Show battery status (PS3 Controller)

[bubbler]

Hey, is there a way to show the current status of the PS3 Controller.
I had the problem that suddenly I could not do anything in the game because the battery was empty.
Found this for RetroPie, is there something similar for Recalbox or can this be used for recalbox as well?
