Throttle saturation and uncontrolled descent

Hello everyone,

I am in trouble because my drone crash when I was Landing.

In fact, I had the alert “Thrust Loss” many time when the voltage of the battery decrease. I understand that the power remaining in batteries was not enough to allow the drone to maintain altitude.
But, when I use PX4, this problem doesn’t happen : I think ArduPilot don’t allow motor or ESC to use the maximum power they can.

How could I increase this maximum power ?

Thanks !
