temperature sensing prioritized to support better charge management

How does temperature data help with battery charging and monitoring?

Temperature affects battery behavior, and feeding real-time temperature into the monitor helps the system account for colder or warmer conditions during charge cycles. The BMV uses that information to calculate state-of-charge and may alter charge recommendations accordingly.

• Improves the monitor’s understanding of battery condition
• Provides temperature readings for logs and diagnostics
• Enables temperature-informed charging adjustments via the monitor

How difficult is installation and where should the sensor be placed?

Installation is straightforward for anyone comfortable following the BMV manual: route the cable, attach the probe to the battery or battery environment, and plug into the monitor. For best results mount the sensor where it contacts or closely senses the battery temperature but avoid direct contact with terminals or moving parts.

• Follow mounting and routing guidance in the BMV manual
• Place probe for representative battery temperature readings
• Avoid terminal contact and secure cable to prevent chafing

Who is this for: The Victron Energy Temperature Sensor for BMV-702/712 is aimed at boaters, RV owners, off-grid solar users, and anyone using a BMV-702 or BMV-712 who wants temperature-aware battery monitoring. If you rely on accurate battery state reports and use one of the two compatible Victron monitors, this sensor gives the monitor the temperature input it needs. If you need second-battery or midpoint voltage sensing at the same time, evaluate your monitoring priorities since those functions cannot run concurrently with the temperature probe connected.
