A battery module comprising a housing, a venting assembly, a plurality of battery cells disposed in the housing, a printed circuit configured to control operations of the battery module, a vent chamber of the venting assembly, and a lid including the venting assembly. Each of the plurality of battery cells comprises a battery cell vent for venting gases from within the corresponding battery cell upward in a direction of the printed circuit. The vent chamber is disposed between the plurality of battery cells and the printed circuit. The vent chamber is configured to direct the gases vented from the battery cell vent toward an opening for venting the gases from the battery module. The lid is disposed over the plurality of battery cells and holds the printed circuit above the plurality of battery cells.
