In the U.S there are bare bones Carvex kits and both the battery and power supply can be purchased separately. Also many of the new tool models can take batteries of different voltages and the tools will adjust speed and run accordingly.
The new charger also can charge several different battery voltages and amperages so not only are accessories interchangeable but also the batteries with the tools and the charger.
