A question that we get often is “Are mobility scooter batteries allowed on air planes even through they’re made of lithium?”. Lithium batteries are sometimes not permitted but it all depends on the air line rules and regulations. It’s best to be aware of federal laws and the airline rules to ensure you don’t end up getting stuck at the airport. FAA states that you can travel with a battery powered wheelchair or mobility scooter that doesn’t exceed 300 Watt hours (Wh) or 25 grams equivalent lithium content (ELC).
