  Current astrophysical observations show that on large scale the Universe is
electrically neutral. However, locally this may be quite different. Black holes
enveloped by a plasma in the presence of a strong magnetic field may have
acquired a significant electric charge. We can also expect that some of these
charged black holes are moving. Consequently to describe them we need spacetime
metrics describing moving black holes. In general relativity such a solution is
given by the charged C-de Sitter-metric. In this article we will assume that it
can be used to describe moving charged black holes. We will investigate how to
observe the electric charge using gravitational lensing. First we will use
elliptic integrals and functions to solve the geodesic equations. Then we will
derive lens equation, travel time and redshift. We will discuss the impact of
the electric charge on these observables and potential limitations for its
observation.
