Hi! I see in docs 19V max power supply is stated. But want to know is it even possible to feed it with 21V (using 5S LiPo)?
Because I faced with situation when 4S at maximum RPM on my octocopter makes battery voltage drop by 2 Volts itself and 0.7 Volts gets lost on wires and 1.5 Volts lost in motor itself at max current. This makes my copter work only at fully charged battery. And as battery lost couple of volts I have not enough voltage to keep flying reliably as thrust has quadratic dependance on RPM.
Thus 5S could solve all my problems if it possible to use more or less safely with Orel 20 ESC. Maybe there is some margin for power supply voltage available?
