In this video, I install the Attopilot 180A voltage and current monitoring breakout board. This is a replacement for the standard power module that comes with my 3DR Pixhawk flight controller. I wan’t something that can handle more current than the stock module. I’m unsure if this is required, but it makes me feel better. : ) Plus, if I decide to move to a 6S setup, I’ll be ahead of the game.
