Naza Lite Voltage Monitor setting values

[tbs2]

My account is brand new but I have been visiting this forum for a while. I have a F550 with Naza M lite, 4s lipo and 8" props. I turned the voltage monitor off since I couldn't figure out what the setting values should be.

I ran my 4s until exhausted with the protection off. The reading was about 14.2v. I tried so many different combinations but the red light keeps coming up after 1-2 min of flight time. Please let me know the value below should be.

My setting:

First Protection
No Load 15.0v - Loss 0.6v = Loaded 14.4v

Second Protection
No Load 14.4v - Loss 0.6v = Loaded 13.8v

Thanks

Or can anyone share their F550 4S Lipo voltage protection setting?
