Seems to me like there may be some safety and liability issues with a homemade/lumber battery box. Maybe I'm getting gun shy after hearing sue stories. Is this a common practice? I did some looking and there really isn't a single box that would work for this system so it would've taken two boxes to do it, so that could be why they did it.<br>
