Abstract
A battery for powering a wearable device comprises a first cell, a second cell interconnected with the first cell, and a connection electrically coupled between the first cell and the second cell. The connection extends from the first cell to the second cell along a first direction. A length of the connection along the first direction is greater than a distance between the first cell and the second cell. In some embodiments, the connection comprises a folded structure configured to accommodate a dimensional change of the battery when bending the wearable device.
