Tamiya Connector Pack, Female
This style of high-current connector is commonly used with the 7.2V sub-C battery packs that power many RC cars. The connector is keyed so that power cannot be reversed, and a latch secures the connection so that it will not become disconnected. You can use a crimping tool to attach these connectors to your own 14- to 20-AWG wires. This pack contains enough housings and crimp pins (including two spare pins) for 3 female connectors.
