Start With Application Requirements
A reliable lithium battery pack project should begin with device data. Buyers need to confirm working voltage, peak current, continuous current, runtime target, installation space, wire length, plug type, storage life, and operating temperature. Hongli focuses on primary lithium manganese batteries and supports CR123A, CR2, CR14250, CR14505, CR17450, CR17505, CRP2, 2CR5, CRV3, CR9V, 3V button cells, and customized lithium battery packs.
| Project Item | What To Confirm |
|---|---|
| Voltage | Single cell or series design |
| Capacity | Runtime requirement |
| Current Load | Pulse and continuous discharge |
| Structure | Size, housing, wire, connector |
| Environment | Temperature and storage condition |
| Compliance | MSDS, UN38.3, transport documents |
Manufacturer Vs Trader
A trader may provide battery models, but often cannot control cell grading, internal resistance, welding quality, insulation design, pack testing, or batch traceability. A direct manufacturer can manage cell selection, pack design, assembly, inspection, labeling, packaging, and export document preparation.
OEM ODM Process
A professional OEM / ODM battery pack process usually includes application review, cell model selection, electrical design, sample drawing, connector confirmation, sample testing, pilot production, quality inspection, packing confirmation, and mass production. For primary lithium battery packs, charging is not allowed, so the design must match one-time discharge use and long storage demand.
Quality Control Checkpoints
Key inspection points include open circuit voltage, capacity, internal resistance, welding strength, polarity, connector accuracy, insulation, leakage, appearance, label information, carton marks, and batch records. IEC 60086 covers primary battery safety requirements, and UN38.3 testing is commonly required for lithium battery transportation.
Bulk Supply And Export Readiness
Bulk battery pack sourcing should confirm MOQ, lead time, storage condition, shelf life, packing method, carton size, shipment mode, MSDS, UN38.3 test summary, and destination market rules. Hongli can support customized lithium battery pack development, stable production, and export-ready documentation for industrial power applications.
