从China供应商批发进口503048 3.7v 700mah Lithium Polymer Battery — FOB条款

The VP503048 from Shenzhen Vcell Power Co., Ltd. is a lithium polymer cell rated at 3.7V nominal with a 700mAh capacity and 2.59Wh rated energy. Its dimensional code, 503048, indicates a cell of approximately 5.0mm thickness, 30mm width, and 48mm length, a standard form factor in the prismatic LiPo category. The cell charges to 4.2V cut-off and discharges to 3.0V with PCM protection engaged, with standard charge current set at 0.2C and max continuous discharge at 1.0C.

Constructed with lithium polymer chemistry in a flexible aluminium-laminate pouch, this cell offers higher energy density than cylindrical alternatives of comparable volume. The PCM (Protection Circuit Module) guards against over-charge, over-discharge, and over-current conditions. Typical industry practice for cells of this size includes operation within discharge temperatures of -20°C to 60°C, though sustained high-temperature discharge accelerates calendar ageing. Storage at 25°C with 40-60% state of charge is standard for minimising capacity fade during transit and warehousing.

This 700mAh cell suits IoT sensors, wearable fitness trackers, Bluetooth accessories, and compact GPS modules where space constraints dominate design. Buyers in consumer electronics assembly and portable device OEM procurement source this format for its balance of energy density and footprint. For bulk orders, confirm with Shenzhen Vcell Power whether the PCM threshold and lead wire configuration are fixed or configurable, as these affect integration with existing PCB layouts.

Shenzhen Vcell Power Co., Ltd. is based in Shenzhen, China, a city that hosts one of the world's densest concentrations of battery cell manufacturers and pack assembly houses. The supplier's profile indicates a harbor trust tier, which represents a baseline verification level on the platform. No response rate or average response time data is available, so direct communication to confirm technical support capability is advisable before placing trial orders.

The listing provides electrochemical specifications and dimensional coding but does not state factory certifications (such as ISO 9001 or IEC 62133 test reports), production capacity, or whether the PCM is designed in-house or outsourced. The company's address confirms Shenzhen location, though the exact manufacturing site versus trading office status is not clarified. Buyers should request factory audit reports or third-party test documentation covering UN38.3 transport testing and IEC 62133 safety compliance, as these are standard requirements for lithium polymer cells in international trade.
