The core of 18650 lithium battery packs is cell consistency. The practical steps revolve around “cell screening → parameter sorting → series and parallel connection → equalization charging → insulation fixation → finished product testing. ”. Different algorithms of cell balancing are often discussed when multiple serial cells are used in a battery pack for particular device. The means used to perform cell balancing typically include by-passing some of the cells during charge (and sometimes during discharge) by connecting external loads. . You benefit from multi-level cell balancing in a 4S4P lithium battery pack because it keeps each cell's charge and voltage uniform.
