It was professionally packaged and is of good quality. My application is the off-grid power source for my well. The input is 860-Watt peak solar array, output through the batteries to a 3000-Watt, 230 Volt AC inverter to power my well pump. The on-time duty cycle of the pump is low. Follow the instructions and connect both the C- charge source and the P- Output (load) to the Shunt sampler P- terminal. Also "Teach" your battery bank capacity to the monitor per the instructions. Keep in mind that the Amp reading and Watt reading is the Net current and Net power. Example; you may have 10 Amps coming from the charge source, but a 4 Amp load so the Battery monitor will read +6 Amps going to the battery. With no charge source current (solar panels in the dark) the meter will read -4 Amps for the same load. Think of it as the old center 0 analog Amp meter, but with much more useful tracking of the Net Amp-hours going in and out and percent of remaining capacity of the battery bank. It should be used with a quality charge controller that has an Amp meter so you can distinguish the total solar power output. My charge controller cable going to the sampler P- terminal is AWG 4 because my solar array is capable of 52 Amps peak output. My load cable going between the sampler P- terminal and the 3000-Watt inverter is AWG 2/0 because it can draw over 250 Amps. My only complaint is the mounting of the meter itself. It is designed to be snapped into a panel rectangular cutout dashboard rather than surface mounted on a wall. I Macgyvered a mounting bracket for it from what I had available. Overall, it is good value, good quality, accurate and reliable. Review: Works great and provides the information that I need. - I have been running this monitor in my RV for over a year now and it continues to work great. I mounted the shunt on the wall behind the batteries and there was enough cable to install the display above my circuit breaker box about twelve feet away. It looks like it came from the factory that way. Installation was straight forward. I have 228 Amp Hours of batteries and it is so easy to monitor them now. I like the provided metrics, the +/- indicator of how many amps are being charged or drained, how many watts are being consumed, the estimated time (hours:mins) remaining until zero, and the battery percentage. Since I'm running lead-acid batteries I have to keep them above 50%. ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07RP5B5P7 | | Best Sellers Rank | #6,536 in Automotive ( See Top 100 in Automotive ) #10 in Battery Testers | | Brand | Renogy | | Brand Name | Renogy | | Color | Black | | Customer Reviews | 4.4 out of 5 stars 2,595 Reviews | | Global Trade Identification Number | 00810009712206 | | Included Components | 1*LCD Interface, 1*500A Shunt/Sampler, 1*Shielded Wire, 1*B+ Wire,1*Shunt Holder | | Item Dimensions | 3.9 x 2.4 x 0.7 inches | | Item Type Name | Compatible with 12V Lithium Sealed, Gel, Flooded Batteries | | Item Weight | 75 g | | Item dimensions L x W x H | 3.9 x 2.4 x 0.7 inches | | Lower Temperature Rating | 14 Β°F | | Manufacturer | Renogy | | Maximum Operating Voltage | 120 volts | | Measurement Type | Ammeter, Voltmeter | | Minimum Operating Voltage | 10 volts | | Model | RBM500-G1 | | Part Number | RBM500-G1 | | Power Source | Battery Powered | | Specification Met | RoHS | | Style | Voltage Tester | | Style Name | Voltage Tester | | UPC | 810009712206 | | Unit Count | 1 Count | | Upper Temperature Rating | 140 Β°F | | Warranty Description | 1-year material and workmanship warranty | ## Product Details - **Brand:** Renogy - **Color:** Black - **Item Weight:** 75 g - **Power Source:** Battery Powered - **Style:** Voltage Tester ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/61qo1E+V7KL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Overall, it is good value, good quality, accurate and reliable. *by J***. on May 15, 2026* The Renogy 500A Battery Monitor with Shunt was received in good condition.

Adding this meter gave me actually useful info. It’s awesome how it seamlessly switches between time remaining (when on discharge) to time until full (when charging). It’s been flawless. I 3D printed a small housing for it and it looks right home in my RV. The shunt was easy to install and can handle big current without adding resistance. I looked at cheaper options and they came with bad shunts, small screws/lugs, and got poor reviews for reliability. Don’t do it- just get the Renogy. ## Frequently Bought Together - 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 - TKDMR 10pcs 1/0 AWG-3/8 Battery Lugs,Heavy Duty Wire Lugs,Ring Terminals,Battery Cable Ends,0 Guage terminals,Battery Terminal Connectors with 10pcs 3:1 Heat Shrink Tubing - Renogy 2000W Pure Sine Wave Inverter 12V DC to 120V AC Converter for Home, RV, Truck, Off-Grid Solar Power Inverter 12V to 110V with Built-in 5V/2.1A USB / Hardwire Port, Remote Controller --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/154101597-500a-battery-monitor-with-shunt-high-and-low-voltage-programmable](https://www.desertcart.tn/products/154101597-500a-battery-monitor-with-shunt-high-and-low-voltage-programmable) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-03*
