I have a Leaf battery pack in my shop and a couple modules sitting on this table. This info is accurate.
I noticed one of the suggestions early in this thread was to use an arduino based system. If you're not into building one from scratch, but would like some control over the programming, you might consider the system offered by Linear Technology. It's actually not really a "product" but more of a demo system for companies developing a BMS. I'm going to assume you mean 9 modules, which would be looked at like 18 cells from this system's perspective. ( the 2 parallel cells would be seen as one by the BMS ) Each LT IC is designed to manage 12 cells. It uses a serial or parallel communication bus to a central "Linduino" ( Arduino ) communication microcontroller. The Linduino can then communicate with a USB to just about any PC.

The specs say:
60a/h rated - 7.6V - 500 W/h - max continuous power 1875W or 240A
Peak current 540A
Measured 62Ah from 4.2 to 3V, and 64Ah (4.2-2.5V)
Maximum voltage 4.2V per cell / 8.4V per battery
Average voltage 3.8V
90% of the capacity voltage - 4.2-3.7V
Each module contains 4 prismatic cells (see photos), connected 2S2P
Each prismatic battery has rated capacity 30A/h and 3.8V nominal voltage
