The present invention relates to vehicle comprising a body having first and second layers that form at least part of a monocoque structure; a battery comprising cylindrical cells held together by a bonding material in a hexagonal pattern in the same plane, bonding a surface of a cell to an adjacent surface of an adjacent cell with triangular gaps between the cells, wherein the battery is located between the first and second layers; and connecting means for mechanically fixing the battery to the first and second layers. The cylindrical cells can be held within a cuboidal container that is fixed to the vehicle body by epoxy resin and/or reinforcing fiber, or by a surrounding flange that is rigidly fixed e.g. glued, welded, bolted or riveted, to the vehicle body. One of the first and second layers can be an outer skin of the vehicle. Preferably, the battery has a positive and negative terminal wherein the negative terminal is electrically connected to the outer skin. The vehicle can be an automobile, motorbike, scooter, e-mobility platform, watercraft, submarine, eVTOL helicopter or aircraft. A method of manufacturing a vehicle comprising said battery is also described.
