Why is HV better?

Hi,

Here's my take. Higher voltage with lower current draw produces similar power to lower voltage with higher current draw (P=IV). Higher current draw results in higher heat (P=IsquaredR, where R is resistance of wires & stuff). Heat is wasted energy & the enemy of the esc. This is similar to why electricity is distributed in many Kilovolts instead of the normal household voltage (something like that - my high school physics is a dim memory...)
