You are allowed one larger lithium ion battery installed in a device, plus up to 2 spare larger lithium ion batteries. These are in addition to any smaller lithium ion batteries. For smaller lithium ion batteries, just follow the Basic rules.
Lithium ion batteries rated over 300 watt-hours (25 g ELC) are forbidden.
\"Larger\" lithium ion batteries are rated between 100 and 300 watt-hours (8-25 g equivalent lithium content, or ELC).
The only catch is that if it is over 8 g and up to 25 g, you can travel with it, but only in carry-on baggage, not checked baggage.
