Air Transport Regulations for Lithium Batteries

1. Passenger flights regulations



  • No regulations for batteries that contain less than 2g of Lithium.


  • For device batteries, the FAA recommends a limit of 0.3 grams or less per lithium metal cell or 2.7 watt-hours per lithium ion cell.

Our 1500 mAh batteries contain 0,1g of Lithium so we are way below the limits.

Radio emission


  • Tracking devices must comply with FAA guidance 91-21-c or EASA.
  • AMC and GM to Part-CAT – Issue 2, Amendment 1 or subsequent versions of such guidance.


  • The PED must be designed with a minimum of two independent means to turn off completely, turn off cellular or mobile functions, or a combination of both when airborne.

Sigfox does not fall under the mobile/cellular or PED definition of the FAA. The device may use low-powered wireless communications during flight without the need to comply with paragraph 10.2.1. RTCA DO-363:

“Experience shows that low-power emission levels do not affect aircraft systems. The low-power emission limit is 100mW EIRP (equivalent isotropic radiated power - 100 mW is 20 dBm, so we are fine in RC1 but RC2/4 are 200 mW). Wireless communication standards which are limited to this level do not need to be analyzed for backdoor coupling.

2. Cargo regulations
