This is the 8P case that is split to create a 4P2S battery. This battery has 7 volts and can be connected in series with other 4P2S batteries.
You get two color coded plastic caps, 2 parallel connector plates with 16 neodymium magnets, 3 nylon bolts, 6 washers, 3 nuts, and two yellow magnet retainers.
You get enough ring terminals to connect the balance and power wires and a series connector plate for connecting to the next BatteryBloc. Use the side to side connectors if you want to mount the batteries to a flat surface, making a power wall.
