Menu..Charge..Battery Menu...Limits.... last item is Hi Batt, set to 170 degrees Celsius. That is ridiculously high.
Yes, you're right. It is set ridiculously high so that it is "disabled"
Setting it to a correct setting for your batteries would be dependent on your particular battery specs.
That is why it is REAL high as a default. I agree that it could have ben lower, say, 100C
