Hello, I need some help. So right now i have a saturn ion and just ran some 1/0 gauge wire to the trunk of my car doing the big 3. I was wondering if i can hook up my xs 1200 battery in parallel, too my starting durlast battery, with each battery receiving its own cable from the alternator? would this work? Since both batterys are in the trunk i can ground them to the same point. I have no idea what to do??
