I am building a flight box similar to those on the Ultimate flight box thread. I need both 12 and 24 volt connections. 12 going to a standard control panel and 24 going to a Dynatron starter. I was wondering if what I am thinking will work. See attachment. Two batteries daisy chained together for the 24 volt connection and then tie the control pannel off of one of the batteries. Seems like it should work. Any help would be greatly apprciated.
