Smart Battery Sense, Voltage and Temperature Sensor

Update (11/18/23): The VE app keeps historical data for 180 days, and will also generate graphs (e.g. voltage and temperature) [pics added]. Update (2/12/23): Current inventory of VE products: (2) 100V/50A, (2) 100V/30A, (1) 100V/20A, (1) SmartShunt IP67 (newer), (1) SmartShunt (older), (1) BatterySense. Best feature is the VE.Smart networking feature, which allows the components to work together to optimize charging of the battery bank. Summary: This review is for the Smart Battery Sense monitor, which is a bluetooth voltage and temperature monitoring device. This has voltage and temperature monitoring. Whereas the SmartShunt can measure current too, but lacks the temperature ( can be added with an extra sensor ). Current solar/PV system specs: 4kW of panels (most are 100W panels); 24-volt, 21kWh marine AGM battery bank; 3500W inverter; VE SmartSolar MPPT controllers: 20A (one), 30A (two), 50A (one); battery sense monitor (one). Observations: Currently have the battery monitor and two current shunts (one for battery, and one in energy monitor mode to see the current draw into the inverter). One of Victron's best features is the ability to network the controllers together, so that you don't over charge your batteries. I am running four (4) VE MPPT controllers, and 75% of the panels feed into those, but I have a few other test MPPT controllers as well, so having the capability for the VEs to stop charging (absorption and float) is very important to prevent over charging your batteries. Recommendation: If you're trying to determine if the Victron Energy family of components is worth the extra money, I would say yes, based on the ability to integrate different components (mppt, battery monitors [current, voltage]). If you have a simple system, and do not need bluetooth monitoring, there are other solar/PV controllers for less. Pros: VE iPhone/iPad app works well; VE networking. Cons: None for now. Conclusion: At $40, rating this 5-stars.

Bought this because it's victron and they are the best and recommended by many DIY installers and professionals. I bought this item for it's intended use and I can say 100% that it works as intended and super easy to setup. Because it's bluetooth there can be some weird connectivity issues but I don't blame this device I blame bluetooth because of how finicky it can be on different devices. Anyway, the value for the money and the accuracy which I compare to a Craftsman multimeter from 25+ years ago and it's right on point with the volt measurements which are graphed in real time. The one thing I don't like is there seems to be either no ability to zoom into the the time window if the peaks and valleys are low and high. I couldn't find a way to narrow down when my battery went from no draw to draw. I could see the valley but I couldn't see the peak even if pinching my fingers on the screen like I would have expected to work. All good, still give this a 5 stars because it's just awesome and so is the price.

great product, poor pairing instructions. after too many attempts at pairing as the app wanted a PUK code, i gave up an ordered a return. as i dearly needed this great invention, i sat down with a fresh cup of coffee and did not give up. finally i found the PUK code in blue box in tiny print. used it, and voila, i am paired and happy now. it works as indicated and as needed and great product for the price.

Easy to install and pairs quickly with the Victron app. It provides accurate battery voltage and temperature readings, helping the charge controller maintain my AGM battery safely.

Quite small device. Works as advertised for my limited application which is monitoring car battery. Installation was easy enough, but I had to guess on the app to download and Bluetooth connection because QR code was expired link and B/T pairing code was either missing or not clearly listed. Low/high voltage alert notifications would be nice to have. Seems well made, doesn't appear to be water or shock resistant.

If you do not have a BMS on your battery, this works surprisingly well and even has a video on how to connect. Good value, great product so far. I got mine stuffed between two Tesla modules. I will add a picture of what you’re trying to avoid as well and why this is important to have.

I do a lot of road trips, camping, photography gigs, and side work, which means my car basically doubles as a mobile charging station. I’m constantly running a laptop, charging drone batteries, camera batteries, my phone, and sometimes using a 400W inverter. While driving, no big deal. But parked? That load can drain a battery fast enough to become a real problem. I’ve had enough dead battery moments to finally invest in a small 200W solar setup with a Victron charge controller just to help keep things alive. The problem was my Victron controller is mounted in the rear of the vehicle near the inverter, while the battery is up front. That creates two major issues: Voltage drop between the controller/load and the actual battery Massive temperature differences My trunk might be sitting around 60°F while the battery under the hood is cooking at 120–130°F. As you can imagine, that makes accurate charging pretty difficult when the controller is reading conditions from the wrong place. Voltage and temp inaccuracies can absolutely lead to improper charging or overcharging. That’s where the Smart Battery Sense actually earns its keep. Once installed and tied into VE Smart Networking, the controller can finally read real battery voltage and temperature directly from the battery itself instead of making bad assumptions from the trunk. That alone made a huge difference. Charging stages like bulk and float are now handled much more accurately, and I’ve had far fewer concerns about overcharging due to bad temp compensation. For my use case, this solved a legitimate real-world problem. What I like: Accurate battery voltage reading directly at the source Proper temperature compensation where it actually matters Better charge stage control Easy integration with existing Victron gear Great for mobile/off-grid vehicle setups What I don’t like: There are cheaper Bluetooth battery monitors out there You’re definitely paying extra for the Victron ecosystem Historical data isn’t stored well in the app unless you reconnect to the device Data granularity drops off pretty quickly over time Would really like to see controller voltage and Smart Sense voltage side-by-side for easier voltage drop monitoring, instead if you are in the charge controller you only see charge controller voltage, but you do see temp at least. So while the hardware itself works very well, the software side could definitely use improvement. Overall: If you’re running a Victron setup and have longer cable runs, temperature differences, or mobile power demands, this thing absolutely improves charging accuracy and battery protection. It’s overpriced for what it is, but it solves real problems and integrates well enough to justify it if you’re already invested in Victron. Not perfect, but for serious use, it’s been worth it.

Easy to install and allows me to read the battery temperature and volts from the Victron MPPT app. Great quality.

Victron is a quality product and easy to connect, configure and integrate into other Victron products.

Obligatoire si vous avez plusieurs mppt relié en réseau. Normalement, le fait d'être en réseau, les mppt devraient "discuter entre eux" et s'ajuster (voltage batterie, état de charge). Et bien non, il faut ce petit boîtier pour les synchroniser correctement. Victron pousse à la consommation ! En dehors de ça, Victron reste à mon avis le meilleur en terme de production, et son application n'a pas d'équivalent par son ergonomie et la qualité du suivi solaire. Une "babiole" chère pour ce qu'elle est mais malheureusement indispensable pour une recharge solaire cohérente.

Arrived on time and packaged very well. Fitted and working well. Second one purchased to accommodate further additional solar panels.

Lätt att ansluta till solcellsladdaren och mobilappen. Gör det den ska.

Fácil instalación e integración en la red. Recomendable
