Would this bms work and support the discharge side ? https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com/ulk/itm/192702426670

I don't think that BMS will work with your system. I am also making a build with Nissan Leaf batteries; each Nissan module is rated at around 8 volts. That BMS has a battery voltage detection range of 1-5V so its a little too low to detect a leaf module. Maybe it could work if you set it up to each cell in the module but i think your best bet is to find something similar to this but with a little higher voltage detection. If you find something please let me know though I'm also in the market for a BMS for Leaf batteries! Ill msg here if I find anything as well.

Ahh okay I understand how this works now. Thank you for the clarification on the use of the center tap. I've been doing research on how all of this works from home so I appreciate the knowledge. Its gonna be put to good use!
