A vehicle traction battery pack subassembly (100 fig 1A), a vehicle traction battery pack (900 fig 20) and a vehicle (2100 fig 21) are provided. The battery pack (100) comprises: plural electrical cells 110 in a casing (120 fig 1A) elongated in a lengthways direction 130. Each cell 110 comprises front and back faces (111,112 figs 1B,C), and ends (113,114 figs 1B,C), between which the faces (111,112) extend. Terminals (115,116 figs 1B,C) are provided for the cell 110 at the respective ends (113,114). At least one line 140 of end-to-end cells 110 is provided in the lengthways direction 130. Several subassemblies (100) may be provided side by side. Each casing (120) may include overlapping C-section open profile elongate sections (350,360 fig 3) forming lips (31,320 fig 3) which meet respective indents in casings of adjacent subassemblies. The invention is aimed at providing suitable structural strength and energy density without excess bulk or weight or undue reliance on other structural components for strength.
