All this info has come from the guys at Park Lane, just spoke to them again and they have re stated that attaching anything directly to the battery will invalidate the warranty.
Ask them for it in writing then, and where exactly it says that.
AFAIK they would have to show the modification caused the event, eg different exhaust with only headers causes the valves to burn out, you're on your own. Paint starts to peel on the beak, no problem.
BTW if they say it'll make the battery fail, then the software etc seems to do quite a good job on its own on some 1200's
