Compact 7.4V LiPo Power for Rechargeable Desk Lamps

A 2000mAh 2S1P battery pack built with 103450-2000 LiPo pouch cells, delivering 14.8Wh in a 54 × 35 × 21mm PVC-sleeved format with integrated protection and 10kΩ NTC support.

🔬 Flat-Pack LiPo Architecture Built Around Real Lamp Integration

When a rechargeable desk lamp has a limited base or rear enclosure, the battery often becomes the component that determines how much space is left for the LED driver, wiring and mechanical structure. This pack uses two 103450-2000 LiPo pouch cells in a 2S1P configuration, providing 7.4V / 2000mAh / 14.8Wh nominal output in a stacked flat structure. The finished pack is approximately 54 × 35 × 21mm and 65–75g, with PVC heat-shrink encapsulation rather than a fixed hard housing. A JST-PH 2.0 / 2P power connector is standard, while cable length, routing, connector type and optional 10kΩ NTC can be adapted to the host PCB. Digital communication is not used in the standard configuration.

⚡ A 7.4V Power Path Designed for Practical Lighting Systems

For lamp designers, voltage is not only a battery specification—it affects the current flowing through the cable, connector and PCB power path. A 7.4V architecture can deliver the same lamp power with lower battery-side current than a 3.7V design, helping simplify current management in compact lighting assemblies. From the battery side, every finished pack is checked for appearance, polarity, voltage, dimensions, connector condition, protection and NTC function; additional electrical and safety validation can cover capacity, DCIR, charge/discharge performance, overcharge, over-discharge, over-current, short circuit, temperature response, vibration and temperature cycling as required by the project. Battery safety design is aligned with applicable IEC 62133-2:2017+AMD1:2021 requirements, while the finished luminaire can be evaluated against applicable IEC 60598-1:2024 and IEC 60598-2-4:2017 requirements. UN38.3 transportation testing applies where required, with CE, RoHS and UL requirements addressed according to the target market, battery design and final product configuration.

Frequently Asked Questions

Choosing a rechargeable desk lamp battery is rarely just about capacity. The host voltage, charging architecture, enclosure space, connector, temperature monitoring and protection settings all need to work together. The following questions address the practical points OEM buyers most often need to confirm before integration.

What are the voltage, capacity and energy ratings of this desk lamp battery?

The pack is rated at 7.4V / 2000mAh / 14.8Wh. It uses two 103450-2000 LiPo pouch cells in a 2S1P configuration. The cells are connected in series, so the pack voltage increases while the 2000mAh capacity remains unchanged.

Can this 7.4V battery pack replace a 3.7V battery in a rechargeable desk lamp?

Not as a direct replacement unless the host electronics are designed for a 2S LiPo system. The charging circuit, LED driver, protection thresholds and PCB power path must support a nominal 7.4V pack and an 8.4V full-charge voltage. A suitable 2S LiPo CC/CV charging system should be used.

What is the finished size and weight of the battery pack?

The finished pack is approximately 54 × 35 × 21mm and weighs approximately 65–75g. The actual value may vary slightly with the final connector, cable length and production BOM, so enclosure fit should be confirmed with the final battery drawing or sample.

Can the connector, cable and temperature sensing be customized?

Yes. The standard power interface is JST-PH 2.0 / 2P, while connector type, cable length, wire specification and cable exit direction can be customized. When the host charging system requires temperature feedback, a 10kΩ NTC can be integrated, including a 3-wire interface configuration where required.

What testing and compliance information is available for this battery pack?

Routine production inspection can cover appearance, polarity, OCV, dimensions, connector condition, protection and NTC function, with project-specific electrical and safety validation available for capacity, DCIR, charge/discharge, short circuit, over-current and thermal response. Battery safety can be addressed against applicable IEC 62133-2 requirements, while finished portable luminaires may require evaluation under applicable IEC 60598 requirements. UN38.3 transportation testing is applicable where required, with CE, RoHS and UL requirements handled according to the target market and final product configuration.
