This paper aims to clarify the behavior and damage conditions of batteries when multi-rotor unmanned aerial vehicles (drones) in horizontal flight collide with a structure to obtain the engineering knowledge that serves to consider the method of the safety performance evaluation of drone batteries in the collision. Drones with maximum takeoff weight of 15. 5 kg. 24. https://www.ealisboa.com/top-offer-Birkenstock-Arizona-Eva-Beetroot-Purple-best-save/
