Have any of you installed Needswings' Shuriken battery kit?
In my car, after tightening down the battery holder on top, the battery is still really loose. There's no way I could pass tech inspection with it that loose. In fact, I took it out because it's just too unsafe for driving around town. Has any one solved this or have any ideas how I could make it more secure?

If the photo's came through, you can see how much room there is all the way around the battery.
