Import Lithium Polymer Battery — Buy in wholesale FOB from Supplier in China

Sum Electronics Technology Co., Ltd. supplies a compact 16450‑type lithium‑polymer cell that measures 8 mm in diameter and 40 mm in length. The battery delivers a nominal capacity of 180 mAh at a nominal voltage of 3.7 V, with a charge voltage of 4.2 V and a maximum charge current of 1.4 A. Its chemistry is based on a manganese‑dioxide anode, mercury‑free zinc‑powder cathode and a potassium‑hydroxide electrolyte, providing stable performance across a wide temperature range. The product meets a comprehensive list of safety and performance standards including UN38.3, CE, RoHS, UL, FCC, IEC62133, CQC and MSDS, which are typical for high‑reliability LiPo cells used in wearables and IoT sensors.

The cell’s operating temperature spans from - 40 °C to 80 °C, while storage conditions are recommended between - 20 °C and 60 °C, making it suitable for outdoor and harsh‑environment deployments. With a rated cycle life of 500 full charges, the battery maintains capacity under repeated use, a figure that aligns with industry expectations for small‑format LiPo cells. Packaging options include individual blister cards or bulk packs, allowing importers to choose the most efficient format for their distribution model. The supplier reports a monthly output capability of ten million pieces, indicating capacity to fulfil large‑scale orders.

Target applications include wearable health monitors, miniature drones, portable sensors and other compact electronic devices that demand high energy density in a small footprint. Lead times are stated as 7‑15 days for samples and 20‑25 days for quantity orders, with a subsequent delivery window of 7‑10 days after order confirmation. Payment methods listed are Western Union, PayPal and T/T, while typical Incoterms offered are FOB from Shenzhen port. Buyers are encouraged to request detailed certification documentation and to confirm any custom colour‑coding or terminal configurations before finalising the purchase.

Sum Electronics Technology Co., Ltd. is based in Zhutang Cun, Fenggang Town, Dongguan, Guangdong Province, China (postal code 523681). The supplier carries a harbour‑tier verification; however, the listed response rate is 0 % and no average response time is recorded, so prospective buyers should establish a clear communication channel early in negotiations. The company’s profile emphasises direct sourcing from a manufacturer in Dongguan, which supports rapid scaling of production volumes.

The firm can supply up to ten million units per month and offers a range of safety certifications that align with international standards for lithium‑polymer cells. Their product catalogue includes bulk and blister‑card packaging, and they accommodate both sample orders and large‑scale procurement. While the supplier mentions flexible payment options, buyers should confirm the exact terms, any required deposits and the preferred Incoterm for shipment from Shenzhen port.
