You get two color coded plastic caps, 2 parallel connector plates with 16 neodymium magnets, three nylon bolts, six washers, three nuts, 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.
