Battery stats on Frontpage as an aditional Line

my wish is an additional Value on the Frontpage to show the actual Battery status 0-100%.

i think more and more guys in future have an storage unit and wana see this state.

the thing with the overlays on the extended Page, in my case there are to less overlays to “build” the frontpage on the last page.
alternative may be its possible to show one of the extended values on the Frontpage.
