Custom battery pack design and OEM/ODM
From equipment requirements to a validated, production-ready custom battery system—cell selection, series-parallel architecture, voltage and capacity, continuous and peak current, BMS, enclosure, connector, prototype validation, and production planning.
Confirm application, duty cycle, voltage window, runtime, continuous and peak current, envelope, weight, environment, and target market.
Choose a custom LiFePO4 / LiPo battery pack or 18650 / 21700 / 32700 cylindrical route by duty cycle, then review series-parallel layout, energy, thermal path, and protection architecture.
Confirm protection thresholds, CAN / RS485 / SMBus, charger, enclosure, connector, harness, mounting, and service boundaries.
Build against the approved specification and review electrical, thermal, charge-discharge, communication, mechanical fit, and document requirements.
Confirm revision, BOM, test records, and validation boundaries; after the specification is locked, move into controlled assembly and production delivery.
For robot dog, AMR, service, and industrial robot product routes, reviewed by duty cycle and platform integration.

This section keeps the category's key product capabilities so buyers can judge voltage, capacity, discharge, structure, BMS, and certification range first.
Sourcing language
State OEM / ODM scope, duty cycle, chemistry, series-parallel layout, enclosure, connector, BMS communication, and certification targets so the design brief is clear in one pass.
For OEM & ODM lithium battery pack programs that need cell, structure, BMS, and production documents developed together.
Confirm cell format during design review and capture it as chemistry and mechanical constraints in the RFQ.
These needs are better submitted through the matching service entries.
Buying guide & FAQ
Voltage, capacity, peak current, continuous current, dimensions, connector, BMS communication, application, certification target, and quantity are the core inputs. For the full engineering checklist—validation, files, and quantity planning—open the Custom Battery Pack RFQ Checklist under Resources.
Choose Custom OEM when cell selection, series-parallel architecture, BMS, enclosure, connector, or validation still need engineering. Choose battery pack assembly service when the specification or drawings are ready for controlled production.
Request cells when your team already controls pack layout, welding or tab connection, BMS, enclosure, and validation. Use Custom OEM when you need pack-level design development.
Cells fit buyers with their own pack engineering. Modules fit buyers who need standardized series-parallel building blocks. Full PACK systems fit buyers who need BMS, enclosure, harness, connector, and installation-ready integration.
Finished robot / AGV platforms, finished flight packs, and inverter-matched station modules have dedicated product categories. Custom OEM stays for cross-industry pack design that is still undefined.
Global delivery and project documentation
Staricell plans cell supply, pack engineering, BMS integration, test records, and shipment documents around each shipping country, application duty cycle, certification target, and production schedule.
Cell supply, pack engineering, BMS integration, production testing, and export documents are planned around each buyer's shipping country, application, and volume schedule.
Project files can cover UN38.3, MSDS / SDS, shipment labels, test summaries, and documentation paths for CE, IEC, UL, RoHS / REACH, and other requirements.
Operating temperature, continuous / peak current, enclosure protection, connectors, chargers, communication interfaces, and field-service needs are reviewed before mass production.
Cell batch data, matching records, BMS settings, inspection results, and aging summaries can be aligned before sampling or pilot production.
