Review: Easy to install, no frills, works well - I got this to use on a secondary car that is left parked for potentially long periods of time. I have a solar powered battery maintainer hooked up to it but I also wanted to easily check on its state of charge just in case. The BM2 fills that purpose perfectly. Installation is simple. You just clip its wires to the respective battery terminals and secure the unit somewhere safe (I just zip tied it to the top mounting bracket of the battery). After installing the app, it detected the monitoring unit and started reporting the voltage automatically. You can set alerts and also offers start and charge tests. It does use Bluetooth, so range is limited (especially considering it has a metal hood covering it normally). YMMV. Worst case, you may have to walk close to the car to get a reading. But at least you don't have to pop the hood or mess with the battery. It does keep a history which it updates to your app next time it connects, so you won't lose data points. All in all, it does exactly what I need.
Review: Easy to install, easy to use, useful information. - Bought this here instead of Aliexpress bc its a similar price. Very simple to install and works immediately. Download the Battery Monitor BM2 app from the app store. You have to be in bluetooth range to get a reading. You can get a current reading, or charts that track voltage over time, and you can set notifications to let you know when the voltage drops to certain levels.
