Mini power brick configuration

Where can I find the config manual/settings of mini power brick in MP? Which one should be select in the power module list?

These should be the default Battery Monitor parameters for the power brick that ships with the Cube. These are for plugging into the PM1 port. PM2 changes the current and voltage sense pins. You should test the sensing to make sure the one you have is pretty close to the spec. From my experience this sensor does not do a great job with voltage under 6V and under 5A.
