EcoWorthy 12.8V 150Ah definitely shuts off (LVDC), I would expect the same from an equally high[er]-end product in their catalog such as the 25.6V 100Ah? Opening up mine didn't seem to be pouch cells, but I didn't take it apart more than just taking the top cover off (all-metal case), I can post a pic if anyone is interested.I think DC HOUSE are rebranded Eco-Worthy units and I watched a teardown on the tube of their 12v 100ah units, Build quality seemed pretty good for such a low price but if my memory serves me right it didn't shut off during 0.2C discharge at 10V but didn't go into limp mode.
