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.

Leaf packs have a central "tap" terminal which enables BMS connection to each internal cell (actually a pair of cells in parallel) - so a BMS with a working range of only 5v will be suitable for use with Leaf packs.

All of the BMS that I know of on the market are made to be attached to each cell, not each Leaf Module.

There are 3 taps on a Leaf cell. B-, B+ and a center tap that goes to the connection inside between the two cell groups. This allows you to tap off each cell and use a standard BMS.

I'd never suggest someone monitor at the module-level. Always monitor at the cell-level.

Background on me, since you're new to the forum: I've been selling BMS for years so I know a lot of the vendors of BMS, and how they work and are configured. Elithion, Orion, Zeva and have built multiple designs of a BMS.

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!
