<p>A battery pack using circuit board 20 as electric connection to connect battery cells 50 includes a circuit board, plural conductive pieces 30, protection components 40, battery cells, and a conductive circuit. The circuit board includes plural openings 23. The conductive pieces each include a first conductive section 31 electrically connected to the top surface of the circuit board, a middle section 32 abutted against the inner surface of the openings, and a second conductive section 33 inserted through the openings toward the bottom surface. The protection components are fixed to the top surface of the circuit board. The battery cells each have two conductive terminals (51, fig 5) aligned with the openings and electrically connected to the second conductive section. The conductive circuit is electrically connected between the battery cells, the conductive pieces and between the conductive bases of the protection components, and each of the battery cells is electrically connected with a corresponding one of the protection components. Preferably, the conductive pieces are connected to the battery terminals by welding.</p> |
