The HUAXING 32700-6700mAh is a 3.2V, 6.7Ah-class rechargeable LiFePO4 cylindrical cell for electric mobility, backup power and outdoor or industrial energy storage. Its pressure-resistant nickel-plated steel housing, approximately 21.44Wh calculated cell energy and flexible terminal configurations support practical series-parallel battery-pack design. The manufacturer also specifies controlled resistance, rate-capacity and low-temperature performance tests.
With a 3.2V nominal voltage and approximately 21.44Wh calculated energy, this 32700 cell provides a higher-capacity format for compact battery assemblies. LiFePO4 chemistry offers stable output characteristics for mobility, backup-power and energy-storage designs when paired with appropriate pack-level controls.
The manufacturer specifies up to 20.1A continuous charge or discharge for an individual cell. A separate 67A discharge value is defined for a three-second pulse. For assembled packs, the recommended continuous current is no more than 1C, with the final limit determined by the BMS, interconnects and thermal design.
Standard charging uses 1C constant current to 3.65V, followed by constant-voltage charging until current falls below 0.05C. Standard discharge is 1C to 2.0V. Temperature-based charge limits are specified from 0°C to 60°C, with the most permissive 1C charging band at 15-45°C.
The specification defines 2,000 cycles at 1C and 100% DOD with at least 80% capacity retention. A separate 3C test records 700 cycles under the stated 28 ± 2°C procedure. These values are cell-level test results and should be used together with the intended pack depth of discharge and thermal strategy.
AC impedance is specified at ≤8mΩ at 1kHz, while DC impedance is ≤16mΩ at 50% SOC under the defined 1C/10-second method. The datasheet also records at least 99% of initial capacity during a 3C discharge and at least 95% during a separate 6C rate-capacity test.
The bare cell is approximately Ø32.2 × 70.5mm and weighs 145 ± 5g. Manufacturer drawings show flat-top, dual-screw and screw/stud terminal versions, giving pack designers options for busbar layout, service access and mechanical retention in AGV, forklift, mobility and stationary-storage systems.
Custom battery pack applications: MisenBattery supplies HUAXING cells and supports custom packs for electric two-wheelers, three-wheelers, low-speed vehicles, AGVs, electric cleaning equipment, forklifts, communication backup power and outdoor or industrial energy storage. Pack designs should include a LiFePO4-compatible BMS, correctly rated fuse, welded or engineered interconnects, voltage and temperature sensing, insulation, spacing and thermal-mechanical protection. Confirm the ordered capacity grade, terminal style and batch dimensions before production. Supporting CE, UN38.3, RoHS and UL documentation can be provided where applicable to the selected product and shipment.
