>Where do I get components and lab equipment from?
ladyada.net/library/procure/hobbyist.html
Search the web for "hobbyist electronics sources" to find plenty.
In the US and elsewhere, mouser.com, digikey.com, arrow.com, newark.com are full-line distributors that entertain small orders.

CircuitJS (quick, dirty, interactive)

>What software should I use to layout boards?
Circuit Wizard
ExpressPCB
EAGLE
KiCad

>Q1. Lithium batteries
Will explode if you abuse them. Read and understand all relevant datasheets and be prepared for catastrophe. See
batteryuniversity.com/learn/
>Q2. My circuit doesn't work. Halp?
Check wiring, soldering, part pinouts, and board artwork if applicable, then post schematic.

That's the beauty of inductors: in the moment of switch-off, the current is the same as it was before. It just keeps on flowing no matter what because the stored energy has to go somewhere and it definitely will find a path.

The good thing is that your contraption will not draw 210A for long (if ever) because 20V*200A=4kW and 20V*6Ah=120Wh which means 120Wh/4000W=108s. Given the loss of capacity at that load level I'll give it less than a minute. Just enjoy the seductive fragrance called Fleur d'Ampère and let it expire naturally. What was the internal resistance of the lipo again? Enough for another kilowatt?

You cannot simulate ignorance. Just solder the red to the black wire, watch them explode and collect your Darwin Award.
