The US is banning lithium batteries from cargo holds. The result will mean that all your phones, tablets, computers, music players, games consoles, and other rechargeable devices must be carried in hand luggage and tipped out onto trays to go through the metal detectors. Expect longer lines.

My son flies large RC helicopters, and the above policies are what we were told for our flight to Vegas. The helicopter would go in a checked pelican case. The batteries would go in their OEM cardboard boxes and be hand carried on the plane. We're going to ship them instead because neither of us wants to walk the agents through the math to convert Amp hours to Watt hours. (The Wh rating wasn't printed on the box.)
I think it's fire risk, not security, they are managing here. We've physically damaged (chopped with a hoe) a puffed 4 cell pack on the driveway (for Science!). The resulting fire was impressive. It absolutely could force a plane do an unscheduled landing.
