@ ArguZ - "" So the 3V setting is there why?"" That's the Hobby's current standard set by LiPo manufacturers. I have yet to see on any of MY batts a low voltage warning HIGHER than 3.0v per cell and most likely why they use 3.0v as a default value that you can still adjust to whatever settings you want.
If I remember correctly before you needed to roll for some time in order to get to your desired setting as it would either default too low or default to the max I think of 60V. You then needed to roll until you reached the desired value. Only later did the selecting of CELL count and a default value showed up in an AirWare update. This was changed in the DX8 Airware version 2.00 and probably why it is what it is in the DX18 today.

It's just now we have less rolling to do, which is good. We always had to make adjustments, now you just need to make LESS of an adjustment.
PS: Some esc manufacturer still have a lower than 3.0v as there low cut-off setting so 3.0v telemetry alarm can't be that bad compared to that.
