That is minor and must be solved at the same time when you figure out how to generate supply voltage for your ESC microprocessor and subsystems (It is complicated going from above 35V down to 5).
You still need to sample supply voltage, if you plan to monitor battery voltage to use LiPo cutoff.

As far high voltage problems, it is a complex to describe, but think of your ESC as a hammer. When it is small you can use it and neighbors won't even hear you, while if you start using pneumatic one then entire neighborhood will know that you mean business. :)
