A polymer battery pack and a manufacturing method thereof. A polymer battery pack includes a core pack formed by attaching a protection circuit member to a bare cell, a case combining with the core pack and exposing the protection circuit member externally, and a resin wrapping the protection circuit board exposed through the case is provided. Strength and reliability of the polymer battery pack is improved by using the case, the bottom cover, and the resin having high strength, and the polymer battery pack can accommodate the core pack of high capacity, since no additional space is required for ultrasonic welding. |
