Not only did I save the weight of the battery, I saved about 20# of cable by mounting the battery a foot away from the starter on the inside of the frame rail, instead of in the trunk. The NHRA mandated battery cut off switch is right there too, with the lever of it on the floor inside the car where I can reach it if I forget to turn it on. A 3/8" x .030" wall stainless steel tube runs from the lever, back through the trunk and out the back of the car as a remote control for the switch. That is much lighter than a Morse cable, it only weight a pound.
