Good day to all. I'm working on a new version of a previous project and am looking for=20 a source of LiPo batteries. I have limited space of 45.6mm x 25mm x 5.5mm and am hoping that=20 someone can suggest a commercially-available packaged battery. I'll=20 work with a bare cell if I have to but I'd rather find a replacement=20 battery for some device where the battery doesn't exceed the dimensions abo= ve. Cell capacity should exceed 600 mAH if possible. So far, I've looked at batteries for a few cell-phones but although=20 the thickness is good, they are either too long or too wide (or=20 both). I've also looked at a battery for a GoPro Hero 3 - this=20 battery is a great size but far too thick. Since I'm being picky, I'd prefer to find a battery that uses a cell=20 manufactured in Japan. For whatever reason, I seem to be having much=20 better lifetime with Japanese cells rather than from some other country. I'm hoping that someone can suggest a device that uses a battery=20 somewhere around that size (45.6mm x 25mm x 5.5mm).
