11.1V 5000mAh Battery Pack

HSS Energy manufactures the 11.1V 5000mAh Battery Pack for equipment where runtime has become the main limitation. The move to 21700 cells in 3S1P raises capacity to 5Ah without adding parallel groups, and the 15A continuous rating provides clearer load capability. Final connector, cable, BMS settings and dimensions are confirmed against the actual device before sample approval.

Key Specifications

1. More Runtime from a Three-Cell Pack

One 5000mAh 21700 cell sits in each series position, giving 5Ah capacity and approximately 55.5Wh of nominal energy. For customers comparing an 11.1V 5Ah battery pack, the practical benefit is more onboard energy without adding a parallel cell group. Runtime still depends on load and operating pattern, so final validation belongs in the finished equipment.

2. 15A Output Gives the Load a Clear Boundary

Capacity does not tell you whether a pack can carry the load. This model supports up to 15A continuous discharge with a 15A BMS reference, giving the 11.1V 5Ah lithium battery pack a clearer operating envelope than capacity alone suggests. HSS Energy checks normal current, startup demand and short peaks before protection values are finalized; the reference charge limit is 2.5A.

3. Three 21700 Cells Keep the Architecture Simple

With one 5Ah cell in each series position, the confirmed 3S1P 21700 battery pack avoids a parallel group. That means fewer interconnects and a simpler internal layout than higher-parallel designs. The approved cell model, insulation, BMS settings, polarity and connector are then fixed as controlled items for repeat production.

4. Cable Exit Matters as Much as Pack Size

The pack measures approximately 68 x 22 x 72 mm and weighs about 0.25kg, but the real integration constraint is often what happens at the cable exit. On this 11.1V 21700 battery pack, HSS Energy can match connector type, lead length, wire gauge, polarity, exit direction, wrapping and label requirements. Sample approval should confirm both the finished envelope and the space needed around the interface.

5. Applications Where 5Ah Makes a Difference

The strongest fit is equipment designed around an 11.1V architecture that benefits from longer operating intervals without moving to a much larger battery module. That makes the 11.1V 5000mAh lithium ion battery pack worth evaluating for surveillance and monitoring systems, compact robots or automated devices, and selected portable electronics. Under the same load, 5Ah can extend time between charges versus lower-capacity options. Final suitability still depends on current, charger, available space, connector and environment; the supplied application image remains a marketing reference, not a compatibility list.

6. Repeat Orders Need More Than the Same Label

Once a sample is approved, repeatability depends on more than matching the label. Cell model, BMS settings, polarity, wire length, dimensions, labeling and agreed inspection points are fixed in the production specification. Depending on project requirements and availability, HSS Energy can evaluate cell options from EVE, DMEGC, BAK, LG and Samsung; the approved model then remains a controlled item for repeat orders. Factory and batch photos support manufacturing context, while exact-model claims should only be used when the photographed batch is verified.

Production Evidence

The following supplied photos support manufacturing and batch-handling context. They should not be described as exact-model production evidence unless the photographed batch is internally verified.

FAQ

What are the main electrical ratings?

The battery is rated at 11.1V nominal voltage and 5Ah capacity, providing approximately 55.5Wh nominal energy. The supplied specification lists a maximum continuous discharge current of 15A.

What chemistry and cell format are used?

The confirmed chemistry is NCM, using 21700 cylindrical cells in a 3S1P configuration. The exact cell model is confirmed in the approved production specification according to project requirements and availability.

What is the maximum charging current?

The supplied specification lists 2.5A as the maximum charge current and recommends charging at approximately 0.5C.

What are the charging and discharge cut-off limits?

The supplied specification lists a charge cut-off voltage of no more than 12.6V and a discharge cut-off voltage of at least 7.8V, with 9V recommended for discharge cut-off.

What cycle life is specified?

The technical sheet states more than 800 cycles with remaining capacity above 80% of initial capacity. Because the complete cycle-test conditions were not supplied, this should be treated as a technical-sheet reference rather than an unconditional service-life guarantee.

Can the connector and cable be customized?

Yes. Connector type, wire gauge, cable length, polarity and exit direction can be reviewed according to the equipment interface and current requirements.

Can it be used with any 11.1V device?

No. Voltage alone does not determine compatibility. Continuous and peak current, charger settings, connector, polarity, available space, cut-off behavior and operating environment also need to be checked.

What information is required for a quotation?

Please provide the equipment application, normal and peak current, available battery-space dimensions, connector and polarity requirements, cable length, charger information, target market, required documents and expected quantity.
