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

Easy set up, no frills, monochrome screen. Works great and seems accurate. Nice to get something that just does the job and isn't trying to be a rock concert about it...

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

Just a backgroud. I had purchase 2 of the L**X brand, the full color version. Looked great. But the menu was no longer the one that they have now. It seems there are 3 versions and no one has the one I had. They never tid work based on extensive instructions from the selle.FAST FORWARD TO RENOGY! EXCELLENT ALL THE WAY AROUND!For the two I had, I swapped out thee shunt, did a little rewirie to clean up the backup battery setup, connecte dthe Renogy and it powered on. The default Ah is 100 and that's what I have. All set up with nothing else to do! Aftre about 15 hours of work on the others with no results, I am AMAZED. Now THIS is how you do it.I did the soemwhat more difficult replacement in my ham radio portable kit (inside a rack-mount case, where the shelves have to be removed). Replacing the shunt and everything else wasn't as easy, that not due to Renogy; my setup is compact and under layers and it is hard to get to things inside. But for making the mounting plate to replace the smaller piece I had, I just plugged in tin and there it was! Set the capacity (will need to redo after a full charge and there, right in the menu was an easy setting for the Ah, which took moments.Everything works as it is supposed to and all very easy. Almost sets itself up once installed and poweredLove my Renogy suitcase panels and these are completely excellent.The screen, when off, is a dim grayscale, but draws no current at all somehow. Looks fine in the light. The green screen wout be nice in high contrast plack and white or full color, but I only mention this to my low vision. I can do without the nice screen for this easy setup and bigger screen.BUY THS IS YOU NEED A MOINITOR (OR TWO OR THREEE!)

This battery monitor is a value for the money. It is simple, but gets the job done. My favorite features is the it includes a 500a shunt and a long signal wire. This makes the installation easy. Other great features is the display showing voltage, amp hours remaining, amps going in/out and total time to full charge/discharge. The screen has multiple levels of brightness and pulses when it's charging. The only thing lacking is connectivity to other renogy devices and apps. Overall I would recommend this compared to more expensive units such as the balmar battery monitor (which I have as well)

I use it on my home battery backup system. It works great and very accurate.

I have 2 of these. Simple to set up:1. Attach the shunt’s -B end to the battery’s negative terminal2. Attach the red wire to the battery’s positive terminal and the wiring block on the shunt.3. Connect your load to the battery’s positive terminal and to the -P terminal on the shunt.4. Plug in the display.5. Change the parameters in the display to match your battery’s specifications.I designed and 3D printed a stand for the display so I can put it wherever I want instead of having to permanently mount it.

Very simple to connect into your solar system, nice feature to have it shows the condition of the battery

Pleasantly surprised. Installation was easy. Only improvement would be a mechanical mount (screw) for the display
