Getting into FPV drones was super interesting because battery tech plays a huge part in the hobby. Rather than voltages, everything is normalized to number of LiPo cells in series, e.g. 1S, 2S, 4S. Drone accessories also accept a super wide voltage range so they can be mostly powered by whatever battery packs you have laying around (excepting support for 6S, which is kinda rare). However moving past drones, you'll start seeing other battery chemistries with different voltage ranges. Li-Ion can be discharged further than LiPo. LiFePO4 tops out at 3.6V, rather 4.2V. And so on.
