The disclosure describes a battery assembly which comprises several gas depolarizable electrochemical cells, e.g., metal/air cells, stacked electrically in series along a first dimension. Each cell has first and second electrodes of opposite polarities. The battery assembly also comprises a housing for containing the stack of cells. The housing includes a structure for ventilating the interior of the housing and further includes first and second opposite end walls which lie perpendicular to the first dimension. The stack of cells is arranged within the housing with the first electrode of the initial cell of the stack facing the first wall and the second electrode of the final cell of the stack facing the second wall. The battery assembly further includes first and second electrically conductive connectors disposed within the housing. The first connector has a first end electrically coupled to the first electrode of the initial cell and a second end disposed adjacent the first wall. The second connector has a first end electrically coupled to the second electrode of the final cell and a second end also disposed adjacent the first wall. The battery assembly further comprises first and second terminals which are electrically coupled to the first and second connectors, respectively, and extend through the first wall to the exterior of the housing.
