Thinking more about this, it might make more sense to simply accept a 100
value and not accept a 0 value in the stop case (I tried multiple times to
write 100 to a stop_charge_thresh file, because that feels more natural).

Having a 0 mean 100% is just odd. So stop_charge_thresh should simply
accepts integer values in the range [1, 100] (and start_charge_thresh
should continue accept [0, 99], as 0 really means 0 there).
