103072 LiPo Battery 3.7V 3000mAh 11.1Wh Rechargeable Lithium Polymer Battery with JST Connector

Product Description — 103072 LiPo Battery 3.7V 3000mAh

---

Overview

The HNF Battery 103072 is a high-capacity rechargeable lithium polymer (LiPo) battery engineered for devices that demand sustained power delivery in a slim, portable form factor. With a nominal voltage of 3.7V, a capacity of 3000mAh, and an energy rating of 11.1Wh, this battery offers twice the runtime of standard compact LiPo cells while maintaining a thin, lightweight pouch-cell construction. The 103072 measures 10mm thick, 30mm wide, and 72mm long, making it a practical choice for mid-sized portable electronics where internal space is limited but battery life is critical.

Supplied with a multi-wire JST connector as standard, the 103072 is ready for direct integration into your PCB design or device assembly. Custom connector types, wire lengths, and protection circuit configurations are available for OEM and ODM customers.

Applications

The 103072 form factor is well suited to a broad range of mid-power portable devices. Its elongated 72mm length combined with a 30mm width allows it to fit into slim device housings that cannot accommodate wider prismatic or cylindrical cells. Typical applications include:

Portable barcode scanners and inventory management handhelds, tablet computers and e-readers, portable medical monitoring devices such as pulse oximeters and ECG recorders, field communication devices and walkie-talkies, industrial handheld controllers and PLC remotes, portable GPS navigation units, digital cameras and camcorders, smart home hubs and portable security devices, emergency backup power modules, and educational electronics and STEM development kits.

The 3000mAh capacity makes the 103072 a strong candidate for any application where the smaller 103048 or 103060 cells fall short of runtime requirements, but where form factor constraints rule out larger prismatic packs.

Consistent Performance Across Operating Conditions

HNF Battery 103072 cells are manufactured using high-purity cathode and anode materials under controlled clean-room conditions. Each cell is subjected to a full formation and aging cycle before capacity grading and shipment. This process ensures that every unit shipped meets or exceeds the rated 3000mAh specification and exhibits low self-discharge, stable open-circuit voltage, and consistent cycle performance.

The battery delivers a flat, stable discharge curve across the majority of its capacity range, maintaining output voltage close to the nominal 3.7V until the final stages of discharge. This characteristic is particularly valuable in microcontroller-driven devices and precision measurement equipment, where voltage sag can cause erratic behavior or premature low-battery shutdowns.

Internal resistance is kept low through careful electrode design and electrolyte formulation, supporting clean power delivery even under moderate pulse loads. The battery is compatible with standard single-cell LiPo charging protocols using CC/CV methodology, with a maximum charge voltage of 4.2V.

Safety and Compliance

Every HNF Battery 103072 unit is built with multiple layers of electrochemical and mechanical protection. The cell structure incorporates a pressure-relief mechanism and separator materials designed to resist thermal runaway propagation. A PCM (protection circuit module) is available as an add-on option, providing electronic overcharge protection, over-discharge cutoff, and short-circuit protection for applications where a dedicated BMS is not already present in the device design.

All cells are tested and certified to UN38.3 standards, the international requirement for the safe transport of lithium batteries by air and sea. An MSDS document is provided upon request to assist with customs documentation, hazardous goods declarations, and regulatory compliance in your target market.
