"Yeah. the use of diodes for this is arcane; even multiplexing 5V power inputs as in the PixHawk. Note that if the diodes are properly rated, they won't "burn". Simply put, simple use of a few of today's high power, low cost…"

"Schottky diodes has a dropout voltage of (in the best case) of 0,3V With 120 Amps the power loss is P=V*I = 0,3*120=36W... A lot of power will be disspated in heat and the diode could burn very soon. We developed an ideal diode controller with a…"
