Right now I have 2 12-volt deep cycle batteries to power my 24-volt Ultrex. I like having 2 separate 12-volt batteries as this lets me just use one 12-volt to power my twin Minn Kota trolling motors I'm using as brakes for Livescope fishing while still supplying 24 volts to my Ultrex. I wouldn't be able to do this with a dedicated 24-volt battery. I do have a 100 AH lithium battery to supply my 2 1222s and black boxes and my 943 XSV in the dash.
