The 32700-6.0Ah-LR3 is a 3.2V 6000mAh rechargeable LiFePO4 cylindrical cell for professional battery-pack integration. It combines approximately 19.2Wh of nominal energy with 18A continuous discharge, a defined 36A 10-second pulse rating and fast charging up to 3C. Its low impedance, temperature performance and 2000-cycle specification support mobility, UPS, energy-storage and starting-power applications.
The cell provides a nominal voltage of 3.2V and a nominal capacity of 6.0Ah under a 1C discharge test. Its calculated nominal energy is approximately 19.2Wh, providing a scalable energy building block for series-parallel battery configurations requiring increased voltage, capacity or total stored energy.
The cylindrical cell measures 32.2 ±0.3mm in diameter and 70.5 ±0.3mm in height, with maximum limits of 32.5mm and 70.8mm. The bare-cell weight is 140 ±5g. These specified tolerances help engineers plan cell holders, spacing, insulation, busbars and enclosure clearances.
Maximum continuous discharge is rated at 18A, equivalent to 3C based on the 6Ah capacity. For short peak-power requirements, the cell supports a maximum 36A discharge pulse for ten seconds. Pack output must also remain within the current, temperature and voltage limits of the BMS, conductors, connectors and intercell connections.
Standard charging uses 1C constant current followed by constant-voltage charging at 3.65V, with an approximate charging time of 60 minutes. The specification also supports maximum continuous 3C CC-CV charging in approximately 20 minutes. Charger and BMS settings must follow the 3.65V limit and 0.3A end-of-charge current.
AC impedance is specified at 7.5mΩ at 1kHz, supporting efficient current delivery when cells are correctly matched and connected. The operating range covers charging from 0°C to 60°C and discharging from -20°C to 60°C. The temperature curves show the expected reduction in available capacity at lower temperatures.
The cell is specified for at least 2000 cycles at 1C and 100% depth of discharge, with remaining capacity of at least 80%. The representative cycle chart reports approximately 85.36% capacity retention at the 2000th cycle. Actual pack life depends on temperature, current, balancing, charging strategy and mechanical design.
Custom battery pack applications: The 32700-6.0Ah-LR3 may be considered for low-speed electric vehicles, UPS systems, energy storage and starting-power applications. MisenBattery supplies cylindrical cells and supports custom pack integration, including cell matching, compatible BMS selection, fusing, welded interconnects, voltage and temperature sensing, insulation, 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.
