You get two color coded plastic caps, 2 parallel connector plates with 8 neodymium magnets, one nylon bolt, two washers, one nut, two yellow magnet retainers, and a front to back connector. You get enough ring terminals to connect the balance and power wires. The “connectors” are used for connecting the blocks to each other. Front to back connectors are normal and are pictured. Use the side to side connectors if you want to mount the batteries to a flat surface, making a power wall.
