Guys need some major help Took my Finow x5 smartwatch to bits today and a big spark came from the battery, luckily the battery was completely out of the watch when this happened so I know the board is going to be ok, does anyone know basically where I can get a replacement Finow X5 battery from it’s the round coin shaped one.

Thanks Jay
