Busbar for battery electrode post connection and battery voltage monitor using the same

A busbar for battery electrode post connection with a terminal for voltage detection, wherein:

• both ends of a length direction of a rectangular thin plate of a conductive metal are left to connect a first busbar and a second busbar and an elongated opening is formed in a center of the first busbar and the second busbar;
• two holes through which an electrode post of one battery and an electrode post of an adjacent battery are inserted are respectively formed in the rectangular thin plates of both the first busbar and the second busbar around the elongated opening of the center;
• a terminal for voltage detection is extended integrally to the rectangular thin plate from an edge of the rectangular thin plate;
• the two holes of the first busbar and the two holes of the second busbar overlap in a state where the rectangular thin plate is folded in two with respect to the elongated opening;
• and
• the terminal for voltage detection is integrally formed with the rectangular thin plate and is erected by folding the terminal for voltage detection in a direction perpendicular to the rectangular thin plate.
