I want to build a 20S battery out of 18650 cells that can support 200 amps continuous but cant seem to find a BMS that high. How do I manage the discharge of the cells. Is there another way to do it?

Or other similar threads that can be found in this list (most are not relevant but you can generally tell from the titles):

Maybe there should be a sticky thread for BMSes that the community has tried and their pros/cons? It's very difficult to parse the mountain of threads that may or may not have answers to questions on available BMSes.
 
Check out this site:

This BMS can be programmed and is good for 250 amps and is wifi enabled! Of course you will be asked to pay an awful lot for those features, but that is one option that might work for you.

Good luck.
