Import 3.2v 160ah Lifepo4 Battery Cell — Buy in wholesale FOB from Supplier in China

The QH-LFP72174138-160AH from Qh Technology is a prismatic lithium iron phosphate cell in an aluminum shell casing, with copper and aluminum terminals for lowvent resistance connections. Nominal voltage is 3.2V and capacity 160Ah, giving a nominal energy content of 512Wh per cell. The dimensions are 72mm by 174mm by 138mm, and the cell weighs 3.46kg. Charge cut-off is 3.65V and discharge cut-off 2.5V, with standard charging at 32A (0.2C) and maximum charge current of 160A (1.0C). The internal resistance of 0.8mΩ is notably low for this capacity class, supporting high-efficiency operation in large-format storage systems.

The aluminum shell provides mechanical rigidity and aids thermal conduction to external heat sinks or liquid cooling plates. Copper bars with M6 bolts are included, allowing bolted busbar connections that avoid the welding equipment needed for cylindrical cell packs. The cell is rated for 5000 cycles at 0.2C discharge with 80% depth of discharge, a figure that reflects conservative prismatic LiFePO4 design with thick electrodes and low current density. Operating temperature spans 0°C to 45°C for charging and -20°C to 60°C for discharging, with storage at -20°C to 45°C for one month or -20°C to 35°C for six months.

Intended applications include solar energy storage, RV and marine house banks, telecom base station backup, and UPS installations where long cycle life outweighs energy density priorities. The 160Ah capacity suits 48V systems built from 16 series cells, yielding 8.2kWh per string without parallel connections. Wholesale buyers should confirm with Qh Technology whether cells are matched for capacity and internal resistance within a tight tolerance, as series string performance depends on cell-to-cell consistency. The three-year warranty requires clarification of whether it covers capacity retention to 70% or 80% of initial rating, as this threshold varies between manufacturers.

Qh Technology is located at 310, Building A, Zhong Chuang Cloud Valley Science and Technology Park, Panyu District, Guangzhou, 511440, Guangdong Province, China. The company holds a harbor trust tier on the platform, with a 0.00% response rate and no recorded average response hours. This lack of response data means buyers cannot assume active sales support and should initiate contact through multiple channels toGauge responsiveness. The address places Qh in Guangzhou's Panyu technology corridor, a district with growing concentration of battery system integrators but less dense cell manufacturing heritage than Shenzhen or Dongguan.

The profile provides no information on factory ownership, production capacity, R&D staff, or certifications beyond the product-level warranty. The inclusion of copper bars, M6 bolts, and insulation sheets as accessories suggests Qh targets pack builders who assemble their own systems rather than end-users. Buyers should verify whether Qh Technology manufactures prismatic cells in-house or sources them from a cell maker, as this determines whether technical support extends to electrode formulation questions or stops at logistics. The three-year warranty is a standard market offering; its value depends on Qh's financial stability and ability to honour claims across international borders.
