Abstract: A battery pack, an electrical combination and a method of operating a battery pack. The battery pack may include a housing; a plurality of battery cells supported by the housing; a plurality of terminals including a positive power terminal, a negative power terminal, and a low power terminal; a low power circuit connecting the plurality of battery cells to the low power terminal and the negative terminal to output a first voltage; and a power circuit connecting the plurality of battery cells to the positive power terminal and the negative terminal to output a second voltage, the second voltage being greater than the first voltage. A terminal block for one of a battery pack and an electrical device may include a terminal with a terminal blade, and a terminal support portion.

Abstract: A power tool (10) includes a battery pack (20), one or more sensors (70, 72), an indicator (74), and an electronic processor (62) coupled to the battery pack (20), the one or more sensors (70, 72), and the indicator (74). The electronic processor (62) is configured to: detect, using the one or more sensors (70, 72), one or more parameters of the power tool (10); determine a system performance based on the one or more parameters; determine a system performance level based on the system performance; and provide, using the indicator (74), an indication corresponding to the system performance.
