Get organized and just start reading and researching if your going to build your own pack. I was thinking the same thing wishing there was a step by step when I put together this build thread. Its not perfect and here's a lot of other ways to build lithium packs out there but here's one option for you. I strongly recommend you have a thorough understanding before you get started.
