PURPOSE: Provided is a battery pack capable of charging/discharging, which comprises a plurality of secondary batteries, can be compatible with common batteries, and has a protection circuit module(PCM) therein. CONSTITUTION: The battery pack(100) comprises: a charging electrode and a discharging electrode; upper and lower circuit boards(50, 60) having the PCM which breaks the electric current supplied to a battery cell when the charging electrode is charged with an excessive electric current and breaks the discharge of the battery pack when an output voltage of the discharging electrode goes down under the fixed voltage; a cathode connection conductor(20) connecting cathode terminals of respective batteries(10a, 10b) serially and connecting the cathode terminals to the charging electrode and the discharging electrode electrically; a first anode connection conductor(22) and a second anode connection conductor(24) connecting anode terminals of the respective batteries(10a, 10b) serially and connecting the anode terminals to the charging electrode and the discharging electrode electrically through the PCM; upper and lower fixing caps(30, 40) for fixing the upper and lower circuit boards(50, 60); upper and lower covers(70, 80) fixing the respective batteries(10a, 10b), the fixing caps(30, 40), the cathode connection conductor(20), the first and second anode connection conductors(22, 24), and the circuit boards(50, 60) in one battery pack form. |
