Manufacturing an electrically insulated cluster (300) of cylindrical electrical cells (100) for a vehicle battery. The method comprises providing (402) a cluster (300) of cylindrical electrical cells (100), the cluster having a first end (304), a second end (302) opposite the first end, and a contoured side surface (310) extending between the first and second ends. The electrical cells (100) of the cluster each have parallel longitudinal axes aligned between the first and second ends. The method (400) comprises providing (404) a sheet (218) of electrically insulating film; wrapping (406) the sheet (218) around the contoured side surface (310) of the cluster (300) to engage a first surface (218c) of the sheet (218) with the contoured side surface (310) and surround the contoured side surface (310) of the cluster to electrically insulate the contoured side surface (310) of the cluster; and adhering (408) the first surface (218c) of the sheet to the contoured side surface (310). Thus, dielectric coverage of the contoured side surface of the cluster is provided. The method may comprise moulding a sheet to the contoured surface by pressing a jig against the surface.
