WTB: Racing battery - lightweight
 

So I failed tech at the drags yesterday in my 240 because of my battery relocation. There are a ton of requirements to make it all safe and I just don't want to hassle with it. The guy said the easiest way would be to just put a little battery in the engine bay.
I looked at ebay and they're like 120.
I don't want to pay 120 for a battery

Does anyone have one of the lightweight little batteries for sale?

I'm in the bay area.
