The Li‑ion 3.7 V 4400 mAh battery pack offered by Shenzhen Cyclen Technology Co.,Ltd is a compact power source built around two 18650 cylindrical cells in a 1S2P configuration. It delivers a nominal voltage of 3.7 V and a rated capacity of 4400 mAh, housed in a steel casing. The pack incorporates a lithium nickel manganese cobalt oxide (NMC) cathode, a graphite anode and an integrated protection PCB that guards against over‑charge, over‑discharge and short circuit. A built‑in connector enables straightforward integration into electronic assemblies, and the unit complies with UN38.3 transport safety standards for global shipment.
In the lithium‑ion market the NMC chemistry is favoured for its balance of energy density and thermal stability, while steel casings provide mechanical robustness. Typical energy density for comparable 18650‑based packs ranges from 240 to 260 Wh kg‑1, and the graphite anode contributes to a stable charge‑discharge profile. Standard industry practice includes a Battery Management System that monitors cell voltage and temperature, which the Cyclen pack supplies as a built‑in PCB. The cylindrical form factor aligns with widely used device designs, making the pack a drop‑in replacement for many portable applications.
Potential buyers such as OEMs of handheld tools, LED lighting systems and DIY electronics often request verification of UN38.3 certification and a detailed spec sheet before placing an order. Shenzhen Cyclen Technology does not publish a minimum order quantity, so importers should confirm the MOQ directly with the supplier. Trade terms, packaging options and Incoterms are also subject to negotiation and should be clarified during the quotation stage.

Before placing an order, verify that the supplier can provide a full technical data sheet, UN38.3 certification and any other safety test reports relevant to lithium‑ion batteries. Confirm the exact model number and configuration (1S2P, 4400 mAh) to ensure it matches your device requirements. Request a sample if possible and check the supplier’s harbour trust tier and response record as part of your due‑diligence process.
Discuss logistics early, including the preferred Incoterm (FOB, CIF or others) and the expected lead time for production and shipment. Because the supplier does not publish these details, ask for an estimated timeline and any constraints related to customs clearance in China. Clarify payment terms, such as T/T, LC or other arrangements, and whether a deposit is required before production starts.
Arrange for a third‑party inspection to verify the battery pack’s capacity, voltage and safety features before loading. Request test reports for cycle life, temperature performance and protection circuit operation, and ensure that the inspection agency follows IEC 62133 or equivalent standards. Secure all relevant documentation, including a Certificate of Origin and a Material Safety Data Sheet, to facilitate smooth import clearance.
