I ordered a spare battery for my Vision from a seperate dealer on amazon than I bought my phantom from. It was $129 bucks. When I was in the DJI assistant software a pop up came up that said it was not a smart battery. I am looking on amazon at smart batteries and I see price fluctuations for the smart battery of anywhere from 175 to 250 for the same MAH batteries. Whats is the difference? Do you recommend I send back the one I have and buy a smart battery? What exactly do the smart batteries do that others dont?
