If a website lists grams of Lithium, use this formula (source):
Equivalent Lithium Content (ELC). ELC is a measure by which lithium ion batteries are classified.
8 grams of equivalent lithium content are equal to about 100 watt-hours. 25 grams of equivalent lithium content are equal to about 300 watt-hours.
You can arrive at the number of watt-hours your battery provides if you know how many milliamp hours and volts your battery provides: mAh/1000 x V = wh
Some more information here from Thailand, as of Jan 2015 (sorry, a bit shaky)L Essentially, anything above 32'000 mAh is forbidden, below that and above 20'000 mAh is limited to 2 per person, below that there are no limits, but all only in hand luggage.
