Not saying that I want to operate at anywhere near that voltage but I'm just being curious.
In explanation:
75V DC is the limit before equipment falls under the Low Voltage Directive.
The rule is now a maximum limit as opposed to a vague mean value.
During charging batteries peak at much higher voltages (30 cell NiCd could hit 60v).
Voltages are limited by the batteries used.
