Hi Bryan,
Those type of batteries typically require a network and internet connection to work, they don't work properly on there own for a standalone system, also if they have been siting for a long time left uncharged the BMS will drain the cells to Zero = STUFFED , not seen this happen with other BMS and battery builds, the cells alone can sit for years untouched without issue.
I have one of the Black case sonnens 2.5Kwh, they are also 15s...,pouch cells in 15s 2p arrangement, net even 16s like others.
Interesting to watch..........Save your money for something else.
