Usually, we want to design battery-operated systems so that nearly all of the energy stored in the battery is delivered to the load. should we design for maximum power transfer? usually, we want to design battery-operated systems so that nearly all of the energy stored in the battery is delivered to the load. should we design for maximum power transfer? no. design for maximum power transfer affects negatively the power efficiency. yes. we should design for maximum power transfer to deliver maximum energy from the battery to the load.
