Anyone with experience know if a lipo fireproof bag is necessary to store the Mavic Air’s batteries in while travelling on an airplane? My wife and I will be travelling to Iceland in a couple of weeks from Canada. First time taking a drone. The bag for 3 battery storage is around $30CDN. but if I don’t need it I’d prefer to save that $30. Would the drone carry bag that came with the fly more combo be sufficient for battery storage? I know it has to be in my carry-on. The 3 batteries combined fall well below the 100WH rule.
