Product Description
KC UN38.3 Lipo Battery Pack, 650mAh 3.7V Lithium Polymer Battery
Advantages of Polymer Batteries
Good Safety Performance

Made with aluminum-plastic flexible packaging instead of metal casing. In case of safety hazards, polymer batteries vent safely while liquid batteries may explode.

Ultra-Thin Design

Can be manufactured as thin as 1mm, making them ideal for slim devices like modern mobile phones and credit card-sized applications.

Lightweight Construction

40% lighter than steel shell batteries and 20% lighter than aluminum shell batteries of equivalent capacity.

High Capacity

10-15% higher capacity than steel shell batteries and 5-10% higher than aluminum shell batteries of the same size.

Low Internal Resistance

Internal resistance as low as 35MΩ, reducing self-consumption and extending device standby time. Ideal for high-drain applications.

Customizable Shapes

Can be economically manufactured in custom sizes and shapes to maximize space utilization in specific device designs.

Simplified Protection Circuit

Inherent safety allows for simpler protection board design, potentially eliminating PTC and fuse components to reduce costs.
