We report on head-on collisions of charged black holes. We focus on non-spinning black holes, starting from rest and with the same charge to mass ratio QM. The addition of charge to black holes introduces a new interesting channel of radiation and dynamics, most of which seem to be captured by Newtonian dynamics and flat-space intuition. The amount of gravitational-wave energy generated throughout the collision decreases by about three orders of magnitude as the charge-to-mass ratio QM is increased from 0 to 0.98. This decrease is a consequence of the smaller accelerations present for larger values of the charge.
