No voltage sense wire is going to make up for not getting sufficient voltage at rated amperage to the batteries due to inadequate wire between the controller and the batteries.
20 feet of AWG 6 between the controller and the batteries with 400 watts of solar is a failed system, period.
Bottom line is that the OP has wire he has to live with, presently. It may be that a controller with good set point variability gets him healthy batteries.
