More Battery Options/Features
1. Say if a grids reactors have run out of uranium batteries should have an option to automatically turn on when power fails. (Maybe after 5 seconds)
2. Disable batteries when they have fully charged (So that their stored power cannot be used)
3. Allow specifying where they get their charge from (Reactors or Solar Panels, or in the future, if their implemented, Hydrogen Generator or Wind Turbines) . Have these as check boxes so all or none of them can be selected. Or this could be an option in the power generators to specify where there power will be directed (A specific grid/sub-grid or batteries).
