Snap is recalling and refunding every drone it ever sold::Snap is recalling every one of its Pixy drones because their batteries pose a fire hazard. Yes, the entire drone is being recalled, not just the removable battery. Snap discontinued the drone just months after release.
Using proprietary batteries is bad, and this is one reason why. A 14500 (AA-size Li-ion) probably would have worked this application and slightly exceeds their battery’s 3.3 Wh capacity.
