11.1V 2600mAh Battery Pack

HSS Energy manufactures the China 11.1V 2600mAh Battery Pack for OEM projects that need a defined 11.1V source rather than an off-the-shelf battery selected by appearance alone. Before a sample is built, we review working current, peak current, charger, connector, polarity, cable routing, battery compartment and protection requirements. That review matters because two packs with the same voltage and capacity can still behave differently in the equipment if their interface or load limits do not match.

Key Specifications

1. Compact Format for a Defined Power Budget

With approximately 28.86Wh of nominal energy, the three-cell arrangement gives product teams a clear starting point for runtime and enclosure evaluation. An 18650 battery pack also gives mechanical engineers a known cylindrical cell format, although the finished dimensions still need to be checked against the actual battery compartment.

2. Cell Layout and Pack Geometry

The three cells are connected in series, raising nominal voltage while capacity remains 2600mAh. This 3S1P battery pack structure is easy to identify during engineering review, but wire exit direction, insulation, wrapping and final pack tolerance should still be fixed in the approved sample and drawing.

3. Electrical Matching and Protection

Voltage and capacity alone are not enough to approve a battery for production. HSS Energy reviews the charger, continuous load, startup or peak current, connector polarity and protection requirements before setting the electrical specification. In engineering documents, the confirmed configuration may be identified as an 11.1V 2600mAh Li-ion battery; actual current limits remain project-specific.

4. Application Evaluation, Not Blanket Compatibility

The supplied marketing material shows RC toys and robot-type devices as potential application directions. When evaluating an 11.1V battery pack for robot integration, the engineer should confirm load current, peak demand, charger, connector, polarity, available space and operating environment. These examples indicate possible use cases; they do not prove compatibility with every device shown.

5. OEM Interface and Mechanical Customization

Connector type, polarity, lead length, wrapping, label content and pack dimensions can be adapted after the equipment interface is reviewed. A 3S 18650 battery should be approved by drawing or sample rather than ordered from a photograph, especially when the battery compartment, wire routing or mating connector leaves little installation tolerance.

6. Manufacturing and Repeat-Order Control

Xiamen HSS Energy Technology Co., Ltd was established in 2023, and its core partners have more than ten years of lithium-battery industry experience. HSS Energy operates multiple production bases in China with a combined area of approximately 12,000 square meters. For this OEM pack, repeat orders should follow an approved sample and written specification covering cell requirement, connector, polarity, protection, dimensions, label and required documents.

FAQ

What are the nominal voltage, capacity and energy?

The confirmed values are 11.1V nominal voltage, 2600mAh (2.6Ah) rated capacity and approximately 28.86Wh nominal energy.

Can the connector and wire length be customized?

Yes. Connector type, polarity and cable length can be reviewed against the equipment interface before the sample and production specification are approved.

Can the pack dimensions, wrapping and label be customized?

Yes. These items can be adjusted within the limits of the cell arrangement, electrical design and mechanical requirements confirmed for the project.

How are the protection parameters determined?

They are defined after the normal operating current, peak current, charging method and other electrical requirements are confirmed. A generic threshold should not be assumed from voltage and capacity alone.

What information is needed for a quotation?

Please send the battery compartment dimensions, working and peak current, connector details, polarity, lead length, charger information, target market, required documents and expected quantity.

Request a Project Quotation

For the 11.1V 2600mAh Battery Pack, send HSS Energy the device voltage, load profile, battery-space limits, connector and charger information, target market and expected quantity. We will review the interface and prepare a project-specific OEM specification for sampling and quotation.
