1. A battery pack comprising:
- a frame comprising a first side plate and a second side plate spaced-apart from the first side plate;
a plurality of first ribs disposed spaced-apart from each other along a first direction, each first rib having opposite ends respectively coupled to the first and second side plates and comprising supporting grooves formed in lateral surfaces extending between the opposite ends, any portion of said each first rib not directly contacting, any portion of another first rib which is immediately adjacent to said each first rib; and
a battery group comprising battery rows each including a plurality of secondary batteries, the secondary batteries inserted along a direction perpendicular to the first direction in spaces formed by the supporting grooves of adjacent first ribs, each of said plurality of secondary batteries having a cylindrical shape, and the supporting grooves are formed offset from each other on the lateral surfaces of the first ribs so that no two adjacent batteries of said plurality of secondary batteries are in a same geometric plane in both a horizontal axis and vertical axis; and
first connection taps for electrically connecting portions of first end portions of the secondary batteries, said first connection taps consisting of a rhombus shape with four straight sides of equal length, opposite sides that are parallel and opposite angles that are equal with no angles being right angles.
