Voltage display not correct

Is there a way to set battery parameters so the correct voltage is displayed?

I think I found my answer here:

At the bottom of the page it shows how to correct the voltage reading.

That should be the solution, but be sure you select 4in1 esc if you have an Iris. If you have a different copter, can’t help.
