Kastor–Traschen (KT) type solution in a cosmological set up is studied in this article. We examine a hybrid of a KT metric and a Friedmann-Robertson-Walker-Lemaitre (FRWL) solution. The prob-lem is treated in a general number of dimensions D ≥ 4 and we include the cosmological constant Λ parameter into the Einstein– Maxwell equations. The matter source consists of two fluids – charged dust and neu-tral fluid with non-vanishing pressure. The equations of motion for the fluid and electromagnetic (EM) field are written down and an exact solution generalising the ex-tremely charged Reissner–Nordström black hole to an arbitrary spa-tial curvature parameter is presented. We examine metric and sin-gularities of curvature scalars, trapped horizons as well as energy conditions.
