If the batteries get bricked, most likely the wrong firmware was installed. There is a small issue with the data not showing properly, but it will not brick the battery.

I just updated both of my batteries 280 Ah indoor with this latest 485 and 232 and now my monitor is only reporting one battery with weird characters in the battery name.  I guess I'm going to do what others have a revert back to the previous ver.
