Victron Energy Smart Battery Shunt - Battery Monitor (Bluetooth) - Victron Smart Shunt with Detailed in-app Insights - 6.5V-70V, 300 amp

I bought the Victron Energy Smart Battery Shunt to add Bluetooth monitoring to my battery power box, and so far it has worked really well. I haven’t noticed any interference or RFI issues, though I don’t have a precise way to test for it. I’m happy to have this separate smart shunt rather than relying on built-in Bluetooth on a LiFePO4 battery. The setup was straightforward, and the detailed in-app insights are very helpful for tracking battery health and usage. Potential Uses: Monitoring home-built battery power boxes Off-grid solar systems and battery banks RV, camper, or marine battery monitoring Ham radio or portable electronics power setups Tracking deep-cycle battery health and usage Measuring current, voltage, and state-of-charge in DIY projects Managing multiple 12V–70V battery systems Disclaimer: This review reflects my personal experience only and is not professional electrical or technical advice. Always follow proper safety procedures and consult a qualified professional for installation or use of high-capacity batteries and monitoring devices.

Victron solar equipment is high quality and this shunt is no exception. Very easy to install and the included cables are a plus. Integrates flawlessly into the Victron app and gives all the information about the usage and states of your batteries that you need. The only drawback, as others have stated, is the short range of the Bluetooth signal. But that seems to be the case with a lot of these type devices. I’m pleased with the device and the price was reasonable.

* Measurements are pretty accurate. * The app is handy, with lots of information and useful trend data. * Integration with other Victron equipment is very nice. * It has been working flawlessly for over a month now.

Although this shunt will work as a standalone monitor this is NOT its intended purpose. Victron system devices are meant to work together. When I bought this I was intending to use this as standalone using Bluetooth for monitoring. Like others have said, the Bluetooth is not great. Not only is the range very short but if you stay connected too long there will be frequent Bluetooth connection "losses". This is quoted because it's not just disconnected but when you try to reconnect the shunt will act as if it's still connected which the only remedy is to pull the small power wire. After a bit of learning more about Victron products, which are the best of the best, I've learned the ve.direct port is where all the magic happens. I already have a Victron SmartSolar 150/60Tr and now this shunt. I like to watch it CONSTANTLY and couldn't keep having to pull power on both the SmartSolar and the Shunt just to get it to continue working after Bluetooth fails. Also to note, when you pull the SmartShunt power to power cycle it it will lose it current SOC reading. It will fix itself once you hit Absorb and Float but that's not always helpful if you're already sitting as a low DOD. The missing magic box for monitoring everything, not just locally but also when away, is the CerboGX. This will allow you to connect the SmartSolar and SmartShunt via ve.direct then you can connect the CerboGX to either WIFI, for away monitoring, or connect to it via Bluetooth, for local monitoring, which seems to have a much more stable connection. Fortunately for me I have a Alcatel 4G router with ethernet port, which the CerboGX also has an ethernet port. Now I have the 4G router running off the LiFePO system and connected to the CerboGX so there's never downtime. The next step was setting up an account in the VRM portal which was insanely easy and now have SO much more details and trend graphs to monitor not only real time but MUCH more such as battery curve on discharge, solar voltage, solar amp, total amps used, battery charge cycles....the list is massive and has everything you could possibly want. Yes the CerboGX is a little costly, which caused much hesitation when initially choosing it, but after getting it and fully setting it up it has been WELL worth every single penny. If you're going to make the investment into the amazing Victron ecosystem it's best to do it the right way. You will not be disappointed and will only want to see just how much more amazing it can get....and Victron devices can expand further than your wildest imagination. I can't express enough just how much I initially wanted to go cheap but let me tell you....you will need to buy more components to any system and Victron makes this near dummy proof. Just read the manuals for each device carefully and don't go over any limits they set. That's all I have for you, happy solar harvesting!! My System: -10x Renogy 100w compact with their tilt brackets (5S2P) -Victron SmartSolar 150/60Tr (yes over-paneled to get to peak charge sooner) -Victron SmartShunt 500a -Victron CerboGX -2x Chins 12v300a (2P for 12v system/ gives me options to go 2S for 24v) -12v1200w Giandel (2400w surge for a few seconds) Considering 24v3000w Giandel and all I'd need to upgrade to a 24v system then many fuses and circuit breakers throughout I know my pictures have a wiring mess but this is only due to not knowing what more I was going to add/change in the system. Once I decide if I'm staying 12v or move to 24v, and get the 24v inverter(they're MUCH bigger but all I need for this change) then I will be changing fuses/breakers and bundling all wires to fit my usually OCD/Perfectionist tendencies. And yes that is a raspberry pi screen I'm using for direct monitor from the CerboGX haha I also included the VRM (Victron Remote Management) views from PC, 2 darker views, and the one from the mobile device app. Thought that might be helpful in understanding the value of the CerboGX and VRM (which a VRM account is free)

Worked like a charm! Used it to help troubleshoot a parasitic drain on my 2014 Honda Odyssey. Very handy for monitoring the Amp draw while inside the vehicle pulling fuses and disconnecting harnesses. Bluetooth range was a little better than I thought it would be. I could stand at a window in my house and monitor the shunt from about 30',LOS. This thing will be a great troubleshooting tool for any DIY individual.

This is used for a single lithium battery. The battery's BMS appeared to be accurate, but with more testing, it was too erratic on SOC. Reading the manual, the BMS can't detect low discharging and charging. I purchased and installed the Victron shunt so I could get accurate data. The installation was straightforward. If it won't be exposed to high moisture, I prefer this one. The IP65 version has all possibilities of sensor cables potted in. On this one, you only connect what you need and terminate wires to a neat length. I appreciate how much more accurate this is than the BMS. Areas for improvement are the speed the Bluetooth syncs. Opening any other Victron device and the Bluetooth needs to re-sync every time. Distance is also marginal, it should work in a bigger radius like other Bluetooth devices. For the price and simplicity, I am glad to have it for the times when battery data is critical.

I installed the Victron Energy Smart Battery Shunt to keep an eye on my boat’s starter battery, and honestly, I wish I had done it sooner. The Bluetooth monitoring works perfectly—I can now check my battery’s status from anywhere on the boat without doing the awkward “lean over the engine bay and pray” maneuver. The readings are accurate, the setup was simple, and it’s already prevented at least one “guess we’re not going anywhere today” moment. For fellow boaters who like reliable tech (and dislike being stranded at the dock looking confused), this thing is worth every penny. If my starter battery had feelings, I’m pretty sure it would thank me. Highly recommend—5 stars! 🌟🌟🌟🌟🌟

I've been upgrading the boat's front end electrical system including a 120 amp alternator, so I needed to upgrade from my 100 AMP Shunts. This thing is fabulous. (It's in the project box on the top right of the image). no more wiring loom going to a display. Along with the Victron shore power charger I can now see much of my electrical system performance right on my phone from the cockpit thanks to the bluetooth connection. Dead easy to install, I have it hooked up to my house bank, but it also can monitor my start battery. Makes diagnosis of problems much easier having all the data in my pocket anywhere on the boat. BT range is not huge but adequate. Can be blocked by the engine depending on where I stand. but the BT booster is an available option. Money well spent

Perfetto, molto semplice da installare se si ha manualità ovviamente. Gestione da app eccellente, mi raccomando seguire le istruzioni del manuale on line per i settaggi della batteria, se è al litio ci sono dei parametri da modificare, na li trovate nel manuale. Victron è sempre una sicurezza.

Le module enregistre 45 jours de données aux on ne peut accéder qu'en bluetooth depuis l'application. L'exportation est totalement verrouillée par Victron, il faut ajouter un Cerbo gx qui coûte 300€ et ne permet d'avoir les informations qu'à partir de son installation. Je n'en reviens pas

Pues está bien caro pero es funcional, te permite saber el estado de la batería así como la tendencia histórica de 6 meses hacia atras El único tema es que el tornillo está muy gordo y no entra el adaptador de mi bateria, ojo… esto no corta carga ni actúa como gestión de la batería, solo es para observación

El SmartShunt 300A 50 mV es un monitor muy recomendable si quieres un sistema limpio, confiable y conectado, ideal para paneles solares, baterías de litio/AGM/Lead en autocaravanas, embarcaciones o instalaciones independientes. No es perfecto para todos (especialmente para instalaciones grandes donde 300 A se queda corto o si necesitas pantalla integrada), pero en su segmento es difícil encontrar algo tan completo y sencillo de usar.
