Li-Polymer battery are made of soft aluminum-plastics compound packaging .Internal is half solid polymers.Discharge stability, high efficiency, the internal resistance small.safety performance is better, and has overcurrent, overvoltage protection devices. Cycle life is more than 500 times.


Evolving from Lithium-ion batteries, Lithium polymer batteries offer a distinct advantage over their predecessor in terms of cost, utility, durability and flexibility. A Lithium-polymer battery can be shaped to fit in an array of devices. As cell phones become thinner, it is important for battery manufactures to develop new ways to charge these ever important devices.


Using a lithium-polymer battery allows the manufacturer to shape the battery in essentially any way they please. This allows for more freedom in designing the true power behind our mobile devices. Another advantage of lithium polymer cells over nickel-cadmium and nickel metal hydride cells is that the rate of self-discharge is much lower.


Category : Ultra Thin 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.


Pay attention Li-ion Battery

  • The batteries, packs, and chargers you are purchasing are for professional use.
  • You are supposed to have sufficient knowledge in handling the products.
  • You will only charge the batteries and packs in a fire proof container. You will not leave the product on wooden materials or a carpet environment that would help induce the spread of fire.
  • You will not put or use products in places adjacent to flammable materials and you will take caution, and wear protective cloths, glass, and gloves.
  • You will not leave the batteries, packs, and chargers unattended during charging and using.
  • When you want to use Li-ion batteries to make packs a Protective Circuit Board (PCB) is required.
  • Any modifications of battery, packs, and chargers will void the warranty.
  • If you make battery packs using the single Li-ion or Li-polymer cells and PCB from us, we are not responsible for the final battery pack performance and liability as the workmanship and assembly details could lead to defects.
  • Herculesi is NOT responsible for any damages and consequences caused by misuse.
