BMS integration if you want to use Tesla Battery Modules for Solar or other backup systems. The integration is extremely simple and uses the existing BMB boards on the individual modules. This BMS integration is also used for testing the complete Model S/X battery pack and provides detailed information about voltages and delta of cells within the modules. It can read a single module or the entire string of 16 modules. It can allow you to balance cells that have high delta if you are trying to repair a battery pack with a high delta.
