Still dont get it why gov regulators allows LiPo on planes!
If you ban LiPo on planes, you ban anyone carrying a phone, tablet, or notebook. The kind of thing every business traveller needs to make travel work for them. Its not feasible to ban them. They have to be managed. There are controls on batteries in checked in luggage. They try to stop people travelling with large amounts of LiPo batteries.
Not just business travelers. I'd estimate that on a typical flight, greater than 100%* of passengers have mobile phones. It's not as though having a mobile phone is some kind of an extravagance these days, they're a basic utility for everyone -- it boggles my mind that anyone would think that categorically banning lithium-ion batteries on airplanes is a sensible idea, never mind a practical one. (And before they say "well just take another mode of transport!" -- there are routes that are either nearly impossible to do by any other mode of transport, or categorically impossible. And since not every flight taken is a vacation trip, "just don't travel" is not a useful option, either.)
We'd also have to ban Bluetooth earphones, e-readers, digital cameras, vape devices, power banks, flashlights, and other obviously useful things. Oh, and we'd have to ban the Boeing 787 and Airbus A350, too.
*Because many people have two phones, especially business travelers.
