A solid state speed controller tho allows the whole pack to be wired at a higher voltage, to get the same number of watts out of a higher voltage pack you don't have to draw as many amps, so right there you can use smaller gauge wire and often times the pre controller increase in efficiency makes up for the losses inside the speed controller, the batteries also see gentler use so they last longer as well, I've had my solid state speed controller installed for about two weeks now and even tho my batteries are a year older then they were last year my state of charge when I reach work is higher then at any point last year and I don't feel like my motor is trying to rip my car in half any more.
