Battery pack for an electric-powered road vehicle comprising: a plurality of planar electrochemical cells arranged in a pack pattern; wherein each cell comprises terminal poles at a first edge; a support facing the terminal poles of the cells; a plurality of elastically deformable spring-conducting elements having first ends coupled to the support, wherein the spring-conducting elements are arranged in rows so that when the battery pack is in use each row of the spring-conducting elements is pressed against the terminal poles of a corresponding cell to make a conductive bridge between each cell and the support; wherein the terminal poles of each cell are connected to one another by a longitudinal welding line parallel to the first edge of the corresponding cell; wherein for each cell a conductive plane is provided between the terminal poles and the corresponding row of spring-conducting elements; wherein each conductive plane is constrained to the corresponding terminal poles by means of points or transverse welding lines at the space provided between two adjacent spring-conducting elements of the same row.
