Search Google and check out Mega Fuses, you can also use them instead of fusible links, and I believe you can get anywhere from around 60A - 250A so you can power your main fuse panel(s), and even your starter motor main cable. They use these a lot on newer cars, and with main buss plates right on top of battery.
I plan to use them similar to a friend's setup when I relocate my battery to trunk. He's just got one main, but I plan to use a few different sizes.
