从China供应商批发进口3.2v 130ah Lifepo4 Battery Cell — FOB条款

Qh Technology's QH-LFP48174166-130AH is a 3.2V nominal, 130Ah prismatic lithium iron phosphate cell housed in an aluminium shell, sharing the same 48 x 174 x 166 mm footprint as its 120Ah counterpart but offering higher gravimetric energy density at 2.85 kg. The cell's internal resistance is specified at 0.8mΩ or less, with charge termination at 3.65V and discharge floor at 2.5V. Standard charging proceeds at 26A, with 130A continuous and 260A peak discharge capability. The identical external dimensions allow pack designers to substitute this higher-capacity variant without altering module mechanics or cooling channels.

The 130Ah rating within the same physical envelope as the 120Ah cell implies improved electrode loading or thinner separator design, though the supplier does not disclose manufacturing process details. Like all LiFePO4 cells, it exhibits a 3.2V plateau and superior thermal runaway threshold relative to NMC or LCO chemistries, with a typical onset above 270°C. The aluminium casing provides compression resistance and interfaces cleanly with thermal interface materials in liquid-cooled pack architectures. Calendar life expectations for this chemistry in moderate climates range from 10 to 15 years at 25°C, though actual performance depends on average state of charge and operating temperature.

Target applications overlap with the 120Ah sibling, solar farm storage, commercial 48V rack systems, forklift retrofits, and telecom backup. The marginal capacity increase reduces parallel string count in large|​high-capacity packs, saving busbar copper and BMS channel costs. Buyers evaluating this against the 120Ah variant should model total cost of ownership including cell count, connection hardware, and labour. The three-year warranty and accessory kit of copper bars, M6 bolts, and insulation sheets are carried over from the lower-capacity model.

Qh Technology is located at 310, Building A, Zhong Chuang Cloud Valley Science and Technology Park, Panyu District, Guangzhou, Guangdong, China. The supplier profile indicates a harbor trust tier, with a response rate displayed as zero percent and no recorded average response time. This signals either a new listing, dormant account, or platform data synchronisation issue that buyers must investigate through direct communication channels before placing orders.

The company markets prismatic LiFePO4 cells in two closely related capacities, suggesting a focus on energy storage OEMs and battery pack integrators rather than end consumers. No factory certifications, quality management systems, or client references appear in the profile. The supplier does not clarify whether it manufactures cells in-house or sources from a third-party cell maker. Buyers should conduct due diligence on production origin, requesting supplier audit questionnaires and evidence of in-process quality controls.
