Older APP solved the issue .... now the BMS seams like to be working as it should
I also wrote a message in the message center on QUCC Official Store of Aliexpress that says:
Fortunately there is a very useful forum on the net where I discovered that using the old APP version 3.1.1026 I can adjust all the parameters I need.
I am a mechanical engineer who works in the automotive sector and I use an electric scooter as a means of transport where I installed the battery, motor and controller by myself using the components available on the market.
Please write this message from a mechanical engineer to your software engineer: " This procedure where you have to authorize the BMS owner to adjust the parameters is one of the biggest bullshit I've heard in recent years because when a customer buys your BMS must have access to change the battery parameters within 2 hours of turning on the BMS."
