Nissan part numbers:
293A0-9RB3A (24 kWh)
293A0-4NR5B (30 kWh, different busbar/harness pinout)
This is sort of a niche topic, but may be of some interest to the people (re)building packs who don't already have a donor pack to hack. For the past couple years, it was fairly simple to acquire a LEAF LBC/BMS on eBay for about $50-60. For a piece of hardware that's certified (somewhere) for 400V/96S, and features integrated CAN, balancing, pairing, temperature sensing, and voltage/charge monitoring on all cells, it was a real deal. That supply seems to now be exhausted.
Today, the lowest online price for Leaf BMS/LBC modules is around $350. If anyone is building "feature complete" aftermarket packs, they'll need to find alternative sources (maybe get in touch with Calsonic Kansei Corp) or pay fairly extravagant factory prices.
For reference, one of the last official suppliers is here:
