Ill probably go to a competition or two, im atleast going to see how it runs without a second battery before i do it. But the big reason im running two instead of just swapping mine with a nicer one is why have one when you can have two and having a second remote battery in the trunk will make wiring everything alot easier plus itll give me more access to the fuses.

Should i run a fuse between the main battery to the second battery by the way?
