I’ve tested on my uConsole+CM5 with shutdown couple times, it’s ok,no need to remove battery
just have once hanged during shutting down
But I am ok with this result,since CM5 is not officially supported by CPI yet, official CM5 support board will come out soon.
So if your uConsole is new ,then this every shutdown battery remove situation should be a after-sales issue
