No, No, You miss the point! The leads (the wires, not the plugs) on the original batt and the 3-in-1 board are the same size ( hence, your almost unfortunate experience). My point is the difference in the size of the battery leads ( the power source) and the Main Motor (the largest power consumer). Everything I learned in school (20 or more years ago, ugh!) says the bat leads should be at least as large as the motor leads!
