I have been using this for a year to monitor a 36 volt 100 amp battery that I installed in a golf cart (a huge upgrade). It always connects right away and provides granular information at the cell level as well as cycle life, temperature, and charge rate. I can turn on and off the battery discharge and charge circuits separately. It has an advanced mode for changing parameters, which I have not used. Highly recommended.

Works. Works as expected, and reliably. And it's a nice pretty interface. My friend described it as a UI designed by a user. A casual user. It's great to monitor multiple batteries at one location. I do wish the buttons to toggle between batteries were just a little bigger (make them easier to hit when I'm accessing my android monitor remotely) For a more in-depth interface for the DIY, see Overkill Solar (BMS)

I am currently not very happy. The "BAT-BMS" app works one day, but not the next. Uninstalled the app and re-downloaded/re-installed it. Got the same result. Did another un-install and re-install - now the app will not connect to the battery at all. I need some customer service assistance. (using Samsung phone with Android 14) This is quite costly battery with built-in BMS and Bluetooth communication, um, minus the Bluetooth communication. I'd go 4 or 5 stars if the Bluetooth app worked
