I have four of these devices. So nice to monitor battery charge level without having to directly access the battery. Simple to install and a real timesaver, especially when you have multiple batteries in different vehicles to monitor.

Easy to install and use. Had it a week. So far, so good. Ordered another one. Check your battery while you are having your coffee. No last-minute Suprise! Works at least 40 feet for me. Your results may vary! The history feature is nice. Could show a coming failure, or be useful to an Auto Tech when a problem develops.

Great product. I tried two other monitors for my Lithium 12v 100 ah trolling motor battery. I trusted neither one since it seemed to always show 100% after hours of use. This monitor recorded power/percentage drop while using and power increase while charging and alerted me when charged to 100%. This is simple to install, just two connectors to the battery. Range is really goid. Boat is in garage and it connects anywhere on the same level in the house. Love the built in alarms. Great price to have the ability to check the battery level on your phone. Getting second one for the Fish-finder battery.

Keeping a check on the 12v battery is especially important with electric vehicles. Very easy to install. Paired immediately with my Ioniq 5. I particularly like the graph showing voltage history and the intervals when the car has charged the 12v. Has settings for lead acid, AGM, and lithium. Seems to read consistently about .2v lower than my multi-tester. Recommended so far. Don't know how long it will function.

I don't write many reviews but I liked this so much I wanted to recommend it. It installed very easily on my 2007 Silverado. After downloading the app, it paired right away with the unit. I was impressed with the app and its display. You see battery voltage at rest, when charging and during cranking the engine. I learned that the little solar panel on my dash was not keeping the battery fully charged so I went with a larger panel that does the job. For the price, this is an amazing tool. The range is limited - but quite good considering it's under the hood. I can connect to it from inside my home if I go near a window that's close to the truck.

besides the weak blue tooth signal, it worked fine for nearly 3 months. Now it wont connect at all. Waste of $30.00When it was working you had to get within 10 feet of the car to get a signal. Was hoping I could check it inside the house.Well, I won't be buying another, I will remove it from the car and toss it in the trash with a lot of things I get from Amazon.

I wasn't expecting much, but this does exactly what I need. I'm monitoring for an elusive intermittent parasitic drain, and this device keeps a detailed log of battery voltage status to send to my phone (iPhone 13). The Battery Monitor BM2 app from the App Store (required to use the device) connects via Bluetooth, and I can get a connection from inside my house to the vehicle in the driveway, about 20 feet away. Bonus is that the device keeps a log that it uploads to the phone when connected, so you don't need to stay constantly connected to get good info - just connect when it's convenient, and the most recent data will upload. I haven't yet found my vehicle's parasitic drain problem, but at least I now have a way to know when it is happening (other than discovering a dead battery in the morning). Again, note that the device does absolutely nothing by itself - you have to use the BM2 app on a phone along with it to extract information. By the way, if you double-tap the voltage graph in the app, it goes to a screen where you can view 1 day, 7 day, and 14 day data. All good stuff, and works much better than I hoped for the low price.

I’m impressed with this easy-to-use battery monitor. Just connect it to your battery, download and install the app, pair with Bluetooth and you’re ready to go! As long as you’re near your vehicle (or whatever you’re monitoring) it will auto connect and download the saved data when the app is launched. It will store up to 30 days of measurements. Since the data is transferred to your device, it’s designed to be used with only one phone or tablet otherwise the data will be scattered across devices. It captures the battery voltage once a minute allowing you to view charge and discharge profiles. I’m using one in my car and one on my 12v solar system.

Works great for constant monitoring of your state of car battery. Used it on my Hyundai Kona Electric.

Sensible, bonne longueur de fil, enregistre bien. Attention aux fils : ne surtout pas les modifier (y compris la cosse aluminium) car ils sont double, plats et en aluminium, donc à priori fragiles s'ils sont mal manipulés. Sur diesel, déclenche sur les bougies de préchauffage et très peu sur le réel démarrage du moteur. Dommage. A placer du meilleur côté de la batterie pour conserver une transmission bluetooth max.

A very simple and low cost way to monitor a battery use. Highly recommended.I have installed it in my campervan on the domestic battery. It gives me a plot of the voltage over the last 30 days whenever I connect my phone by bluetooth. From that it is easy to see the state of charge both when in storage over winter and in active use the rest of the year.I've used various amp counting battery monitors before on boats - but nothing as simple and cheap and easy to install as this. And sometimes simple is better.My van has a voltage gauge on the battery but this is both more accurate and gives me how the voltage has changed over the last few days. The iphone app works perfectly for this. I've had no problems with this app. It asks for permission to use bluetooth as it has to - so no what sure is meant by asking for "scary" permissions. It just does the job.
