Import 3.2v 120ah Lifepo4 Battery Cell — Buy in wholesale FOB from Supplier in China

The QH-LFP48174166-120AH from Qh Technology is a prismatic lithium iron phosphate cell rated at 3.2V nominal and 120Ah capacity, with an aluminium shell casing that provides structural rigidity and heat dissipation for demanding energy storage applications. Its internal resistance measures 0.8mΩ, enabling efficient charge acceptance and reduced thermal generation under load. The cell charges to a 3.65V cut-off and discharges down to 2.5V, with standard charging at 24A and maximum continuous discharge of 120A, extendable to 240A peak. Dimensions are 48 mm by 174 mm by 166 mm, and each cell weighs 2.80 kg.

Built on LiFePO4 chemistry, this cell offers intrinsic thermal stability and a flat discharge curve relative to layered-oxide lithium-ion alternatives. The aluminium shell construction, rather than a polymer pouch, suits automated pack assembly and provides consistent compression for cell-to-cell consistency in large series-parallel configurations. Cycle life is rated at 5000 cycles at 80% depth of discharge and 0.2C rate, a standard figure for phosphate-based cells in stationary storage duty cycles. The chemistry's lower nominal voltage per cell means more series cells are required for a given pack voltage, but this is offset by reduced BMS complexity and fire-safety margins.

Typical buyers include solar integrators building 48V residential battery banks, EV conversion workshops, and industrial UPS manufacturers. The included copper bars, M6 bolts, and insulation sheets simplify busbar connection during pack build. Buyers should confirm whether Qh Technology provides cell-matching services or grading data, as 120Ah cells from the same production lot can vary in internal resistance and capacity by several percent. The three-year warranty covers manufacturing defects, but field data on calendar ageing in tropical climates should be requested directly from the supplier.

Qh Technology operates from premises in Zhong Chuang Cloud Valley Science and Technology Park, Panyu District, Guangzhou, Guangdong Province, China. The supplier holds a harbor trust tier on the platform, with a response rate currently showing 0.00 percent and zero recorded average response hours. Buyers should note that this profile presents limited interaction history, so direct outreach and verification of current responsiveness are advisable before committing to orders.

The listing focuses on prismatic LiFePO4 cells for B2B battery pack assembly, with no stated manufacturing certifications, ISO accreditations, or OEM client references in the profile. The supplier advertises model-specific technical data and includes accessory kits with cells, but does not disclose production capacity, cell grading protocols, or whether it is the original cell manufacturer or a trading company. Buyers should request factory audit reports, UN38.3 test summaries, and IEC 62619 compliance documentation directly.
