Alert: The "Official" Viltrox store at AliExpress is a fake, Part 1 (First Battery)

purchase 2 brand new battery from the "declared Official" Store of Viltrox is a fake. These batteries claims to be from Viltrox. After I email Viltrox at [e-mail], they told me they don't have an official store at Aliexpress. I then ask them where is their official store, and they told me their official store is at Amazon
I went to Amazon, Viltrox doesn't even make any compatible battery for Canon. So there is no way this Aliexpress is selling a real Viltrox battery for Canon. In summary, this store is a fake
As to the battery strength, notice how fast they drop with only a few dozen photo / video taken. And how fast it drops after the battery is below 50%, my 10 year old Canon battery drops slower than that.
At shutter count of 2, it sits at 83%. At Shutter count of 23, it drops to 43%, and just spending less than 1 min. of showing the display of these 21 photo / video, the battery drop to 38%.
Later on, when the shutter was at 41, it sits at 25%, and yet, when I take only 9 more photo/video, it strangely nose dive to 8% at a shutter count of 50
