I know this has been discussed many times, and I've read the threads, but I still can't decide whether I need to add a second battery. I have a 55 amp alternator and a group 34 Optima blue top (the deep cycle one). I have a stereo that's 1040 watts in full song, and a ballast system with 4 ballast puppy's. We are always rushed, and our usual program is to start the boat, start the pumps, turn off the pumps 3000 pounds later, turn on the stereo, wakeboard, turn off the stereo, hit the pumps to empty, turn off the boat, and go home. So, my question is, can one battery keep up with all that? I've never had any problems in the past, but I added 550 watts to the stereo this off season, which has me concerned. I just don't want to be going down the creek with my gauges dimming to the beat of 50 cent. I've never put the battery on a charger afterwards but I certainly could. As always, thanks so much for any insight.
