We are the distributor of mp3p for many korean manufacturers in Taiwan. Acquiring batteries from them is time consuming. Therefore we have decided to get the batteries ourselves. We are looking two sizes of li-polymer battery, both with 3.7v 480~500mah but in different sizes.
Size 1:46mm*17mm*4mm(height*width*thickness)
Size 2:40mm*30mm*4mm(height*width*thickness)
