Does 54V FLEXVOLT give more runtime AND more power?

54V always gives more power, this will be more evident during harder applications. This increased power opens up applications that were previously not possible on cordless. Attempting similar applications on lower voltage cordless tools will put a strain on the tool and most likely drain the battery quicker as the tool is not working efficiently. Due to the higher power level 54V offers a significant speed of application advantage vs. existing cordless in certain applications (e.g. cutting 2 x 4” timber with a circ saw). Because the application is completed more quickly the total amount of energy required is less despite the higher power levels, leading to increased runtime.
