Switched everything over to 6.5 bullet connectors and the problem persisted. Go WOT and the truck will stutter and the front end looks like it's being pulled down. I checked the Castle Link again and saw that the "Starup Power" setting was set to "Medium" for "High Quality" batteries. As we all already know and azjc keeps pointing out, Max Amps batteries are over rated. I'm recharging at the moment, but I'll try this setting at "Low" and see how it goes.
