@AshwinVijayakumar on your advice I tried a buck converter and it seems to be working a treat. I was struggling with the NCS and my other pi peripherals(an LCD screen) causing low power throttling.. this seems to have completely fixed it. I used this device: https://www.amazon.com/gp/product/B06XRDV49T/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
Here is a video of my car running
Car driving my neural network on the pi, the NCS is doing object detection (not really affecting the car driving yet)
In regards to using the built in ECS for power. My ESC returns 6v on the BEC to drive servos. Almost just right, but I worried that there wasn't enough difference between the BEC 6v and 5.2v needed for the pi for a buck device to work well. All the specs I read seems to require at least 1.5v difference. I would like to try it anyway as more regulation is probably a good thing (filtering out high freqency noise etc) Im no electronics expert for sure.. maybe I should just use a resistor to drop that .5v from the BEC? suggestions? Oh, and to be clear, I'm using the Micro USB port for power IN on the pi, as I assumed there was probably some useful filtering\buffering\regulating or whatever going on on that input. Was that a reasonable thought?

I just wanted to report back that I have been very successful at getting the NCS running on my PI. I have googlenet inference and tinyyolo examples working. I am integrating this into my autonomous RC car. (donkeycar)
My issue is with powering the Pi with the NCS plugged in. Its very sensitive. I frequently end up with the pi throttling due to low voltage. Any suggestions for powering the NCS on a mobile platform via battery?
FYI: I'm using the 'vcgencmd get_throttled' command to check.
