High-discharge polymer / LiPo cell supply for pack builders who need 25C-60C class discharge, compact pouch formats, thermal-rise review, and current-focused OEM design.
Key specs
3.7V / 4.2V / 4.45V class / About 1.5Ah-22Ah planning bands / 25C-60C by class / High-rate LiPo / polymer
Large-format LiFePO4 cell supply for buyers who need long cycle life, abuse-test review, safer module layouts, and large-capacity building blocks—not finished ESS packs, not high-energy Wh/kg screening, and not complete high-safety custom PACK engineering.
Key specs
3.2V nominal class / About 45Ah-300Ah+ planning bands / About 1C-5C by class / LiFePO4
High-specific-energy lithium cell options, including hybrid solid-liquid review, for long runtime, lightweight equipment, smart devices, and custom digital battery packs.
Key specs
About 3.55V-3.85V by band / About 20Ah-70Ah planning bands / Runtime optimized; band dependent / Li-ion / hybrid solid-liquid
Oval, pouch, prismatic, and shaped lithium cell supply for compact smart devices, portable medical equipment, high-end digital products, and custom OEM packs.
Key specs
3.7V typical / model dependent / About 240mAh-4500mAh planning bands / About 3A-20A format dependent / Li-ion / polymer
Category notes
270-350Wh/kg high-energy and hybrid solid-liquid cell review for long runtime and lightweight packs. Higher density classes need project confirmation.
25C-60C polymer cells for high-current packs, UAV platforms, pulse-power devices, and model aircraft.
Oval, pouch, prismatic, and shaped small-format cells for smart devices, medical equipment, and compact OEM packs.
Large-format LFP cell options for long cycle life, high safety qualifications, and stable module layouts.
Pouch cell selection
Pouch cell selection is not only about capacity. Device envelope, cell thickness, tab direction, protection PCB position, continuous current, peak current, thermal rise, swelling allowance, and compression method decide the final model and pack structure together.
For UAV, tools, pulse-power, and lightweight high-current packs, with 25C-60C discharge, thermal rise, and connector path review.
For long-runtime, lightweight equipment, and premium digital packs, comparing Wh/kg, lifecycle, discharge, and safety files.
For smart devices, medical equipment, wearables, and compact OEM products, focused on thickness, tabs, protection PCB, and certification market.
For thin, shaped, medical, and smart hardware devices that need protection PCB, harness, and connector review.

This section keeps the category's key product capabilities so buyers can judge voltage, capacity, discharge, structure, BMS, and certification range first.
Sourcing language
Pouch, polymer, and LiPo are often used interchangeably. RFQs should also state thickness, tab direction, capacity, continuous current, peak current, swelling allowance, and certification target.
For thin, shaped, medical, or smart-hardware pack projects at cell level.
Use these terms to separate high discharge, high energy, and compact envelope needs.
Buying guide & FAQ
Cell-level sourcing fits buyers with their own pack design, tab connection, protection PCB, compression, safety validation, and traceability capability. If thickness, tab direction, swelling space, BMS, and connector integration are not controlled internally, a pouch or polymer PACK route is usually more efficient.
18650 / 21700 / 32700 formats belong on the cylindrical cell catalog. LFP large-format building blocks stay on the LFP large-cell SKU here, while finished 48V / 51.2V ESS products belong on the ESS catalog. Finished 6S / 12S / 14S UAV packs belong on the drone battery pack category.
High-energy pouch cells prioritize runtime, weight, and Wh/kg. High-rate polymer cells prioritize current, thermal rise, pulse capability, and compression behavior. A real shortlist should compare discharge profile, temperature, swelling allowance, cycle target, enclosure pressure, and safety files together.
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.
