I installed a BBS02 on a customers bike a few weeks ago that he had gotten from this company. The 48v 10ah Shark battery came in a Priority Mail box uncertified to UN 3480 with Class 9 Hazard labels. "The penalties for failing to properly package or properly offer for transport a lithium battery can carry fines of up to $55,000 dollars per package per day. This is for accidental violation of the rules where there is no intent to “wilfully” violate the requirements.Feb 25, 2013."
Not to mention when asked at the PO if there was anything liquid, fragile or potentially hazardous and not declaring it as such is also a federal crime.
Just saying.....
