Cylindrical lithium cells
Cylindrical lithium cell sourcing for OEM battery pack production, covering 18650, 21700, and 32700 LiFePO4 cells with capacity, discharge rate, internal resistance, batch traceability, series-parallel PACK layout, and BMS integration review.
Cylindrical cell products
18650 cylindrical lithium cell sourcing route for portable devices, medical equipment, smart hardware, security products, and custom OEM battery packs that need mature supply, cell matching, and flexible series-parallel layouts.
Best fit
Cell model dependent / Portable devices / 18650 Li-ion / NMC by project
21700 cylindrical lithium cell sourcing route for OEM battery packs that need higher cell capacity, fewer parallel cells, stronger energy density, and current margin within the available equipment space.
Best fit
Cell model dependent / Robotics / 21700 Li-ion / NMC by project
32700 LiFePO4 cylindrical cell sourcing route for safer long-life OEM battery packs, 12V / 24V modules, backup systems, mobility devices, and industrial equipment that need thermal stability and cycle-life planning.
Best fit
Cell model dependent / 12V / 24V battery modules / 32700 LiFePO4
Selection route
For mature sourcing, smaller-diameter mechanical constraints, portable devices, and cost-controlled OEM packs.
For higher cell capacity, fewer parallel cells, stronger energy density, and a larger current margin.
For long-life and safety-priority modules, including 12V / 24V packs, backup power, and industrial equipment.
Cell to PACK
If the buyer does not have complete cell matching, welding, BMS, enclosure, and certification capability, the cylindrical pack route can start from equipment space, voltage, capacity, continuous current, and connector requirements.
Mature 18650 cylindrical-cell battery pack platform for OEM devices that need stable sourcing, flexible series-parallel design, BMS protection, wiring harnesses, and cost-controlled sampling.
Best fit
Cell model dependent / IoT hardware / 18650 Li-ion / NMC by project
Custom 21700 cylindrical lithium battery pack for OEM equipment that needs higher cell capacity, series-parallel architecture, enclosure, connector, BMS, communication, and validation planning.

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.
