I have developed a BMS for these modules, allowing them to be monitored, balanced, and connected to a CAN bus. It was necessary to develop custom hardware to communicate with them. Full open source hardware, software, and documentation can be found here: https://github.com/catphish/lg-daisychain/
The module supports the following functionality:
* Automatic balancing of all cells in the chain
* Pack and cell voltages transmitted on CAN bus
* Temperatures transmitted via CAN bus
* Balancing target can be set via CAN or standalone
Some photos of the batteries and my BMS module:

I don't know how many of these batteries exist, or whether there are other batteries out there using this same chip, but hopefully this will be useful. I will certainly be using it in my own projects.
I have also built a version of SimpBMS that works with these modules. This is only very lightly tested, and probably requires more work, but could be useful for anyone wishing to integrate these batteries: https://github.com/catphish/LG-BMS
