An energy source monitoring system evaluates the state of an energy source a nd responsively controls a power tool or other device. The energy source may be, for example , a power tool battery pack that includes multiple individual battery packs connected in series. The energy source monitoring system may be incorporated into a power tool, screwdriver, flashlight, audio and/or video player, or any other device. The energy source monitoring syste m intelligently exercises control over the power applied to the device (e.g , to the motor i n the device). In one implementation, the energy source monitoring system detects when voltages in the energy source have fallen below a cutoff level, yet allows the device to continue running until the operator finishes the current device operation (e.g. a miter saw cut, or playback of a song).
