3s 11.1v Lipo - Voltage Telemetry showing 11.5v

[RCTechGuy]

I've installed a voltage tap on my truck and the value I'm getting off a 3s 11.1v lipo is 11.5v. How could this be? Very confused here.

It's per cell, the full charge will be 4.2v per cell, the storage will be about 3.7v per cell and the low voltage cutoff will be 3.2v per cell.

For a 3s:
4.2v x 3 = 12.6v
3.7v x 3 = 11.1v

You will get different readings while it's draining.

Thanks for the information. What I am confused about is that I'm getting a reading of 11.5v. How is it able to put out more that 11.1v per cell?

I'm using an FPV setup for my bomber. The goggles, the camera OSD and the LiPo monitor won't show the same voltage. I guess it's all the wiring and resistances?

It's not putting out 11.1 volts per cell, it's reading the entire pack, which is 3 cells. Read the first reply you got, explains everything.
