Abstract
An exemplary battery pack comprises a battery cell having a first terminal and a second terminal disposed on a first end of the battery cell. A support member is attached to the first end of the battery cell, and a first L-shaped contact is connected to the first terminal via a protection circuit module. The protection circuit module is configured to disconnect the first terminal from the L-shaped contact upon a disconnect event. A second L-shaped contact connected to the second terminal, and a top cover encloses the first end of the battery cell, the support member and the protection circuit module. The first and second L-shaped contacts are exposed through corresponding apertures in the top cover, and a label including a body section and first, second, third and fourth flap sections is wrapped around the battery cell such that at least one of the flap sections secures the top cover to the battery cell. A cutout area can be provided on one of the flap sections to expose the L-shaped contacts for interfacing with device or connector contacts.
