If I buy a battery that comes with in line bullets, then I would run direct wire to the ESC, no sense in having more than one connector in the circuit.

I personally feel that LiHV is only necessary with stock racing, keep in mind that capacity for LiHV is overstated unless you charge to 4.35V/cell, most folks charge at 4.2V/cell to extend the longevity, however you also reduce the amount of charge going into the pack as well at the lower voltage.
