ESC Electronic Speed Controller with Cut Off Switch for AGM and LiFePO Batteries

In this video, I illustrate a method to build an ESC for use with a 12V trolling motor powered by either an AGM or LiFePO battery. This build includes a modified servo controller with a center detent potentiometer, on/off switch, and a PWC cut off (kill) switch. The completed ESC is mounted in a waterproof electronics project box.
