Abstract: An improved battery pack 100/200 is disclosed, having a plurality of cylindrical cells 102 arranged in parallel disposition in rows 104/204 and columns 106/206 such that positive and negative terminals of any of the cells and the closest surrounding cells are oppositely placed to minimise the overall magnetic field due to the internal current of the cells by the opposite magnetic field of the oppositely placed adjacent cells. The positive and negative terminals at any of or both of upper and lower ends of the cells 102 in a group of adjacently located columns are connected by criss-cross connections 108/208 to provide parallel electric connection of the cells 102 in groups of adjacently located columns 106/206. Criss-cross connections 108/208 pertaining to the terminals of opposite polarity are connected by series connections 110/210 to provide series connection of the sets of cells connected in parallel by the criss-cross connections 108/208.
