The item is a high‑capacity heat‑resistant lithium polymer battery pack identified as 18650‑22P3S. It incorporates 18650‑type cells in a 3‑cell series, delivering a nominal voltage of 11.1 V and a nominal capacity of 48 Ah. The pack measures 38.5 mm × 211 mm × 206 mm, has an internal resistance of 220 mΩ and is rated for 500 charge‑discharge cycles. The supplier lists a charge current of 7 A and a CC/CV charging method, and the product meets a range of international safety certifications.

The polymer composite casing provides enhanced heat resistance, allowing operation from - 40 °C up to 80 °C, which suits industrial equipment exposed to harsh climates. Certified to UN 38.3, CE, ROHS, UL, FCC, IEC 62133 and other standards, the pack is positioned for solar‑energy storage, portable power devices and manufacturing equipment requiring stable output under temperature stress. Typical industry practice for similar lithium‑polymer packs includes using anti‑static blister packaging and providing a 12‑month warranty, both reflected in the supplier’s offering.

Buyers such as system integrators, renewable‑energy exporters and OEM manufacturers can source the battery in large volumes, with a reported monthly capacity of ten million pieces. The supplier mentions both blister‑card and bulk‑package options, and lists Shenzhen as the export port. While exact pricing and minimum order quantities are not disclosed, interested importers should contact the company to negotiate trade terms, incoterms and payment methods such as Western Union, PayPal or T/T.

Sourcing High Capacity Heat-Resistant Lithium Battery from Sum Electronics Technology Co., Ltd. - China Import Guide

Prior to ordering, ask the supplier for the official test report that confirms the 48 Ah capacity, 500‑cycle life claim and the internal resistance value. Request copies of the UN 38.3, CE and IEC 62133 certificates to ensure the pack complies with the safety standards required in your destination market. Verify the packaging type - blister card or bulk pallet - and any custom labelling needs before finalising the purchase agreement.

Logistics should be arranged through the Shenzhen port, and you need to agree on incoterms such as FOB or CIF. The supplier lists a sample lead time of 7‑15 days and a quantity‑order lead time of 20‑25 days, followed by a 7‑10 day delivery after order confirmation. Discuss payment options, including Western Union, PayPal or T/T, and confirm any required advance deposits to protect both parties.

Arrange a third‑party inspection or factory audit to check weld quality, cell matching and overall pack integrity. Request batch test certificates, a safety data sheet and a compliance report for the listed certifications. These documents, together with the inspection results, provide assurance that the batteries meet the technical specifications you require for your project.
