The 581013 3.7v 50mah Lithium Polymer Li ion Lipo Battery is developed for manufacturers who need reliable power solutions inside extremely compact devices.
Unlike conventional battery formats that require more installation space, this miniature pouch cell features a lightweight and flexible structure, allowing engineers to integrate rechargeable power into products with strict size limitations. Its compact dimensions make it especially suitable for applications where battery volume and weight directly affect the final product design.
With a nominal voltage of 3.7V, the battery provides consistent energy output for low-power electronic equipment. The optimized lithium polymer structure helps maintain stable charging and discharging performance, while low self-discharge characteristics support longer standby periods.
Yideng manufactures miniature LiPo batteries with controlled production processes and supports application-based customization, including PCM protection integration, wire assembly and connector matching. This allows customers to move from initial product development to commercial production with a battery configuration suitable for their device requirements.
