The UPS HAT is turning off after 30 seconds to 2.5 minutes for no apparent reason. It initially did not do this and had ran for over a week initially but early last week we finally received the 18650’s and installed one, the UPS Hat would just turn itself off as described above.
I have been fighting with it this one ever since (we have 6 UPS HATs, 3 have not been tested yet, 2 seem to be working fine but no software or battery has been installed out of fear the same thing will happen). Initially we did not have any of the software configured as the behaviour without the software was fine for our use case (and because we were using just Debian Buster it didn’t want to install anyway).
In troubleshooting this, I have switched to the official full Raspbian release, installed the software as outlined in the Getting Started guide. To accomplish some of this, I ended up powering the Pi directly so that it could run long enough to actually install software.
Later I found the manual firmware upgrade instructions because the pi would not stay running long enough for the remote management to allow a firmware upgrade. I have updated the firmware to the latest available v0.3.22, I am not 100% convinced that the firmware update has been fully applied as the everything powered off during please wait part of the firmware upgrade (see below).

I left it for 2 minutes and it did not come back up so I pressed the S1 button to turn it on. It ran long enough to do the following (unfortunately I didn’t time it, but I doubt it was more than 2.5 minutes):
$ ssh pi@192.168.20.114

If I boot into firmware update mode (purple L1) the UPS HAT stayed on for over an hour before I tried to flash the firmware.
At this point, I am not sure if I am missing something or it has gone bad somehow.
Thanks,
