Car Audio Electrical Maxwell Ultracapacitors versus Drycell Battery

As with most things electronic, car audio evolves. All the rave now (due to some rule changes in major car audio leagues) is ultracapacitors. Make a bank and supposedly they are way better than drycell batteries. So i bought some and was struck immediately by their size and weight. 12 fit in a large flatrate box! so here's a vid to show the size and weight difference. enjoy!
