The vehicle traction battery pack (900) comprises a plurality of vehicle traction battery pack subassemblies 100. Each vehicle traction battery pack subassembly comprises a plurality of electrical cells (110) and an elongate casing 120 containing the plurality of electrical cells, the elongate casing being elongate in a lengthways direction 130 and comprising at least two chambers 200 arranged in a line 210 end-to-end in the lengthways direction, and at least one bulkhead 150. Each chamber 200 is separated from an adjacent chamber by one of the at least one bulkhead, and wherein each chamber contains at least one of the plurality of electrical cells. The plurality of vehicle traction battery pack subassemblies are stacked adjacent to one another in a direction perpendicular to the lengthways direction wherein the bulkheads in adjacent vehicle traction battery pack subassemblies substantially align with one another to provide at least one line (1800) of bulkheads, the at least one line of bulkheads extending perpendicular to the lengthways direction. Each bulkhead may comprise a cell connector whereby two electrical cells are electrically interconnected. Each bulkhead may comprise an insulating material such as a plastics, ceramic or an intumescent material. The electrical cells may be pouch cells or prismatic cells.
