Beginning on April 1st, 2016 there will be major changes taking effect under the International Air Transport Association’s (IATA) 57th Edition of the Dangerous Goods Regulations (DGR).
There are four new restrictions that will apply to shipments of lithium-ion batteries shipped alone by air under UN 3480:

Packages containing only lithium-ion batteries (no equipment) will be permitted on cargo aircraft only. This requires all packages of these types going by air to include the “Cargo Aircraft Only” label.
All packages containing lithium-ion batteries must be shipped at no more than 30% state of charge.
Shippers may offer only one package per consignment of “small” lithium-ion cells or batteries (i.e., = 2 Wh or = 100 Wh, respectively) prepared in accordance with Section II of the applicable IATA packing instruction (i.e., PI 965). In addition, no more than one of these packages can be in a single overpack. The overpack must include the lithium battery handling label.
The package of excepted “small” lithium-ion batteries must be offered separately from all other cargo and may not be pre-loaded in a Unit Load Device (ULD).
