Product overview
Built around an application brief, not an assumed catalog fit.
This 11.1V 3S2P 7200mAh 18650 lithium battery pack is a representative starting point for OEM projects that require a compact rechargeable power source. The three-series, two-parallel configuration establishes an 11.1V nominal voltage and 79.92Wh nominal energy using six cylindrical 18650 cells. A final battery pack is not defined by voltage and capacity alone: the application load, peak-current demand, charging arrangement, physical envelope, cable routing and documentation requirements all influence the approved configuration. PLUSENERG uses the product brief to align cell selection, protection strategy, connector and mechanical integration. This approach helps equipment teams move from an initial target specification to a pack that can be reviewed for prototype and production use without treating a generic catalog image as a finished engineering solution.

Engineering design considerations
Integration details affect the final battery pack.
Mechanical integration
Cell arrangement, cable exit, connector clearance and installation space are considered as one enclosure decision, not as separate afterthoughts.
Protection strategy
BMS functions and thresholds are selected against the application, selected cells, charger and expected operating environment.
Custom battery solution
Turn the electrical and mechanical brief into a battery pack.
PLUSENERG reviews the operating profile, installation envelope and product interface before a final configuration is issued. This keeps the pack aligned with the equipment rather than forcing the equipment around a generic battery.

Application fit
Discuss the operating context before selecting the final pack.
Portable equipment
Application suitability is reviewed against load, charging, installation space, thermal conditions and target-market requirements.
Robotics and mobile devices
Application suitability is reviewed against load, charging, installation space, thermal conditions and target-market requirements.
Industrial instruments
Application suitability is reviewed against load, charging, installation space, thermal conditions and target-market requirements.
OEM equipment integration
Application suitability is reviewed against load, charging, installation space, thermal conditions and target-market requirements.
Quality & documentation review
Documentation is validated against the finished configuration.
Requirements such as CE, RoHS, UN38.3, MSDS or other records are assessed for the final pack, relevant scope, transport route and destination market. A document related to another configuration is not presented as blanket approval.

Technical buyer FAQ
Answers before a project discussion.
What does a 3S2P 18650 battery pack mean?
A 3S2P configuration uses three cell groups connected in series and two cells in parallel in each group. With standard lithium-ion cells, the arrangement has a nominal voltage of 11.1V. The parallel connections increase capacity and current capability, but the final behaviour still depends on the selected cells, BMS, connector and equipment load profile.
What is the charging voltage for an 11.1V 18650 battery pack?
A three-series lithium-ion battery pack normally uses a 12.6V charging voltage. The actual charger interface, charge current, BMS limits and connector must be confirmed against the finished configuration. A 12.6V nominal charger specification does not replace a project review of the charging system.
Can PLUSENERG customize an 11.1V battery pack?
Yes. PLUSENERG can review voltage, capacity, cell arrangement, physical dimensions, connector, BMS and label requirements as one battery-pack brief. The most useful RFQ includes the application, current demand, available installation space, charging method, quantity, target market and any existing battery photos or drawings.
Which applications may use a 3S2P 18650 battery pack?
An 11.1V 3S2P pack may be considered for portable equipment, service robots, industrial instruments and other OEM products. Suitability must be verified against runtime, peak current, charging arrangement, thermal environment, installation space and target-market documentation requirements.
How are dimensions and weight confirmed?
Dimensions and weight are confirmed only after the final cell selection, BMS, cable routing, connector, housing and installation constraints are agreed. This avoids offering a catalog dimension that cannot be maintained after engineering changes. A drawing or available battery compartment size accelerates this review.
Can the connector and wire length be customized?
Yes. Connector type, pinout, wire gauge and cable length can be specified for a project. The equipment-side mating connector, current demand, mechanical routing and polarity controls should be reviewed first. A photo of the equipment connector or an existing sample helps reduce interface risk.
Are CE, RoHS, UN38.3 or MSDS documents included automatically?
Documentation is not assumed from a generic battery image. Requirements such as CE, RoHS, UN38.3, MSDS or other project records are assessed for the final configuration, relevant product scope, destination market and transport route. The applicable documentation is confirmed during the project review.
How do I request a quote for this battery pack?
Use the Request a Quote form and share the application, desired quantity, installation space, continuous and peak current, connector, charging method, destination country and expected timeline. The team can then identify the technical questions needed to prepare a configuration and quotation discussion.
