  In the present paper binary configurations of identical corotating
Kerr-Newman black holes separated by a massless strut are derived and studied.
After solving the axis conditions and establishing the absence of magnetic
charges in the solution, one gets two 4-parametric corotating binary black hole
models endowed with electric charge, where each source contains equal/opposite
electric charge in the first/second configuration. Since the black hole
horizons are given by concise expressions in terms of physical parameters, all
their thermodynamical properties satisfying the Smarr relation for the mass are
also obtained. We discuss the physical limits of both models.
