I am trying to set up a Cube Red, and am having trouble getting the battery monitor right. I am set up with a Mauch BEC and current sensor with a 3s 5200mAh battery. On the primary, it works just fine. I can see accurate voltage and current readings on the HUD in Mission Planner. When I connect to the secondary chip (which my TCP connection does automatically and I have not figured out how to fix that, advice is welcome), the battery readings are way off. Like 0V total and +30A over the correct reading. The parameters between the two chips are the same. Why might this be happening? I am new to the world of two processors in one so forgive my ignorance with this.
