A battery assembly includes a plurality of battery subassemblies. The battery subassemblies are operable to be mechanically and electrically connected together to form a battery assembly and are provided to be shipped such that an additional shipping fee that would be incurred due to a battery characteristic that is not the total weight of the battery assembly is avoided. The plurality of battery subassemblies includes a first battery subassembly and a second battery subassembly. The first battery subassembly includes a first subassembly to subassembly electrical connector, a first subassembly to subassembly mechanical connector, and a device power connector operable to supply power to a battery powered device. The second battery subassembly is operable to be electrically and mechanically connected to the first battery subassembly and includes a second subassembly to subassembly electrical connector for electrically connecting to the first subassembly to subassembly electrical connector of the first battery subassembly and a second subassembly to subassembly mechanical connector for mechanically connecting to the first subassembly to subassembly mechanical connector of the first battery subassembly.
