So I kinda forgot about my drone over the winter and left the batteries completely dead for like 6 months. Now, no surprise, they won’t charge at all. I’m guessing they’re done for, but is there anything I can do to maybe save them or at least make back some of the loss?
Also, are there any good places to get cheaper batteries that aren’t sketchy knock-offs? Like maybe refurbished ones? And if so, are refurbished batteries even worth trying?
