eureka !!!
I solved it whit fowlling script in /etc/sensors.d/sensors.conf
Code:
chip "it87-*"
label in8 "Vbat"
compute in3 @*((6.8/10)+1), @/((6.8/10)+1)
compute in4 @*((30/10)+1), @/((30/10)+1)
compute fan1 @/4, 2*@
compute fan2 @/4, 2*@
And aditional script in ~/.conkyrc
After
+5,0V:${hwmon 1 vol 3}V
Before
+5,0V:${exec sensors | awk '/in3/ { print $2 }'}V
