A battery system for a vehicle includes a battery module having a plurality of cells electrically coupled together and a first conductive element for electrically coupling the battery module to other elements in the battery system. The battery system also has a base configured for securing the battery module in place in the vehicle. The base includes a second conductive element for electrically coupling the base to the first conductive element, and a rotatable arm for securing the battery module in place relative to the base. The first conductive element is configured to contact the second conductive element when the rotatable arm is positioned to secure the battery module in place relative to the base.
