A battery unit 800 for mounting into an electrical vehicle chassis. The battery unit has an outer casing, a battery mounting frame that is arranged to be accommodated within the outer casing, and a plurality of battery modules that are arranged to be supported upon the battery mounting frame. The battery unit is mountable onto a bulkhead 202 of the chassis of the electrical vehicle to provide increased torsional strength with respect to an elongate axis of the electrical vehicle. The battery mounting frame may have a bottom support panel, a plurality of partitioning plates coupled to the bottom panel, and at least one transverse load-bearing plate orthogonal to the partitioning plates. The mounting frame may also have mounting rods supporting the battery modules. The battery unit may also have a cooling arrangement. The battery unit may be mounted in a cavity in the bulkhead, and the outer casing may be made from one of the following materials: aluminium, stainless steel, magnesium, ceramic, carbon fibre, or glass fibre. Also disclosed is a method of providing an increased torsional strength to a chassis by providing the abovementioned battery unit and mounting it in a cavity formed with the bulkhead.
