Category : Wearable Rechargeable Cells

Lithium Polymer batteries (LiPo) offer several advantages. It has a greater energy density in terms of weight than Lithium Ion. In very thin cells (under 5 mm) LiPo also provides higher volumetric energy density. Additionally, there is more flexibility in cell sizes and shape with LiPo and a wider margin of safety, with superior stability in over-voltage and high-temperature conditions.

Major Features:
  • High energy density / High capacity High safety
  • High rate discharge performance
  • Special shape : Arc-shape, Trapezoid-shape, Rectangle-shape, I-shape, Narrow-shape
  • Best use of potential rooms of products and perfect for small portable electronics

  • Bluetooth earphone;
  • Wristband, Smart-watch, Pedometer, Wrist healthy products;
  • Micro, smart and professional electronics;
  • Smart card, Medical equipment, Security products, etc.

Minimum order amount:
  • 1000-5000qty depends on size.
