Hello llorch, Thanks for the support bundle as it helps look into your issue.  So, what you had happen is a battery test on your MD3000.  The battery on controller1 is showing as charging currently.  The battery on controller0 is showing as optimal.  If the battery fails to chare fully then you will need to replace it.  Also, I noticed that you are running old firmware on your MD3000.  The last version that was created is 07.35.39.64.  Here is the link to the newer firmware if you want to upgrade it.  [URL] Please let us know if you have any other questions
