You get two color coded plastic caps, 2 parallel connector plates with 32 neodymium magnets, seven nylon bolts, seven washers, seven nuts, two yellow magnet retainers and a front to back connector. You get enough ring terminals to connect the balance and power wires. The included series connector is used for connecting the blocks to each other. Use the side to side connectors if you want to mount the batteries to a flat surface, making a power wall.
