Review: Easy to understand instructions - 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!!!!
Review: Accurate and dependable - 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.

## Features

- 1% Accuracy Measurement: Shunt-type battery monitor design provides much more accurate real-time voltage and current draw measurement.
- Protect the batteries: With High and low capacity alarm functions, our battery tester with shunt will alarm, and backlight and voltage value will flash simultaneously to protect the batteries from getting over-discharged.
- Fit for all battery: The energy monitor is compatible with various battery types, including Lead Acid (AGM, GEL), Lithium Iron Phosphate, Lithium-ion, Nickel-metal hybrid. 12V battery monitor compatible with batteries operating at 12 volts, 24 volts, and 48 volts.
- Easy To read: Renogy battery monitor displays multiple electronic parameters, including Voltage, Current, Consumed Power, Battery Capacity, and battery degradation rate with a customized brightness high-definition Backlight Display.
- Easy to Install: Transparent shunt holder makes the renogy lithium battery monitor easier to mount the shunt. And the 20ft Shielded cable allows you to monitor the battery status from a distance.

## 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.

### ⭐⭐⭐⭐⭐ Love these battery monitors!
*by J***E on September 5, 2025*

I have 2 of these. Simple to set up: 1. Attach the shunt’s -B end to the battery’s negative terminal 2. 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.
