@Nooby and @Harryssss Can you guys check my parts list, if anything is missing.
I also have 2 questions.
What thickness wire do you guys use to connect to the battery. Will 1.5mm wire be thick enough, or should I go 2.5mm.
What do you guys use for the battery positive connector?
I'm jumping in here; for pure mechanical use solid copper wire, and if you put an electronic regulated module in, use stranded wire because of the high switching frequency. Use the thickest wire you are comfortable with - to limit voltage drop. For wire thickness you can use the following guideline:
0.1mm per 1A, i.e 15A x 0.1 = 1.5mm
