Abstract: A battery system includes a first cell that is electrically connected to a second cell via a push-on clip. The clip is an electrically conductive plate that includes a first cutout that is configured to receive and snap onto a first terminal of the first cell, and a second cutout that is configured to receive and snap onto a second terminal of the second cell. The first and second cutouts are irregularly shaped and formed in the peripheral edge of the clip. The first and second terminals each have a widened distal end, and an interference fit is formed between the clip cutouts and the corresponding widened distal end, whereby a secure electrical connection between the terminals and the clip is provided.
