One thing about min voltage is the steepest hill you have to overcome, with the largest cargo and deadest battery. That's where you will experience the highest voltage drop. It also depends on tire size and/or rear end ratio. I had mine set too conservative (dunno the settings before or after), and they would momentarily drop below that point while climbing my steepest incline. If you live in flat-land, you have it easier.
