Industrial Rechargeable Li-Po

Lithium Polymer (Li-Po) is a very low profile battery resembling the profile of a credit card. It is packaged in a “Foil” type casing and is available in a variety of different sizes.
Manufacturers are not bound by standard cell formats and sizes. With sufficient volume, just about any reasonable size can be manufactured.
Li-On batteries are relatively safe and have a higher resistance to overcharge. In addition, due to their “Foil” type packaging, they are less inclined to explode in cases of abuse or failure.
