Hello guys
I went to the track and they were giving me a hard time over running my car with the battery in the trunk. ( No way in hell am i driling hole in the rear bumper to accomodate a kill switch )

Does anyone sell or know where I can purchased a very small battery?

Something relatively small that is about 1/2 the size of the battery tray.

let me know…
