Abstract: A battery module includes a housing that defines an inner volume and includes an airflow path from an aperture formed in a first end member of the housing, through the inner volume, and to an aperture formed in a second end member of the housing; a plurality of power cells mounted in the inner volume of the housing, each of the power cells including a vent member at an end of the power cell; and a flame arrestor mounted across the airflow path and between the plurality of power cells and the aperture formed in the second end member of the housing. The flame arrestor includes a screen that includes a plurality of fluid pathways sized to allow an airflow from the airflow path through the fluid pathways and sized to impede a combusted fluid to pass therethrough.
