Renogy 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

this works great, i have 2 litime 230 ah battery's that have bluetooth, but you have t switch back and fourth to see what is going on, and they wont show anything under amps. this thing shows everything that is coming in or leaving. great tool for our boondocking

Works great easy to set up very nice to see what percent your batteries are at so far works great I have it hooked up to 2 ruixu lithi2-16 and it runs accurate to the display on the batteries and has a long enough cord so I could mount it in a visible location

I bought two of these for my boat and completely satisfied with them. They were fairly straightforward to install and have worked as described. The instructions were clear and easy to follow.

It worked alright, had it in a solar powered Golf cart. Its dead now, but the Texas sun kills everything.

The digital display screen is bright and readable. It's nice having the display in the rv coach to monitor the lithium batteries.

If you throw your money straight in the garbage can now you will at least save yourself the time and heart break of getting Renogy's buggy hardware/software to work only to have it fail every time you need it most. I'm not a pro RV converter but I have split my career between troubleshooting IT and Electrical systems and there is nothing about this technology that should be over my head.That said all the Renogy equipment I have purchased for my van build has been a nightmare that I don't have the time to fully detail. I have had reliability issues with my Renogy charge controller, multiple models of system monitors and an inverter and my panels have never been able to deliver more than 65% of their claimed rating even in the most ideal conditions.The constantly updating app has never fully worked even once and is clearly prioritized to collect personal data so if your system isn't behaving when your off the grid and it logs you out forget about using it to troubleshoot. The Bluetooth connectivity is a joke. The latest kick in the **** is that my charge controller failed when my van was parked for a month and now my $1200 battery is shot. That was the one non-Renogy component in my system.I had several friends with less technical experience tell me to just get a packaged solution like a Jackery or Ankor and I said naaah, I got this. After several thousand dollars, dozens of hours, and multiple partially ruined weekend trips I am eating my words.

Purchased this along with a new 2000W inverter and a smart hub for a camper electrical system upgrade. Now I can run A/C (for a little while), or a microwave, or small things like a laptop in the camper. The data from the shunt is helpful and integrates well with the hub or directly to your phone with Bluetooth. Renogy products have impressed me so far.

This is what every solar generator needs.
