Designed for Compact Electronics

The 103048 form factor is one of the most widely used LiPo cell sizes in the industry. Its slim 10mm thickness and compact 30×48mm footprint make it an ideal power source for space-constrained devices where every millimeter matters. Common applications include GPS tracking devices, IoT sensors and modules, Bluetooth wearables, smart home controllers, handheld medical devices, wireless earbuds charging cases, small drones and RC models, portable industrial scanners, and emergency beacon devices.

The flat, pouch-cell construction ensures even weight distribution and allows flexible integration into both horizontal and vertical PCB layouts. The JST connector provides secure, tool-free connections with a positive locking mechanism, reducing the risk of accidental disconnection during operation.

Reliable Performance, Cycle After Cycle

HNF Battery 103048 cells are manufactured using high-purity electrode materials and a rigorous production process to ensure low internal resistance and stable discharge performance across a wide temperature range. The battery maintains consistent output voltage throughout most of its discharge cycle, reducing the risk of voltage sag that can affect sensitive electronics.

Each cell undergoes formation, grading, and capacity matching before shipment, ensuring that every unit meets the rated 1500mAh specification. The battery supports standard CC/CV charging protocols and is compatible with common single-cell LiPo charger ICs widely used in consumer and industrial electronics design.

Safety and Compliance

Safety is a core priority in HNF Battery’s manufacturing process. The 103048 battery is built with a multi-layer protection structure that guards against overcharge, over-discharge, and short-circuit conditions. All cells are tested to UN38.3 standards, making them compliant for international air and sea freight shipment. An MSDS document is available upon request to support customs clearance and regulatory compliance.
