BM6

The state of charge for my battery displayed 2 to 3% when fully charged. To fix this: tap in the upper left: three lines icon, tap the: serial number text, tap: custom battery. Adjust the data below to the manufacturers numbers by pressing plus or minus. Press and hold to: quickly advance the number. Once done: click OK.

But the app is marginal. Can’t input device sn manually. App pop ups keep you from contacting their support

I got a device today and downloaded the app, with some error messages, connection was established and it seems to work. Not sure about voltage accuracy it disagrees with my multimeter.
