This 46210 cylindrical lithium iron phosphate cell combines a 3.2V nominal voltage with 45Ah nominal capacity, providing approximately 144Wh of nominal energy. Its large cylindrical construction measures 46mm in diameter and 210mm in height, while internal resistance is specified at no more than 1.3mΩ. Complete operating limits must be confirmed before battery-pack integration.
The rechargeable cell provides a nominal voltage of 3.2V and nominal capacity of 45Ah. Its lithium iron phosphate chemistry makes it suitable for professionally engineered rechargeable battery modules. Charge voltage, discharge cut-off voltage and allowable current ratings must be obtained from the complete manufacturer specification before electrical system design.
Nominal energy is approximately 144Wh, transparently calculated from the confirmed 3.2V nominal voltage and 45Ah nominal capacity. This single-cell energy supports the development of higher-capacity battery modules using fewer parallel cells, subject to appropriate voltage configuration, cell matching, structural support and protection-system engineering.
The cell uses a large 46210 cylindrical format with confirmed overall dimensions of 46mm in diameter and 210mm in height. This standardized dimensional description helps engineers plan module layouts, cell holders and mechanical enclosures. Final clearances must account for terminals, insulation, manufacturing tolerances and the approved cell connection method.
Internal resistance is specified at no more than 1.3mΩ. Low cell resistance can help reduce electrical loss and voltage drop when the cell is operated within its approved limits. Finished-pack performance also depends on cell matching, busbar resistance, welded or mechanical connections, fuse selection, cable sizing and contact quality.
The confirmed approximate cell weight is 0.7kg. This value supports preliminary module-weight estimates and enclosure planning, although production-batch variation and additional components must be considered. Pack-level calculations should also include busbars, cell holders, insulation, wiring, the BMS, protective devices, structural supports and the finished enclosure.
This product is a bare rechargeable cell rather than a protected battery or finished energy-storage system. Charge and discharge limits, temperature range, cycle-life conditions, terminal construction and connection requirements are not included in the available data. These parameters must be verified before prototype assembly, validation testing, certification or mass production.
Custom battery pack applications: The 3.2V 45Ah 46210 cell may be evaluated for stationary energy storage, industrial equipment, backup power and custom mobility battery modules after its complete operating specification is confirmed. MisenBattery supplies cells and supports pack integration with a compatible LiFePO4 BMS, fuse protection, approved interconnections, voltage and temperature sensing, electrical insulation, cell spacing, mechanical restraint and thermal design. Availability and scope of CE, UN38.3, RoHS or UL documentation must be confirmed for the applicable product batch, pack configuration and shipment.
