Wire Dimensions

Wire Dimensions

The AX1500 uses screw terminals for the power connections to the batteries and motors. These connectors are rated to support the controller’s maximum specified current. It is rec- ommended that you use AWG12 wire for all power connections to ground, batteries and motors. The Power Control wire and its return Ground may be much thinner as they will never carry current in excess of a couple of milliamperes.

Weight

Controller weight is 4.0oz (120g)
