The tiny 400mAh #LithiumPolymer#battery in this cheap #Bluetooth#speaker turned into a puffed up pillow. I've replaced it with a 350mAh one I salvaged from a single-use disposable #vape device. In spite of the lower capacity, it is significantly larger than the original battery. Hope it can still fit in the available space.
Also fitted a JST connector to the speaker wires in case I need to disassemble again for a future #repair.
