BATTERY PACK

Abstract

A battery pack is disclosed. The battery pack includes one or more battery assemblies and a circuit board connected to the battery assemblies. The battery assembly includes first and second battery cells having the predetermined surfaces overlaid on each other. The first and second battery cells each have battery elements accommodated in a container thereof, and cathode terminals and anode terminals are provided at a same height as the predetermined surfaces at a same side. The cathode terminal and anode terminal of the first battery cell are adjacent respectively to the cathode terminal and anode terminal of the second battery cell.
