<p>A battery adapter (20; 40; 50) can include a plurality of machine-side-connecting sections (22c, 22d) capable of being connected to a plurality of battery-connecting ports (127c, 127d) provided on an electric machine (12), and a battery-side-connecting section(s) (23) to which a battery or batteries (30; 60) can be connected. The number of the machine-side-connecting sections (22c, 22d) is preferably configured to be larger than the number of the battery-side-connecting section(s) (23). Further, the electric machine (12) is preferably connected to the machine-side-connecting sections (22c, 22d) of the battery adapter (20; 40; 50) through its battery-connecting ports (127c, 127d). The electric machine (12) can be driven by the battery or batteries (30; 60) connected to the battery-side-connecting section(s) (23) of the battery adapter (20; 40; 50).</p> |
