  • Publication number: 20230344073
    Abstract: A battery pack including a housing having a first portion and a second portion coupled to the first portion. The first portion has a first wall and an interface extends from the first wall. The interface includes a plurality of terminal apertures that provide access to electrical terminals within the housing. The second portion has a second wall, and the second wall is positioned opposite the first wall. A first plurality of vents extends through the first wall and a second plurality of vents extends through the second wall. A cumulative surface area of the first plurality of vents is different than a cumulative surface area of the second plurality of vents.
