This is the 12P case that is triple split to create a 4P3S battery. This battery has 9 volts and can be connected in series with other 4P3S batteries.
You get two color coded plastic caps, 2 parallel connector plates with 24 neodymium magnets, 5 nylon bolts, 9 washers, 5 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.
