A battery comprising a plurality of cylindrical cells held together by a bonding material in a hexagonal pattern in a same plane, bonding a cell surface to an adjacent cell surface with triangular gaps formed therebetween, and wherein a first end of each cell is connected to a first electrical end plate to electrically connect the plurality of cells in parallel, and wherein at least one channel is provided to direct coolant flow across the first electrical end plate to cool the first end of each cell. Fuse arms may connect the cells to the electrical end plate. The battery can include a first coolant end plate comprising the at least one channel within, adjacent to the first electrical end plate with or without a first electrically insulating membrane sandwiched between. Preferably, the at least one channel creates turbulent flow of coolant by comprising a sharp edge or zigzag form. The bonding substance can be an epoxy resin and the coolant may be a non-conductive fluid e.g. dielectric oil or de-ionised water. The battery is suitable for use in the body or chassis of a vehicle. A battery pack, cooling system, and method of battery manufacture are also described.
