RCPRESS tip: battery to be carried onboard a flight

Generally, the restriction is spare lithium batteries must be under 100 Watt-hour (Wh) TOTAL per person. “Spare” means removable.

For RC batteries that are measured in mah, 1000 mah = 1ah amp hour .

Watt-hours = amp-hours x volts.

So, a 2S 2000 mah pack = 2 x 7.4 = 14.8 Wh per pack.

Each battery needs to be individually pack with terminals sealed with tape. The product label must be intact.
