A battery pack of the type that may be used in an electrically-powered vehicle comprises first and second arrays of cells disposed adjacent one another, and a housing enclosing the two arrays. The housing defines a cooling chamber surrounding heat transfer surfaces of the cells, a first manifold sealed from the cooling chamber and collecting gasses generated by the first array, and a second manifold sealed from the cooling chamber and collecting gasses generated by the second array. A tunnel connects the first and the second manifolds to allow passage of any collected gasses from the first manifold into the second manifold, and a discharge opening in the second manifold allows the collected gasses to escape from the housing. An electrically conductive bridge bar extends through the tunnel and connects the first array with the second array.
