Hi, do you manage to update the settings from the mobile app? so far with the mobile app I can only get a working main screen (the one that displays the SOC), but no luck with all the settings. I have 3x BMS, all behaves the same.No, I don’t have the same issue on my 4S 80A unit. I just successfully changed from 100Ah to 90Ah and back again.

I thought the reason was because mine is 4S, and requires different Windows application, so could have explained why the mobile app would not cope with the 4S, but I see you are talking about 4S.
So could you let me know how you do it? how do you input the code? Which version of the APP? are you on IOS or android?
