Hello to all I am new to FE boats and gear,so bear with my questions please. I am wondering why there is such an advantage to using the higher mm connectors on motor and ESC to battery. I am going to install a Aquacraft UL 1 motor in my boat, The question is it comes with 4 mm connectors but i am being told to use 6 mm connectors. The wire size on the motor is smaller than the ESC so what is the advantage to the 6 mm connectors over the 4mm if the wire size is related to power. Also due to the smaller wire size on the larger connector does this create a problem with soldering as this is my first time soldering. Thank You Jerry
