I ordered a spare battery and prop protector for my Mavic Mini through amazon back in early December.... this is supposed to be sold by someplace called HuaYe Tech in China.... the only tracking information I can get is that it shipped from one place in China to another one through something called 4PX on Dec 19th and that the scheduled delivery is any where from Jan 6th to Jan 31st... Is there any where else on the planet that I might get a battery quicker? It seems DJI doesn't have them either...
