Import 3.6v 3300mah Lithium Ion Battery Pack — Buy in wholesale FOB from Supplier in China

This 3.6V 3300mAh lithium ion battery pack from Grace Battery Technology Development Co., Ltd employs NMC cathode chemistry with a graphite anode, delivering a nominal 3.6V and typical capacity of 3450mAh with a rated 3300mAh minimum. The cylindrical cell format with integrated smart battery management system targets IoT device manufacturers, portable medical equipment builders, and industrial backup power system integrators. The 3300mAh capacity positions this unit in the mid-range density segment for 18650 or similar cylindrical formats, with the BMS providing cell-level protection against common fault modes.

The NMC cathode composition (LiNiMnCoO2) paired with graphite intercalation anode follows standard lithium ion architecture, with the cobalt content in NMC improving rate capability compared to LFP alternatives at the cost of thermal runaway sensitivity. The smart BMS referenced in the source description typically monitors cell voltage, temperature, and current, with MOSFET-based switching for fault isolation. Heat dissipation characteristics depend on cell can material (typically nickel-plated steel or aluminum), cell-to-cell spacing in the pack, and whether the BMS includes passive balancing or more advanced active balancing circuitry. Typical DC internal resistance for cells in this capacity class ranges from 20 to 35 milliohms, affecting voltage sag under load and overall efficiency in high-pulse applications.

Target applications include telecommunications infrastructure backup, portable diagnostic equipment, handheld industrial tools, electric mobility subsystems, and remote sensor networks. The OEM integration focus suggests buyers will require dimensional drawings, connector specifications, and communication protocol documentation for BMS interfacing. Trade specifics (MOQ, lead time, unit pricing) are not present in the source data and must be confirmed directly with Grace Battery Technology Development Co., Ltd. The source mentions FOB and CIF shipping options, with packaging tailored for transport safety.

Grace Battery Technology Development Co., Ltd is located at Room 101B, Building 16, No. 481 Guiping Road, Xuhui District, Shanghai 200000, China. The supplier's profile indicates a harbor trust tier, representing entry-level verification within the platform classification. The recorded response rate of 0.00 percent and zero average response hours signal potential communication challenges, and buyers may need to follow up through multiple channels or consider an on-site representative for order placement. No factory audit results, ISO certificate details, or quality management system documentation numbers are visible in the provided source material.

The company markets this 3300mAh pack as an OEM solution for sectors including telecommunications, medical devices, and electric vehicles, with emphasis on smart BMS integration and bulk supply flexibility. ISO and CE certifications are referenced in the source text, though without certificate identifiers, scope of accreditation, or testing laboratory names. The profile does not disclose manufacturing capacity, number of production lines, engineering staff count, or major customer relationships. Years of operation, annual revenue, and export market history are similarly absent from the available data.
