Victron Temperature Sensor for BMV-712, BMV-702, and SmartShunt Battery Monitors

Precision Battery Temperature Monitoring for Enhanced Charging Accuracy

The Victron Temperature Sensor (ASS000100000) is an essential accessory for your Victron BMV-712 Smart, BMV-702, or SmartShunt battery monitor. By measuring the main battery temperature, it enables your monitoring system to apply temperature-compensated charging, which adjusts charge voltages based on actual battery conditions. This helps prevent overcharging in high temperatures and undercharging in cold conditions, extending battery life and improving system reliability.

Designed specifically for Victron battery monitors with temperature support, this sensor integrates seamlessly via VE.Smart Networking (BMV-712 and SmartShunt) or direct connection (BMV-702 with VE.Smart Dongle). The sensor probe is embedded in a robust M10 (3/8"-16) ring terminal that attaches directly to the positive battery terminal, ensuring accurate and responsive temperature readings.

Key Features

• Measures main battery temperature for precise charge voltage adjustment
• Compatible with BMV-712 Smart, BMV-702, and SmartShunt battery monitors
• Integrated M10 (3/8"-16) ring terminal for direct battery terminal mounting
• Pre-crimped wire ferrules for quick, secure connection to the monitor
• Supports VE.Smart Networking for wireless data sharing with compatible chargers
• Enables high and low temperature alarms to protect your battery
• Temperature range: -20 to +50 °C with ±1 °C accuracy

Why Temperature Monitoring Matters

Lead-acid and lithium batteries are sensitive to temperature fluctuations. Without temperature compensation, a charger may apply incorrect voltages, leading to reduced capacity, accelerated aging, or even permanent damage. The Victron Temperature Sensor provides real-time data to your battery monitor, allowing connected chargers (via VE.Smart Networking) to dynamically adjust charge parameters. This is particularly valuable in Australian conditions, where battery compartments can experience extreme heat or cold.

Simple Installation

Installation is straightforward: attach the M10 ring terminal to the positive battery post, then connect the red and black wires to the designated terminals on your battery monitor. For the BMV-712 Smart and BMV-702, the black wire goes to the +B2 terminal and the red wire to +B1. For the SmartShunt, connect black to the Aux terminal and red to Vbatt+. Once connected, the monitor automatically detects the sensor and begins displaying temperature data.

Compatibility Note

This sensor is designed exclusively for the BMV-712 Smart, BMV-702, and SmartShunt. It is not compatible with other Victron products such as the BMV-700, BMV-710, or MultiPlus inverter/chargers, which use a different temperature sensor. Please verify your device model before ordering.
