I was checking the voltages for the hell of it with my meter and it's a little strange.. once I reach the 4.5 mark I only have to move it a hair and it goes up .1 volts.. when I get to 5.2 it's barely passed the yellow and then the .1 increments are spread our wider on the wheel if that makes any sense. Is that normal? I can get used to it just found it odd.
