I bought similar from BLS (aliexpress): 16pcs 130Ah to build a 48v battery. As written above they are shipped in a great package, very well covered, each in a box with foam, and the boxes additional in a foam in the package.
My arrived well balanced, but I did an additional bottom balance (around 2.8/2.9V).
I use them at home with my solar, not sure if I would recommend them for outdoor like marine or RV. They have a alu case with this blue foil, but if you need to pull them in/out I assume the foil does not live long.
I have no capacity meter but comparing the kWh of my charger without a load on an empty battery or vice versa just discharging a full one with constant power without charging they provide roughly the capacity I would expect.
What I like is that the buses are a bit longer as required, so I can arrange the cells in a zigzag with better air flow between each other.
