High-Performance Custom Li-Polymer Battery Packs

Gloflux offers premium, custom-engineered Lithium Polymer (Li-Polymer) battery packs designed to meet the most stringent space, weight, and power requirements of modern electronic devices. Utilizing advanced pouch cell technology, our LiPo battery packs deliver exceptional volumetric energy density, flexible form factors, and ultra-lightweight profiles.

Key Product Features

  • Flexible & Customizable Dimensions: Unlike rigid cylindrical cells, our Li-Polymer packs can be customized in thickness, width, and length to perfectly fit your device’s internal chassis, maximizing every millimeter of available space.

  • High Energy Density: By leveraging state-of-the-art material formulations (including high-voltage 4.35V or 4.4V systems), our packs provide extended device runtime within an incredibly lightweight footprint.

  • Intelligent BMS Integration: Every battery pack is equipped with a custom-designed Battery Management System (BMS) or Protection Circuit Module (PCM). This ensures robust protection against overcharge, over-discharge, over-current, short circuits, and thermal runaway, with optional support for communication protocols like I²C, SMBus, or HDQ.

  • Excellent Cycle Life & Low Self-Discharge: Engineered for longevity, our LiPo packs retain 80% or more of their original capacity after 500+ full charge-discharge cycles, featuring minimal power loss during standby.

  • Certified Safety: Manufactured under strict ISO9001 standards, our battery packs are designed to pass global compliance tests including UL1642, IEC62133, CE, CB, UN38.3, and RoHS.
