从China供应商批发进口105085 5000mah 3.7v — FOB条款

This 5000mAh 3.7V lithium polymer cell from Shenzhen Xinwen Electronic Limited is a rechargeable power source for medium-drain consumer electronics. It has a nominal voltage of 3.7V, a discharge cut-off at 3.0V, and a standard charging voltage of 4.2V. The cell's internal impedance is rated at ≤100mΩ when measured at AC 1KHz after 50% charge, using batteries within one week of shipment.

The battery uses a lithium-ion/lithium polymer chemistry. Standard charging uses a constant current of 0.2C5A to 4.2V, followed by constant voltage until the current drops to 0.01C5A, taking approximately 6 hours. Fast charging at 0.5C5A reduces this to about 2.5 hours. The cell operates in a charge temperature range of 0 to 45°C and a discharge range of -20 to 60°C, with storage recommendations of -20 to 25°C for periods under one year.

Manufacturers and importers of power banks, portable speakers, and handheld devices source this cell for assembly. The supplier provides it in bulk for container quantities, with trade terms typically quoted per unit. Buyers should confirm the exact MOQ, packaging format, and shipping terms (FOB/CIF) directly with Shenzhen Xinwen Electronic Limited before ordering.

Shenzhen Xinwen Electronic Limited is based in Hantong Industrial Park, Shenzhen, Guangdong, China. The supplier is listed with a 'harbor' trust tier on the marketplace. The listing does not provide details on the company's founding year, production capacity, or specific quality certifications.

The product page presents this as a standard-grade lithium battery cell for bulk import. It does not state the supplier's response rate or average response time, which remain at zero on the platform profile. Buyers are advised to verify the supplier's current export licenses and any relevant battery safety certifications (like UN38.3) directly before placing large orders.
