Described is a battery 800 comprising a plurality of cylindrical cells 810 in a hexagonal pattern in a same plane, wherein a first end of each cylindrical cell of the battery is connected to an electrical end plate 830 to electrically connect the plurality of cells in parallel and, wherein each cylindrical cell of the battery connects to the electrical end plate at a corresponding electrical connection point, wherein each electrical connection point comprises a central portion 840 for connection with a terminal of a cylindrical cell and at least one fuse arm 850 extending between the central portion and the electrical connection point. The at least one fuse arm can be a continuous spiral fuse arm extending between the central portion and the electrical connection point and each electrical connection point may comprise at least two fuse arms extending between the central portion and the electrical connection point. Preferably the fuse arms are circumferentially arranged around the electrical connection point and the, or each, fuse arm can be thinner than an outer edge of the electrical connection point. The, or each, fuse arm may be formed by etching.
