Is current sensor mandatory?

Hello,

I build another FPV glider, and in this one I try yo have a very light setup. So I don’t want to use a standard power module with a voltage and current sensor.
I only use a DC-DC converter and a divider made with resistors, so I will not have a current sensor.

Ardupilot will see a current equal to zero all the time, maybe it will trigger a security ? Is there something that use the current value ?

Thank you for your help

Ardupilot is really a great project
