These 48v parts look like a probable financial nightmare for the second owner.

 

Maybe, maybe not. It's just electrical stuff anyways.

Automobiles started off with 6V parts.

When that wasn't enough, they moved onto 12V stuff which lasted to this day. Same was said of the 12V parts being a financial nightmare way back then.

12V has a power limit, you can only push so much current through a wire, hence the invention of 48V to raise the power limit. 

 

Implementation. Invention would be something different. 
Now, with 48 volts they are literally EVs. No need to have electric cars now. 🥳
