I have a 3s 2200mah 30a discharge lipo and a 2s 1750mah 25a lipo for my quad and 2 planes. These are the only two batteries I've ever had, as I'm not that deeply involved in the RC hobby. I haven't used them in a year because I don't have a liscence yet and biking to the nearest field with an FT 3D strapped to my back would be highly unwieldy. The voltages are all balanced across cells, sitting at around 3.87v for each battery. Neither shows any signs of ballooning, but of course it never hurts to be safe. Would it be dumb to run these batteries after them sitting for so long?
