What is the rig setup? 40A is a lot. But I'm running the lower lc mostly. But even 4 1250kv didn't draw more than the limit.
Not sure if the issue is the way you have it hooked up, or if it's the taranis settings. You programmed it the way I listed above?
thats been working for me on 4 builds now. Same setup on page 12, always run from battery to PDB. Same as yours, voltage from the little cell checker type sensor and consumption from the current sensor.
