I run the Interstate GC2-XHD. Rated at 232ah each, retail was listed at $150ish each if I recall and the guy at the counter discounted them to $115 for me. I run 4 of them for the stereo bank, 464ah total for that bank. What you posted is correct Trayson, you cant sum the ah of the 6v like you would using 12v, but the abuse these deep cycle 6v can take is a great advantage it seems.
