Victron Temperature Sensor for Precision Battery Management
Optimise Charging and Protect Your Power System with Accurate Temperature Monitoring
The Victron Temperature Sensor (ASS000001000) is a purpose-built accessory that enables temperature-compensated charging and real-time thermal monitoring across Victron Energy systems. By feeding precise battery temperature data to your inverter/charger or GX device, it helps maintain optimal charging voltages, extends battery service life, and reduces the risk of thermal runaway in lithium banks. This sensor is an essential component for anyone seeking reliable, automated energy management in mobile, marine, or off-grid installations.
Unlike generic sensors that may lack proper calibration or ruggedness, this Victron sensor is engineered for seamless integration with MultiPlus, Quattro, and the Cerbo GX, Ekrano GX, and Venus GX platforms. It also supports VE.Can MPPT solar charge controllers, Lynx Shunt VE.Can, and Skylla-series chargers, making it a versatile addition to complex energy setups. The sensor’s ring terminal design allows direct mounting to a battery terminal, ensuring rapid thermal response and stable readings.
Key Features
- Temperature-compensated charging adjusts voltage based on real-time battery temperature, improving charge efficiency and longevity
- Wide compatibility with MultiPlus, Quattro, Cerbo GX, Ekrano GX, Venus GX, VE.Can MPPTs, Lynx Shunt VE.Can, and Skylla chargers
- Rugged, compact design with an integrated ring terminal for secure battery post attachment and reliable thermal contact
- Extended temperature range from -20 °C to +70 °C, suitable for engine rooms, outdoor enclosures, and harsh climates
- Simple installation via ferrule-terminated conductors that plug directly into GX device or inverter/charger inputs
- Customisable cable length allows you to shorten or extend the lead to suit your installation layout
Why Temperature Sensing Matters
Battery chemistry is highly sensitive to temperature. Lead-acid batteries require voltage compensation of approximately -16 mV/°C per 12V cell to avoid overcharging in heat or undercharging in cold. Lithium batteries demand precise thermal limits to prevent charging below 0 °C, which can cause irreversible damage. The Victron Temperature Sensor provides the data your Victron system needs to automatically apply these corrections, safeguarding your investment and maximising usable capacity.
In systems without temperature sensing, chargers operate on fixed voltage setpoints. This can lead to chronic undercharging in winter, reducing available amp-hours, or accelerated grid corrosion and water loss in summer. By integrating this sensor, you eliminate that guesswork and let your Victron equipment dynamically adapt to environmental conditions.
Seamless Integration with Victron GX Devices
When connected to a Cerbo GX, Ekrano GX, or Venus GX, the temperature sensor appears as a data source in the VRM portal and on the GX Touch display. You can set up alarms, trigger relays, or adjust charging parameters based on temperature thresholds. This level of control is invaluable for unattended sites, marine vessels, and remote off-grid cabins where battery health directly impacts reliability.
Installation and Compatibility Notes
The sensor is not calibrated at the factory and carries an expected deviation of ±2 °C, which is sufficient for charge compensation and safety monitoring in most applications. It is not designed for prolonged exposure above 70 °C, so avoid mounting it directly on engine blocks or exhaust components. The cable can be shortened or extended using standard wiring practices; ensure connections are secure and protected from moisture.
This sensor is not compatible with the BMV-7X2 series battery monitors, which use a different sensing input. For those devices, please refer to the dedicated BMV temperature sensor accessory.
Applications
- Marine and RV house banks where ambient temperatures fluctuate widely
- Off-grid solar systems using Victron MultiPlus or Quattro inverter/chargers
- Telecom and industrial backup power requiring automated thermal management
- Lithium battery installations needing low-temperature charge protection
- VE.Can MPPT solar charge controllers for temperature-adjusted absorption and float voltages
Protect Your Power System with Precision
Add the Victron Temperature Sensor to your energy setup and enable your Victron equipment to make smarter, safer charging decisions. Whether you are commissioning a new off-grid system or retrofitting an existing installation, this sensor delivers the thermal insight needed to extend battery life and improve overall system reliability.

WARRANTY
Victron Energy Limited Warranty Policy
Direct Customers
Victron Energy provides the following warranty to any direct customer (OEM, distributor or dealer) in relation to any products that Victron Energy has directly sold to the direct customer. This warranty is not an end-user warranty between Victron Energy and an end-user, and end-users shall not have any rights or remedies under this limited warranty towards Victron Energy directly. The direct customer shall, in turn, ensure that the end-user is provided with a warranty identical to this warranty, subject to applicable local mandatory law.
End-Users
Victron Energy may also provide a warranty directly to end-users, in which case the below warranty conditions equally apply to such warranty. In that case, end-users shall claim their warranty at their place of purchase or through the original direct customer of Victron, which can be found through the support section on Victron’s website. Hence, the direct customer shall on behalf of Victron Energy deal with any warranty claims made under any warranty that Victron Energy may provide directly to end-users. This support section on Victron’s website will provide further guidance on the procedure for end-users to make a claim under this limited warranty.
If the end-user is a consumer – a natural person who is acting for purposes which are outside that person's trade, business, craft or profession – the following applies. The rights and remedies granted to the consumer under this limited warranty are without prejudice to the consumer’s statutory rights. Furthermore, the consumer is entitled by law to remedies from the seller free of charge in the event of a lack of conformity of the goods (such as repair, replacement, price reduction or rescission), which remedies are not affected by this limited warranty.
Warranty
Victron Energy warrants its products to be free from defects in workmanship and materials for a period of 5 years from the date of purchase by the original end-user, with a maximum of 66 months from the Victron Energy invoice date.
