Replace battery Chuwi Hi 10 Air

Hi, I want to replace my Chuwi Hi10 Air battery. Anyone know where I can buy this battery?

Write to and, if you do not get the replacement there, you will have to find it in Ali Express. You can write here again in case you need help locating it

About Ali Express is what I’m about to look for but I don’t know which model. Search result for Chuwi Hi 10 Air battery doesn’t produce much info.
