Good way to go from 72v to 48v temporarily
I would like to have my xb-600 be able to go back to 48v temporarily at times. I would like to wire it in such a way that I could use a switch or a relay that would disconnect the 2 additional batteries without physically unhooking them. I guess I could use a spdt switch to interrupt the additional batteries. I was hoping to hear of some other ways to do this with a relay. Any suggestions?
