Presumably it depends on the total mAh of the battery shipment.

mAh is the milliamphours.
It is a measure of the energy stored in the battery.
The link ENAUD posted mentioned 30% max charge on international(as I recall) and capacity was mentioned as a factor.

After reading that(and judging from the actual transcript of 2012 law) it appears capacity, according the law, is based on watts-hours. I don't know why they decided to use this standard when the battery industry has clearly established mah.

The two are mathematically interchangeable via ohms law, but our beloved mod batteries are labeled as mah. It's not likely your average mail clerk has even seen an Ohm's wheel diagram; let alone understand how to use one.

If I didn't know better I'd think they intentionally complicated this law for future clarification. Legislative 'busy work' and meddling. Or have I just misinterpreted?

watt-hours is a universal .. actual measure of energy.
amp-hours is what is usually quoted on 18650 lithium.
I suppose the reason for using amp-hours (or milliamphours) is just historyonics.

2 batts

Both 3500 mah

One is 3.7V

One 18.5V

One is 5 times the size, 5 times the cells, 5 times the watt hours, 5 times as dangerous and 5 times the chances for failure.

These rules only apply to passenger planes, you can still ship them in any qty on cargo planes.

Only under Containment regulations. - i.e. Special Containers and Packing.
Lithium Batteries are Classified Hazardous and that Does Not change.

One would be Lucky to find any Non-Courier(DHL-FedEx) Cargo plane willing to accept a single package with 2-3 Lithium 18650 Batteries for transport.

Professional International Couriers charge a Premium for Transport of Hazardous materials and Follow international guide lines to the letter. Their livelihood depends on it.
