Building A Custom Lithium Battery

Looks nice! I’m still learning so might be a stupid question, but what size wire is used for negative terminal? Wondering what the current carrying capacity is.

Not stupid at all. Getting the right sized wire makes a world of difference. We use 1/0 gauge wire to connect the batteries to each other and the busbars. That's a good reminder, though, I should make a video of how the whole system comes together.

Not bad!
