Yeah I’ve never understood this for lithium ion systems. Maybe some parallel or series the cells differently to get different total max power outputs? But I don’t expect that would affect cost either way.
With flow batteries there are definitely differences since the power and energy components of the system can each be scaled independently from each other. Ie need more total energy then just expand the amount of liquid electrolyte storage you have.
