You can connect a current sensor if you want to use one.

That is very nice!
Are those ESC's flashed? Sounds like they are not.

No. I don't use flashed ESC because many of our clients don't use that. And I have flashed ESC. I don't think they perform better on stabilization horizontally and vertically. There are many things to do to make the quad steady.

Or I think I don't know how to use the flashed ESC correctly. Could you share your experience on that, please?

Difference between stock and flashed esc is in throttle response and you can set higher PID's and you will not have quad wobbles and you will not have ground effect.

Does flashed ESC means ESC with Simonk firmware?

hmmm,
regular, non simonk, esc's do add a timedelay because of the internal filtering.
removing the timedelay allows higher pid settings.
the direct command output adds very much in terms of stability!

Do you make big difference on the throttle curve to keep the quad vertically stable with flashed ESC compare to non flashed ESC ?
Thx

i am consequent as i keep the calculated rotation speed difference of the props. in place.
this on both boundaries - means dynamic increase of the throttle in case the
minimum output drops below the min settings for the motors.
the other boundary means cutting the throttle

there is one momentum i have no control over.

Less vibration makes bigger difference.
