Well, my batteries came in today, not sure if they're factory batteries or not, the label on them is a little different from my factory battery, but they were in what looked like a DJI factory box so... I don't know.
I did have a problem with the seller though... He told me he would sell them to me for 105 each, free shipping. I bought and paid for 3 with PayPal. When they arrived, it turns out he had accidentally marked the weight wrong when ordering the shipping label, so the post office charged me another 12.20 for shipping! I told him about it and he said he must have made a mistake and would give me 12.00 off my next order.
I asked him just to refund me back 12.00 but he wouldn't do it. I told him I wouldn't be ordering from him again and that I would spread the word on here. If someone wants to try to get my 12.00 credit let me know, and you can have it, but I won't order from him again. My brother was going to get another 3 batteries for his, but will look for someone else as well.
