What does AWG or gauge mean when referring to wire?

American Wire Gauge or AWG for short is a measurement for diameter of wire. The smaller the number, the larger the diameter of wire is. For example, the thickest wire we offer is 4awg and the smallest diameter is 22awg. The higher the amps your motor needs to pull from the battery, the thicker the wire gauge needs to be to transfer that power efficiently from the battery to the motor.
