And no, your stock ESC will work.
Another "Urban Legend."
Clearly, you have never looked at an actual discharge curve for a LiPo battery on something like a GFX that shows the actual voltage throughout the discharge cycle.
The reason they still have punch toward the end of the pack's runtime is because of the low resistance, not because the voltage doesn't decline.
