Description

502540 3.7V 500mAh Lithium Polymer Battery — Rechargeable LiPo Pouch Cell

The FYW 502540 is a compact, rechargeable lithium polymer (LiPo) pouch cell engineered for OEM/ODM projects that demand thin, light and reliable power. With a nominal voltage of 3.7V, a true capacity of 500mAh and an energy rating of 1.85Wh, it delivers stable, consistent output for space-constrained electronic products. The prismatic pouch format (MAX 5.0 × 25.0 × 40.0 mm) allows designers to fit dependable energy storage into slim enclosures where cylindrical cells cannot go.

Manufactured in Shenzhen under strict quality control, every cell is fully tested and shipped with MSDS and KC certification, giving global buyers a compliant, ready-to-import power solution. Whether you are sourcing for wearables, Bluetooth audio, IoT sensors or portable medical gear, this cell offers an excellent balance of energy density, safety and cost.

Key Advantages

  • Thin & lightweight — only ~5 mm thick, ideal for slim, wearable and portable products.
  • True capacity — 500mAh rated / 1.85Wh energy for consistent, long run-time.
  • Flexible customization — capacity, size, PCM/BMS, connector, wire length and labeling can be tailored to your BOM.
  • Safety first — optional protected circuit, short-circuit protection and multi-layer sealing.
  • Certified & compliant — MSDS and KC documentation available; CE / RoHS options on request.
