Can we use a different battery in the iNew v3?

The video with the soldering iron seems like the easiest way to do it. I am speaking trying to get a supplier that will modify the THL W8 battery according to that video so that we can buy it directly and it will fit the phone. What do you think?

But the original battery on almost any supplier I checked is different than this BLACK one on the video. The one I bought with blue and grey color you don't have to use a soldering icon, just a sandpaper
Maybe the black is not original, I do not know.

As I say in the video (ok, in Italian, my bad ), There are two versions of thl w8 battery. One is the normal one, with THL W8 logo and blue and grey colors, the other is the black one shown in the video. The procedure for both batteries is exactly the same. I've modified 8 batteries so far 3 of which had the THL logo.

Cheers
