Review: Good Battery Monitor - Very happy with it's performance! Would buy it again.
Review: So much better than the others I had! BUY THIS ONE! - 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 powered Love 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!)

## Questions & Answers

**Q: Is there a purpose to having both this and the Bluetooth module?**
A: I have the bluetooth from the solar controller. I also have this renogy battery monitor.  because the battery monitor is so much more accurate the bluetooth module ( really only serves as a good approximate 'indicator')  it does show the voltage and amp input from the solar panels and you get to view this on yr phone which is i guess 'interesting'. But really unless the information is completely accurate it is difficult to actually say it is worth worrying about really.

**Q: Can this monitor a 1200ah system?**
A: Yes you can enter your amp hr. Upto 9999

**Q: Rv has 2x12v bats in parll. bat1+ feeds 12v bus; bat2- feeds gnd. invrtr + slr chrgr attch to these posts. hw to wire gge for both bus & invrtr cts?**
A: This Renogy Battery monitor is coming with its shunt that most be connected to the negative cable of your two batteries in parallel. No matter how many different loads you are connecting to the positive your Batteries monitor shunt should connect to the negative cable. So, you disconnect the negative cable from the battery and inserts in series the shunt, then the portion negative cable to ground will be be connected from the second post point of the shunt( - load). Try to follow the wiring diagram provided.

**Q: Why is this 80? Seems like there are other ones for half the price. Any advantage of having this one?**
A: It seems you haven't took in all the facts. It includes an excellent shunt, well designed, fully thought out. While 80 might seen high to you, some cost much more. I paid 94 and am very happy. A word of advice. What you read on this device will not match any display on your controller. This will seem confusing. It is tracking your batteries, where your controller is tracking a mix of solar in, loads out, battery in, and battery out. Take the time to understand the nuances, and trust this tool. It is excellent.

### ⭐⭐⭐⭐⭐ Easy to understand instructions
*by C***. on November 22, 2025*

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!!!!
