I just ordered a Summit battery relocation kit. Since my donut doesn't fit over my front brakes anyway, I've decided to put my batery in the spare tire compartment. The kit comes with a plastic box and everything you need to secure the bastid, and plenty of cable.

Nothing too exciting... I figure it should be a snap to install, but if any of you who have moved your battery have any words of wisdom to offer, please feel free to chime in.
