I'm actually running the cutoff with my 4s 5000mah battery at 13.2v, and more recently at 13.6v (3.2v/cell and 3.3v/cell). I'm not sure this even tames the power output, but I can say it is too much power :). You might want to set the voltage sensor to 13.6v, since these 5000mah cells won't be hitting that voltage very often. And when they repeatedly hit that voltage, they are done.
