Four different batches of 18650 lithium-ion cells have been measured to obtain initial capacity. The obtained measurements are analyzed to evaluate off the shelf capacity dispersion and other statistical parameters which are used to estimate the likelihood of a good battery (similar capacities for all cells) if cells are selected at random. Additionally, capacity dispersion results are discussed to select appropriate cell balancing methodology.
