The Headway 38120S is a 3.2V 10Ah rechargeable LiFePO4 cylindrical cell with threaded terminals for convenient modular assembly. This standard-power version provides approximately 32Wh nominal energy, supports 30A maximum continuous discharge and has a published 100A short-duration pulse rating. Its screw-terminal construction makes it suitable for serviceable custom modules using properly designed busbars and pack-level protection.
The 38120S provides 3.2V nominal voltage and 10Ah nominal capacity, equivalent to approximately 32Wh per cell. Its lithium iron phosphate chemistry supports rechargeable battery modules requiring a stable cell platform and clearly defined 3.65V charge and 2.0V discharge limits.
Recommended discharge current is 10A or 1C, while maximum continuous discharge is specified at 30A or 3C. A separate 100A, 10C short-duration pulse value is published, but its duration is not defined and must be confirmed before system implementation.
The recommended charge current is 10A or 1C, with a published maximum charge current of 20A or 2C. The charger and BMS must enforce the 3.65V cell-level limit and use an appropriate LiFePO4 charging profile for the selected series configuration.
Initial internal resistance is listed at no more than 5mΩ in published distributor data. Incoming cells should still be checked for voltage, resistance, physical condition and batch consistency, then matched appropriately before series or parallel battery-module assembly.
Published cycle performance is at least 2,000 cycles under 1C charge and 1C discharge conditions. Actual service life depends on operating temperature, depth of discharge, SOC window, current profile, cell matching and the electrical and thermal control strategy used in the finished pack.
The cylindrical body measures approximately Ø38 × 120mm, with an overall height near 135mm including the terminal hardware. Threaded terminals simplify mechanical busbar assembly and module servicing when correct torque, conductive hardware, insulation barriers and vibration-resistant connection methods are used.
Custom battery pack applications: The Headway 38120S can support electric mobility, AGVs, robotics, backup power, solar storage and serviceable modular battery systems after application-specific validation. MisenBattery supplies cells and supports custom pack integration, including BMS selection, fuse protection, insulated busbars, voltage and temperature sensing, cell holders, 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.
