Hello everyone! I have a quick question. I recently bought an ecotech vectra m1 and the ecotech battery backup with the adapter, all used. When connecting the backup adapter cable to the m1 controller it only goes in about halfway (see picture). I opened up the controller thinking maybe the port is broken, but its actually very shallow and the plug goes in the full length of the port. Those of you who are using this setup, are you dealing with this too or is something wrong?
