The voltage reading is accurate and gives a much better idea of battery health compared to the stock bar indicator. The blue display looks clean and matches well with modern setups. Installation is simple (just 2 wires), but make sure you connect it to a switched power source (key ON). If you hook it directly to constant power, the screen will stay on and drain your batteries over time. Also note: if you’re replacing a factory meter, some of those wires may be part of other circuits (like lights), so double check before disconnecting anything. Overall, solid upgrade and very useful for diagnosing battery performance under load. Review: Instructions are a bit confusing - I didn't find the "advanced" menus, even after multiple attempts, but I didn't see them as offering anything that useful either, as I just wanted a display of the battery state for my kids powerwheel when I upgraded it to use a 40V battery, which for that, it does a splendid job of. The display is clear, easy to read, and shows what I want to know. %, Voltage, and a "1-6" segment display of battery life. So I can really easily tell at a glance how close my kid is to killing the battery. (So far, VERY FAR...) ## Features - 3 in 1 battery voltage meter - With a switched function button to choose the battery capacity, real-time voltage or turn off; New alarm function, when the battery capacity is lower 20%, the screen display will flash to alarm.(Note: package only include 1 battery meter!) - Universial battery status monitor - wide working voltage input range DC 12V-84V.Can be automatically detect to the accurate capacity according to the battery voltage. - Suitable for various battery types - fits to 12V/24V/36V/48V/60V/72V/84V lead acid battery, Ternary Lithium battery, Polymer lithium-ion battery, 3-28 series Lithium ion battery, Storage battery, Water battery and 4-28 series Lithium Iron Phosphate batteries, etc - Sensitive LCD digital display - the small battery voltage reader with a PVC waterproof screen protector, clear and bright green backlight LCD display from any angle; Low working power consumption(5mA max), in additional there's a turn off button for it. - Multifunctional application - suitable for golf cart, RV, marine, boat, club car, motorcycle, car, bike, ebike, scooter, truck, vehicle, jet ski, forklift ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07V2KMQGQ | | Best Sellers Rank | #79,084 in Automotive ( See Top 100 in Automotive ) #88 in Battery Testers | | Brand | Proshopping | | Brand Name | Proshopping | | Color | Green | | Compatible Devices | Golf cart, RV, marine, boat, club car, motorcycle, car, bike, ebike, scooter, truck, vehicle, jet ski, forklift | | Customer Reviews | 4.2 out of 5 stars 2,214 Reviews | | Item Weight | 20 g | | Manufacturer | Proshopping | | Measurement Type | Voltmeter | | Min.

Step 1: be sure to put the meter into the setup mode. 1. disconnect the power 2. holding the setting button (on the back) 3. keep hold on setting button and connect the power supply at the same time 4. no holding the setting button any more, you will get into the setup mode. Step 2: press the setting button (on the back) to to select your battery type. "F" for lithium iron battery Step 3:press the function button (on the front) to choose the how many cells your battery pack have. Here we choose 4. Step 4: disconnect the power. Setup information is kept automatically. Finish. Any questions please let us know. **Q: Need setting advice to measure battery performance, using three batteries in parallel. two are 14 cell egos, lithium ion, and one is 16s iron.** A: I used this in the golf cart golf cart batteries are in series but it would probably measure it it’s fairly inexpensive there’s a button you press on it for the voltage you want to measure **Q: My RV battery is in a case; i do i have to mount this unit inside the case?** A: Dear customer, No, it don't have to mount the meter inside the case. Just make sure, the positive wire of the meter must be connected to the positive pole of the battery, and the negative wire of the meter must be connected to the negative pole of the battery. You can put it in where you want. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Accurate, clean upgrade — just wire it correctly *by C***Z on March 31, 2026* Installed this on my golf cart to replace the factory battery gauge and it works great.

So I can really easily tell at a glance how close my kid is to killing the battery. (So far, VERY FAR...) ### ⭐⭐⭐⭐ Inaccurate but usable with caveats *by C***K on June 20, 2025* 6mA current draw at 12V, <1mA if turned off/after 10s auto-off. Doesn't appear to really use more or less current for backlight, however. Percent reading vs Voltage for AGM/SLA seems off (inaccurate), depending on the source that you use for the curve. 13.03V input reads as 100%, 11.9V reads as 56%, 11.1V reads as 26%. Formulas I've derived off of some SLA battery data sheets show that 12.85V should be 100%, 11.9V should read 40%, and 11.1V should be about 0% capacity. So, it generally overrates the remaining capacity. 11.1V should be a totally flat battery, not 26% left. Still, it's usable if you take that into account. Each device is probably different due to "quality control" being fairly poor on stuff like this. Just make a quick chart or something. I'll just say 50% capacity is actually when it reads as 62%, and 50% capacity is often when a person should consider charging a battery to prevent damage. Display is relatively bright for 6mA and is clear. Included cable is short but uses a standard plug, or can be extended by soldering onto the wires. ## Frequently Bought Together - DC 12V 24V 36V 48V 72V Battery Meter, Battery Capacity Voltage Monitor Gauge Indicator, Lead-Acid&Lithium ion Battery Tester, for Golf Cart RV Marine Boat Club Car Motorcycle - with Alarm, Green - DC 12V 24V 36V 48V 60V 72V 84V Golf Cart Battery Meter with Alarm, Front Setting and Switch Key Battery Capacity Voltage Indicator Gauge Acid and Lithium ion Indicator(Blue) - IPX7 Waterproof Battery Monitor with Bracket 7-100V,12v 24v 36v 48v 60v 72v Digital Display Battery Capacity Remaining Capacity Percentage Tester with Buzzer Alarm and Temperature --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/146477651-dc-12v-24v-36v-48v-72v-battery-meter-capacity-voltage](https://www.desertcart.is/products/146477651-dc-12v-24v-36v-48v-72v-battery-meter-capacity-voltage) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-08-19*
