In this note we analyze the BPS black hole equations in extended\nsupergravities and we find two interesting relations involving first and second\nderivatives of combinations of the central charges. One relation is a new\nidentity that solely relies on the geometric properties of the scalar manifolds\nof extended supergravity theories. The other relation is a generalization of a\nscalar weak gravity conjecture relation conjectured by Palti and uses\nproperties of the underlying black hole solution. We also provide for the first\ntime an explicit covariant construction of the BPS squared action for such\nsolutions.\n
