Safe battery handling is crucial for drone operation. The FAA provides guidelines for battery safety:
Important safety practices: Never charge unattended, maintain proper ventilation, and use designated LiPo chargers only. If a battery starts swelling, smoking, or feels hot, move it to a fire-safe area immediately. Always have a class D fire extinguisher nearby during charging. For transport, check airline regulations as most require batteries in carry-on luggage with terminals protected.
