The present invention provides an electrical vehicle battery system comprising a battery base unit (20) and one or more stackable supplemental battery unit (30) that may be joined thereto. The base unit (20) has a housing, an electrical storage cell within that housing, and mounting means (22, 23) to connect the base unit to the electrical vehicle and to provide electrical power. The base unit further comprises connection means (25, 35, 36) by which one or more supplemental battery unit may be attached to an upper surface of the base unit to supply electrical energy thereto. The supplemental battery unit has connection means (33, 34, 38, 40, 42) which cooperate with those of the base unit. Further equivalent supplemental battery units may be attached to the top of the supplemental battery unit (30). A load bearing surface (21, 31) is defined by the battery system thereby to support cargo on the vehicle.
