Hey great find, man I wish I was perfect but I'm not. You are right that's the Sensor>Voltage Threshold for low voltage warning. If you would like you can adjust this value to come at a higher or lower level. For example if you had a 19V battery you might want to set this threshold to 17.5. Or if you would like the warning to come sooner or later based on your input voltage.
C) I'm not perfect sir, but I'm working every day for our customers and will keep on trying to educate and assist.
