Victron EnergySmartShunt Battery Monitor (Bluetooth) - Victron Smart Shunt - 6.5V-70V, 300 amp

Readability:The Victron app is easy to use - put it on your phone and it will instantly tell you the true SOC of your battery. Accuracy:It's well known that the only truly accurate way to get a true state of charge in a Li battery is with a shunt, and this provides that informationEase of installation:Couldn't be simpler - put it on a short cable going to your batt's neg post and then out to the negative of whatever fused panel situation you have in your rig or boat. The shunt becomes your new negative post - nothing else goes on the actual battery neg, ever.

As usual, Victron continues to provide exceptional quality, fit, finish and utility.Installation is a simple, straightforward process that requires only one additional short cable of the proper gauge for your setup.The included positive wire and secondary positive (for monitoring a second battery bank or midway point) have built-in fuses.One note - the bolts on this require 5/16" or 3/8" wire lugs on the wires from the negative battery terminal and to connect the load or bus block.The shunt itself is very sturdy, and designed for easy mounting in a small space near your battery.It also networks wirelessly with other Victron Smart controllers and other products over Bluetooth to allow them to share information, via the VictronConnect app.A few minutes of reading is all that's necessary to input the battery information and other parameters via the app, and before you know it you're up and running with detailed information that assists greatly with fine tuning your system.You may, like me, find yourself wondering how you ever got by without this addition to your solar power system. I put it off, questioning whether I really needed this. From now on, I'll have one of these on every system I install!

This product is the best investment I have done with my battery. I have a 100 ah LiFePO4 battery, and this thing keeps monitoring what I have consumed and when I charge it, how much is being charged. I strongly recommend this, before I was using a cheap shunt, that was not accurate. This one is excellent, and what really matters is that you can tell how much juice is left in the battery at any time, and the software will tell you, depending on your consumption how many hours you can run it at that consumption rate.

Is expensive but it is Worth the price! The best for measuring a lifepo4 battery capacity, great functions. And it is compatible, purchasing another expensive cable, with solar assistant

Great quality, easy installation, good instructions and blue tooth. I am using it as the only eviction device in my setup. Works great

The product arrived but it took me a while to figure out that the reason it wasn't working is because the fuse in the lead was defective. I switched the red leads and then it works fine. I am reaching out to their support team to ask for a replacement fuse for this because if the current one goes then I have none. And am open to improving the rating once this gets settled. I think this product should have also come with the VE.Direct cable instead of charging 10x the product cost as an add-on afterward.

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.

Wanted a solution to monitor my lithium batteries on my boat more effectively. This was the perfect solution! It was easy to install, reasonably priced, and gives me effective real time data on the performance and health of my Dakota lithiums.
