Background. If li-ion cells are arrayed (series x parallel — S x P or P x S) to form a battery, it is generally recommended to manage parallel stacks of series cells (P x S) independently, such that each individual stack may be managed with an independent BMS, as depicted below.. This is because a typical BMS IC will assume that all parallel …
