NBv4 Wiring and Best Practices

[reytheist]

Building my first saber. I'm going to be using a nano biscotte v4 with a GGW tri-LED (to try to do white FoC), and a removable 18650 cell. Here's the diagram I cam up with, which includes my math.

1. Is there anything that I missed or overlooked?
2. Should I be wiring the illumated switch LED to the battery negative or to the main LED pad? Would that be the difference between always on and on when activated?
3. There are some places where I have four wires soldered in to one. Should I solder it separately at a different position?
