I have 20 packs as shown in pics. Each pack has 27 Panasonic NCR18650 cells. These packs are used. $33.75 per pack ($1.25/cell). We can ship. USA only.

What were these packs from? What is the cell arrangement?

I am not 100% sure of the origin. I do believe they were for an EV that never went to market based on the other packs I have here. See posted pic.

Arrangement is:3S9P

Uses a Texas Instruments battery monitor, the BQ20Z95 (http://www.ti.com/lit/ds/symlink/bq20z95.pdf), so it should be easy enough to talk to it via SMBus.

The bq20z95 SBS-compliant gas gauge and protection IC is a single IC solution designed for battery-pack or in-system installation. The bq20z95 measures and maintains an accurate record of available charge in Li-Ion or Li-Polymer batteries using its integrated high-performance analog peripherals, monitors capacity change, battery impedance, open-circuit voltage, and other critical parameters of the battery pack as well and reports the information to the system host controller over a serial-communication bus.
....
The bq20z95 uses SMBus v1.1 with MASTER mode and package error checking (PEC) options per the SBS specification
