1. A power source apparatus comprising:

  • a plurality of batteries, wherein each of the batteries has a positive electrode terminal and a negative electrode terminal disposed separately on a same surface of the battery;

    a plurality of parallel blocks, each of the parallel blocks having a number of the batteries stacked together and electrically connected in parallel, wherein each of the parallel blocks has a set of the positive electrode terminals lined up at one side and a set of the negative electrode terminals lined up at the other side of a common surface formed by the surfaces of the batteries formed when the batteries are stacked into the parallel block as a single unit,wherein the parallel blocks are electrically connected in series to form a multiple parallel series connected block, and the parallel blocks are stacked to form the multiple parallel-series connected block having an orientation with respect to a position of the positive electrode terminals and the negative electrode terminals; and

    a plurality of bus-bars, each of the bus-bars having a plurality of insertion holes receiving the positive electrode terminals and the negative electrode terminals so that the batteries are electrically connected to each other,wherein the multiple parallel-series connected block has two parallel lines of the electrodes spaced apart from each other, and each of the lines of the electrodes is arranged alternately by the set of the positive electrode terminals and the set of the negative electrode terminals in the stacking direction of the batteries, andwherein the bus bars extend in a stacking direction of the batteries along each of the two lines of the electrodes, and at least one of the bus bars successively lies from the set of the positive electrode terminals to the set of the negative electrode terminals which are arranged side by side so that the bus bar electrically connects the batteries in the parallel block in parallel and simultaneously electrically connects the parallel blocks positioned side by side in series.
