An embodiment is directed to a module-to-module power connector configured to form connections between battery modules installed in a battery housing of an energy storage system. The module-to-module power connector includes electrical interfaces and busbar(s) configured to form one or more electrical connections terminals of adjacent battery modules. The busbar(s) is flexibly configured to permit a defined range of movement of the electrical interfaces during insertion of the respective battery modules into respective battery module compartments. The module-to-module power connector may further be arranged inside in a tunnel space, whereby holes are defined in a battery module mounting area housing the battery modules that open into the tunnel space.

The invention relates to a connection head piece for contacting an insulated down conductor in the external lightning protection, comprising a sleeve having an axially extending first inner diameter section adjusted to the outer diameter or cross-section of the insulated down conductor for receiving one end of the insulated down conductor, and having a second inner diameter section extending axially adjacent thereto and adjusted to the outer diameter or cross-section of a stripped, exposed conductor end of the insulated down conductor, and means for fastening the stripped, exposed conductor end in the second inner diameter section. According to the invention, a static friction-generating means is formed in the first inner diameter section of the sleeve and flexibly projects into the interior of the sleeve such that a nonpositive connection is established between an outer sheath of the insulated down conductor and the sleeve upon insertion of the down conductor.
