The Misenpower IFR32700 is a 3.2V 6500mAh rechargeable LiFePO4 cylindrical cell developed for professional battery-pack integration. It combines approximately 20.8Wh of nominal energy with up to 3C charge and discharge capability, low AC impedance and specified discharge operation from -20°C to 60°C. Its defined rate, temperature and cycle-life performance supports scalable industrial, mobility and energy-storage battery solutions.
The IFR32700 cell provides 3.2V nominal voltage and 6500mAh capacity when tested at 27°C with a 1C discharge to 2.0V. Its lithium iron phosphate chemistry provides the stable operating-voltage platform required by many industrial battery systems while giving pack designers clearly defined charge and discharge limits.
Each cell stores approximately 20.8Wh based on its nominal 3.2V voltage and 6.5Ah capacity. The cylindrical 32700 format enables scalable series-parallel configurations for projects requiring higher voltage, capacity or total energy, subject to suitable cell matching, spacing, insulation, current distribution and mechanical support.
The specification supports maximum 3C charge and discharge, equivalent to 19.5A based on the 6.5Ah nominal capacity. During its defined 3C discharge test at 25-27°C, the cell delivers at least 97% of nominal capacity. Final pack-current ratings must also account for temperature, cell matching, busbars, wiring, connectors and BMS limitations.
Standard charging uses a 1C constant current to 3.65V, followed by constant-voltage charging until the current falls to 0.01C. The specified procedure is conducted at 25 ±2°C with a maximum total charging time of three hours, providing a defined basis for compatible charger selection and BMS configuration.
AC impedance is specified at no more than 8mΩ when measured at 1kHz. The recommended discharge-temperature range is -20°C to 60°C. Under the datasheet’s defined 1C temperature test, capacity reaches at least 50% at -20°C, 70% at 0°C and 98% at 60°C relative to the 25°C result.
The cell is specified to retain at least 80% of initial capacity after 2000 cycles at 25 ±2°C. This test uses 1C charging to 3.65V and 1C discharging to 2.0V with a 30-minute interval. Actual service life varies with temperature, current, depth of discharge, charging strategy and pack balancing.
Custom battery pack applications: The Misenpower IFR32700 cell may be considered for energy-storage systems, backup power, industrial equipment, mobility platforms and other professionally engineered battery packs. Misenpower supplies cylindrical cells and supports custom pack integration, including cell matching, compatible BMS selection, fusing, welded interconnects, voltage and temperature sensing, insulation, cell spacing, enclosure design and thermal management. Supporting CE, UN38.3, RoHS and UL documentation can be provided where applicable to the selected product and shipment; availability and scope should be confirmed before ordering.
