Hello, the title is the question. I've read that it can very from battery to battery. With battery lifespan, I don't mean how long it can sta in the air, or the flight time per session, I really mean the excepted lifespan of the battery before I have to change it. Since they are expensive it would be great to know before buying a Phantom, if buying one. My small lipos seems to last many many flights. SO if anyone knows, if it is possible, how many flights or how long time can you keep the same battery before chaning it completely?
