Nope. I’m not in the lab any more, but it was not.

no idea then.
There is no status where red and green LED are constantly on as far as I remember.
If green was flashing once per second (with red on) then that would be cell error.
anything in the V5 log ? That would also show cell error.

Debug option in V5 Firmware updater app - very useful for taking a closer look at battery issues.
