I have a robot that keeps stalking out its motors after about of 45 seconds of use, letting it rest for a few seconds will usually enable it to keep operating but it has tripped and completely reset the cortex a few times. I'm running 11 motors (4drive, 6lift, and 1claw) on already two power expanders and three batteries. The motors are split evenly 6 on ports 1-5 and 5 on ports 6-10. To me having two power expanders seems like it should be more than enough to handle 11 motors without tripping a circuit. Mabye i'm wrong and just have to add more power expanders but that dosn't seem right. Help?
