从China供应商批发进口3.2v 140ah Lifepo4 Battery Cell — FOB条款

The Qh Technology 3.2V 140Ah LiFePO4 battery cell is a prismatic lithium iron phosphate cell in an aluminum shell, engineered for high-cycle applications where thermal stability and safety matter. Its nominal voltage sits at 3.2V with a 140Ah rated capacity, and the cell carries an internal resistance of 0.8mΩ or lower. Cut-off voltages are set at 3.65V for charging and 2.5V for discharging, with standard charging at 28A and maximum charge current reaching 140A. The cell measures 46mm by 200mm by 168mm and weighs 3.05 kg, making it a compact option for pack assembly.

The aluminum shell casing provides mechanical protection and aids thermal dissipation during high-current operation. LiFePO4 chemistry inherently resists thermal runaway, which is why this chemistry dominates stationary storage and electric mobility sectors. The cell is specified for 5000 cycles at 0.2C with an 80% depth of discharge, a standard benchmark for prismatic LiFePO4 cells in the 130-150Ah class. Copper bars, M6 bolts, and insulation sheets ship as accessories, indicating the cell is intended for series-parallel pack builds rather than standalone use.

Buyers typically integrate these cells into 48V or higher-voltage battery packs for solar energy storage, electric vehicles, golf carts, marine propulsion, and backup power systems. The wide operating temperature range, -20°C to 60°C for discharge and 0°C to 45°C for charging, suits outdoor and uncontrolled environments. Storage guidelines recommend -20°C to 45°C for up to one month, and -20°C to 35°C for up to six months, with transportation kept near 20°C. Confirm pack-level BMS compatibility, welding or bolting method, and whether the supplier provides quarterly production-lot test reports before committing to volume.

Qh Technology operates from Zhong Chuang Cloud Valley Science & Technology Park in Panyu, Guangzhou, Guangdong Province, China. The supplier address is Building A, Room 310, with postal code 511440. The company holds a harbor trust tier on the platform, though its response rate currently shows 0.00% with zero average response hours recorded. This profile contains no stated year of establishment, revenue figure, employee headcount, or named client references.

The listing positions Qh Technology as a source of aluminum-shell prismatic LiFePO4 cells for OEM battery pack assembly and renewable energy projects. No factory audit certificates, ISO credentials, or third-party test lab partnerships are mentioned in the source data. Buyers should verify whether Qh Technology owns production lines or operates as a trading company, and request factory inspection reports and cell-level test data before placing volume orders浪尖orders.
