Abstract
An adapter connects a plurality of first battery packs, each having a nominal voltage of about 18-36 volts, in series to an power tool having a rated voltage that is 36 volts or higher. The power tool includes a second battery interface configured to removably attach a second battery pack. The adapter includes a plurality of first battery interfaces configured to removably attach the plurality of first battery packs and having a different physical configuration than the second battery interface. A connector of the adapter is configured to be removably attached to the second battery interface. A plurality of visual indicators is disposed on the adapter such that they have the same or substantially the same illumination direction and they visually indicate at least a level of charge of each of the first battery packs attached to the adapter.
