Okay. SO, an update. I'm now just waiting for my order of parts to come in so I can start putting this thing together. I decided to use a traditional switch, opting for the FDV Low-Profile switch. Got some 14GA wire, a Keystone 1048 sled, FDV V4 510, IRLB3034 MOSFET, 15A fuses, 15kΩ resistors, a Voltmeter, some magnets, some epoxy, and some other things I'm forgetting right now. I'm thinking that I'm going to just do a parallel build, instead of my initial idea of going series. Not sure why I chose this, as I honestly have no idea what the difference is, since apparently battery life is the same no matter what. The only thing I can gather is that a series build has more voltage. I think I might be too stupid for this, lol.
