Dam u should have brought it to a dealer straight away alot of the downtube batterys were called back because of a connection issue and then they sent a bracket that goes over the connectors,but my bikes a horizontal battery thatsits under the backrack there known to be the best in terms of reliability i think my problem is a easy fix if the display would stay on long enough to connect to the Bluetooth i could do a check.what does your app say?I have a giant stance e+2 2021 and it just cut of won’t turn back on no error codes or anything tried a new contorller new battery and still nothing gonna change the discharge connector next and fingers crossed I have life
