So I just flew from Boston to Kentucky this week and the folks at Logan didn't really question the 4 Phase batteries that I had, 3 rechargeable H2 grips or the 1 battery geek 130Wh battery. But they did TAKE my Lead acid Bose battery $150.00 from the checked luggage. I have traveled with this for 4 years. They left a slip saying that the pelican case was searched, as was all the other bags this trip. There was no mention they the took the battery. The good news is that I can buy a new battery for $150. Thanks TSA!
Happy Travels,
Ken
