Auxiliary Battery & Battery Bulkhead Connectors

Using an Auxiliary battery to start a racecar with a total-loss electrical system will save the on-board battery for the race or for restarting after a spin. Our battery connectors make it quick and easy to plug in the jumper battery on the grid.

All of our Auxiliary Battery Connectors are grey. Each connector half will work on either the car or the battery side.
