You're monitoring a battery without temperature data, so charging relies on assumptions. This sensor measures battery temperature and feeds it to compatible Victron monitors, enabling temperature-based charging so behavior reflects conditions.
A lot of systems already have a monitor in place, but they're still missing direct battery temperature at the source. This sensor plugs that gap by measuring main battery temperature through compatible Victron battery monitors, including the BMV-702, BMV-712, SmartShunt, and VE.Bus Smart Dongle. Instead of relying on assumptions about what's happening inside the battery compartment, you get temperature data from the battery itself, so the system can show what the battery is actually dealing with during daily use.
Charging gets harder to dial in when battery temperature swings with the weather or changes inside an enclosed compartment. This sensor supports charging optimization using temperature-based data, so the monitor can factor in real battery temperature instead of a fixed guess. In practice, that gives you charging behavior tied to actual conditions at the battery rather than broad assumptions from the rest of the system.
Without temperature feedback, it's easy to miss a battery that's running hotter or colder than expected until you start chasing odd system behavior. This sensor enables configurable high and low battery temperature alarms through supported Victron monitors, so you can set limits around the range you want to watch. Once it's installed, the system can flag a temperature issue while you're monitoring the setup instead of leaving you to spot it after the fact.
Battery compartments don't always leave you a clean path from the monitor to the battery, and that can turn a simple add-on into a wiring problem. This sensor gives you installation flexibility with an extendable cable length when proper conductor sizing is maintained, so you can route it where the system needs it without changing the whole setup. That gives you a cleaner install in real battery locations where the monitor and battery aren't sitting right next to each other.

Hi everybody, Andy here with etrailer. Let's take a quick look at this Victron energy battery temperature sensor. Now this is a battery temperature sensor that's gonna work with certain Victron battery monitors, and its job is simple, but it's important. It's gonna measure the actual temperature of your battery and send that information to your monitor. So why does that matter Well, because battery performance and charging behavior change with temperature, so by knowing the battery's temperature, the system can give you more accurate battery readings and help charging equipment operate more correctly and safely, especially in hot or cold environments. So this sensor is commonly used with Victron monitors like the BMB-702, and the BMV-712 and the SmartShunt.
It connects through the monitor's battery, the monitor's auxiliary input, which means that input gets used for temperature data instead of other optional measurements like auxiliary voltage. Physically, it's a small sensor that attaches directly to the battery, and it typically comes with the lead, as you can see here. that includes inline fuse for protection, as you can see there. So once installed, it's gonna work automatically. There's no ongoing adjustment or interaction required.
Now, if you have any other questions about this sensor or anything else that we have here at etrailer, don't hesitate to reach out. We wanna make sure that you're getting exactly what you need. Well, again, my name is Andy. Thank you for joining me.
Fast shipping worked great
