Last summer I tried my hand at building a drone. I learned a lot about drone battery use, and eventually settled on a 14.8V (4*3.7V), 4000mAh Lithium Polymer (LiPo) battery with a 10C rating
In my last job we occasionally would use the lead acid batteries you can get at most hardware stores. The standard size we used was 12V, 7Ah, C5 capacity.
I also often use CR2023 coin cell batteries that provide 3V and around .2 mAh. I’m not sure of the C rating.
