HYS 501535 3.7V 230mAh 0.851Wh Lithium Polymer Battery 5.0x15x35mm Pouch LiPo Cell for Music Equipment Headset
Product Overview
The HYS 501535 is a high-performance rechargeable lithium polymer (LiPo) pouch cell engineered for today's compact portable electronics. Laser-marked with its full electrical identity - 3.7V nominal voltage, 230mAh rated capacity and 0.851Wh rated energy - this cell delivers a dependable, space-saving power source for OEM and ODM projects that demand consistent quality.
With an ultra-slim 5.0 x 15 x 35 mm form factor, the 501535 slips easily into tight device cavities where cylindrical cells simply cannot fit. The soft-pouch construction reduces weight by up to 40% compared with hard-case cells, giving product designers maximum freedom to create thinner, lighter and more ergonomic devices.
Key Features
- True rated performance: 3.7V / 230mAh / 0.851Wh as laser-marked on every cell, no inflated capacity claims.
- Ultra-slim 5.0 x 15 x 35 mm pouch format: ideal for space-constrained PCB and enclosure layouts.
- Stable 3.7V discharge platform: smooth power delivery for sensitive audio circuitry with minimal voltage sag.
- Low self-discharge: retains charge during storage, ready for long product shelf life.
- No memory effect: can be topped up at any state of charge without capacity loss.
- Optional PCM: protection circuit module available with overcharge, over-discharge and short-circuit protection.
- Customizable: connector, wire gauge, PCM and adhesive backing can be tailored to your assembly line.

OEM / ODM Customization
As a flexible pouch cell, the HYS 501535 supports full customization to match your product: custom connector and wire length, added PCM, protective packaging, custom capacity within the same footprint, and private-label printing. Our engineering team works with you from prototyping to mass production.
Quality & Compliance
Every cell is 100% tested for capacity, voltage and internal resistance before shipment. Our manufacturing process follows ISO 9001 quality management, and cells are certified to CE and RoHS standards with UN38.3 and MSDS documentation available for safe air and sea freight.
Packaging & Delivery
Cells are packed in anti-static bags with foam inserts to prevent short circuit and mechanical damage during transit, then shipped in export-grade cartons. Standard lead time is 7-15 working days after deposit, with a monthly supply capacity of 200,000 pieces to support high-volume production.
