Custom Lithium Polymer Battery Packs Manufacturer
Looking for a battery that fits into tight spaces? Nuranu Battery specializes in manufacturing high-quality Lithium Polymer (LiPo) battery packs known for their lightweight design and flexible form factors. Unlike cylindrical cells, our pouch cells can be customized in thickness (as thin as 2mm) and shape to maximize the internal space of your device.
Lithium Polymer Battery Packs Definition
A lithium polymer (LiPo) battery pack is a rechargeable power source that uses multiple lithium polymer cells with a polymer electrolyte instead of the liquid electrolyte found in traditional lithium-ion batteries. These battery packs are also known by various names including Li-poly, lithium-poly, PLiON, and LIP.
