The cell connector system includes a base contact profile with at least two end surfaces, a support surface, a transition surface, two opposing contact surfaces, and at least one lamella contact. The support surface can be placed on at least one frame device. At least one contact surface has a receiving recess with at least two retaining protrusions that receive the lamella contact. The lamella contact can establish a separable electrical connection to the conductor tab of the electrical single cell. ## Claims ### Claim 1 A cell connector system for connecting at least one single cell of an electrical storage module, wherein the single cell has at least one conductor tab and the electrical storage module further has at least one frame device, wherein the cell connector system
