The better ones use a switch mode regulator so they operate over a wide range of input voltages and output voltages. The manual should tell you what range of output voltages it will handle, and what the optimum range is. If not, contact the manufacturer. You may have to connect the batteries in series-parallel for 24 volts. Why are they connected in series? .<br><b>References : </b><br> Read the manual for your controller, which I assume is a charge controller.
