Abstract
A device, such as a power tool, configured to receive a battery pack that is operable to determine a type of battery pack that is attached to the device. When the battery pack is connected to the device, the device is configured to determine an impedance of the battery pack. Based on the determined impedance of the battery pack, the device is capable of detecting the particular type of battery pack that has been attached. In some embodiments, the device is configured to be controlled based on the type of battery pack that has been detected by the device.
