Embodiment Construction
[0402] I. Power tool system
[0403] Such as Figure 1A As shown, in one embodiment, the power tool system 1 includes a set of power tools 10 (which includes a DC power tool 10A and an AC / DC power tool 10B), a set of power supplies 20 (which includes a DC battery pack power supply 20A and an AC power supply 20B) and a battery pack charger 30. Each of the power tools, power supplies, and battery pack chargers can be said to have a rated voltage. As used in this application, a rated voltage may refer to one or more of an advertised voltage, an operating voltage, a nominal voltage, or a maximum voltage, depending on the context. A rated voltage may also include a single voltage, several separate voltages, or one or more voltage ranges. As used in this application, a rated voltage may refer to any of these types of voltages or any type of range of these types of voltages.
[0404] Notified voltage. With respect to power tools, battery packs, and chargers, the advertised volta...

Abstract
A power tool system (1) includes a first power tool (10A1) having a first power tool rated voltage, a second power tool (10A2, 10A3, 10B) having a second power tool rated voltage that is different from the first power tool rated voltage, and a first battery pack (20A4) coupleable to the first power tool (10A1) and to the second power tool (10A2, 10A3, 10B). The first battery pack (20A4) is switchable between a first configuration having a first battery pack rated voltage that corresponds to the first power tool rated voltage such that the first battery pack enables operation of the first power tool (10A1), and a second configuration having a convertible battery pack rated voltage that corresponds to the second power tool rated voltage (10A2) such that the battery pack enables operation of the second power tool (10A2, 10A3, 10B).
