Does anyone else have this issue? Before our state tournament, we had practiced over and over on our home field for up to 10 minutes at a time with the same batteries and never had stalling problems. It was only plugged into the field controllers at the tournament where our drive stalled basically EVERY time. And we have thought about factors such as defensive play (no one ever did) and even changed our cortex out.
Oh and our drive is a 6 motor high speed hybrid base (tank in front, x drive in back). We do know that the x drive decreases torque, but don't think that it should have this much of an effect on it.
