The CC 6.5mm bullet plugs are rated to ~200 amps. It is like putting a bigger pipe in your house to let more water in. It's possible to flow extra water through your smaller pipe but it will strain the system more, the larger pipe (bigger plugs) allow for more flow. Connectors aren't a huge deal with trucks, 5.5mm plugs are typically plenty for the motors and Deans can handle the batteries fine. In higher draw applications like a boat you really need larger connectors, I've seen Deans connectors literally melt together in a boat.
