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

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!

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.

IT has been operational for about a week now. Very accurate and essential tool for monitoring energy in and out of the battery. Used for a small standalone off-grid electric system with both AC (Victron 24 2000 va inverter) and 3 other DC load circuits. The bluetooth range is rather limited, about 12 feet.

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.

Works well, super easy to install. Graph recording is super helpful, and layout is fantastic. Bluetooth range, is beyond abysmal. It's so bad it might as well just put an amp meter there and not have to spend the time to connect.

Seems to work well on a 200Ah lithium battery. I agree with others that the bluetooth signal is very weak; have to be within about 40' line of sight and no obstructions to connect.

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

Works perfectly. Very satisfied. Easy to install. Good value. Exactly what I needed.
