500A Battery Monitor with Shunt, High and Low Voltage Programmable Alarm, Range 10V-120V up to 500A, 20ft Shielded Cable, Compatible 12V Lithium Sealed, Gel, Flooded Batteries,Black

Work fine in the application I need it for

Just finished installation in our RV. Would suggest Renogy consider a WiFi solution for remote access to monitor your batteries remotely. Ours is in storage many months and would like to have the convenience factor! Other than that running the monitor wire took the majority of time, just because it’s labor intensive! Installation was straightforward and a piece of cake…not only that but it worked the first time!!!!

Works great for me applications, boat and rv with this you control your battery power accurate, what is going out, and what is coming in

What did I like ? - the fact that everything you need comes in the kit. Wire(s), shunt, gauge just plug and play. It’s easy, then it all comes alive. Great ! 👍😊

This meter is much more accurate than my Bluetooth app that came with EG4 WP 48V-100Ah battery, which only updates every 5 seconds and doesn’t tell you that they “hold back15% of the battery capacity. It’s got variable illumination modes and every metric is configurable…though it’s a little too easy to hold the up arrow and reset battery meter in the middle of your cycle. The other reviews are correct that the + wire to the battery is tiny and the hole in the shunt seems tiny-er…it will eventually fit if you have patience and make sure the set screw is backed ALL THE WAY OUT (keeeeep turning). It’s best to do this part first, before you mount everything so you can get to, and still see, the tine hole. Also, the posts on the 500Amp version are enormous so get ready to buy some huge ring terminals to fit as all load has to pull through the shunt so you’ll want to combine several load wires per connector. Also, they don’t tell you but you’ll need some big power wire as it’s not included (see pics-I had an old winch power wire that I cut to fit). I would definitely purchase again.
