Switching between two power sources (LiPo cells)

by w4tchd0g   Last Updated October 09, 2019 19:25 PM - source

I'm building a circuit with a 2S or 3S LiPo as power supply. If a 2S LiPo is connected the circuit should be powered with 2S (7,2V). If a 3S LiPo is connected the circuit should be powered with the 3rd cell (11,1). The problem is that I can not have a voltage drop because I need that voltage at the output, so I can not use diodes. Does anyone have an idea how I can realize that?
