Victron Energy SmartShunt 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!

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.

15 minute install on class C with dual AGM group 24 battery bank. Much better that idiot lights that just show a very rough estimate. Easy to program. There is an idle current draw that a switch can be put on the 12 volts+ connection that is fused for storage. Idle current draw seems much larger than specifications.I set my dual parallel batteries at 180 amps rather than 200. Then set max discharge to 50%. Thus setting will offer more deep discharge protection to keep the max above 50%.After install I tested loads and unit appears accurate. I think all RV’s need this shunt. The cheap idiot lights on RV’s offer next to no information.The app was easy to set up and use.

I use a Victron shunt on all of my installations even though some of my server batteries have a built in system. Honestly, the real benefit is the ability to log over time and compare accuracy of the battery data. 300A shunts use the 5/16 bolt and 500A use the 3/8 inch bolts. I have switched to 300A since lets be honest, how many folks are pulling 500A?

This is a very nice way to track your house battery condition and show you where your charge is coming from. Very cost effective tool.

I wanted to give this shunt 5 stars, but the bluetooth range is not good. And the mid point is way off. My battery's have a bluetooth bms, and both battery's were within 1-2 % of each other. And the shunt was telling me 30 - 40% of each other. I really like victron product's but this thing really sinks.

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.

Got this to get an accurate read on my trolling motor battery. Seem to be accurate. I also have a Victron charger and it uses the same app. That is a nice feature, one app for two devices.
