For a free and basic BMS reporting application this is an acceptable application. Everything works and it provides basic statistics and is easy to understand and use. Documentation is basically nonexistent but given how simple the provided information is that is okay. Battery doesn’t always auto connect which is frustrating and I would like to see specific documentation as to setup and maintenance of batteries with compatible BMS functionality.

Please if somebody can help me out I cannot turn off or on my battery I was working five for a couple weeks now it just doesn't work I cannot turn off on I reinstalled the app couple times download it again and still the same issue show me the screen only for how much is charged but I won't turn on

Battery disconnects and doesn’t reconnect automatically. I like that, it keeps the power from being wasted on a BT connection.But why does the app open on the data page when you have to go to the connection page every time? Start on the connection page, then have it go to the data page.

Installed app on my iPhone 11 using latest iOS. Connected easily to my new Chins 48V 100Ah LiFePO4 “smart” battery, giving plenty of useful data, except that 5 of the 16 cells don’t display. (I tried the app on an iPad and all cells appear there). I emailed Chins about this and they replied promptly, saying they will look into this glitch.
