This SK rechargeable pouch cell is listed with 3.7 V nominal voltage and 20 Ah nominal capacity in the supplied parameters; its exact model remains to be confirmed. Calculated nominal energy is approximately 74 Wh, with dimensions of 9 × 124 × 209 mm and an approximate weight of 440 g. MisenBattery supplies cells and supports custom pack evaluation with model identification, operating limits and mechanical integration requirements confirmed for the intended project.
The supplied parameters list 3.7 V nominal voltage and 20 Ah nominal capacity for this SK pouch cell. These values support initial cell comparison and preliminary series/parallel configuration studies. Final pack sizing should use confirmed capacity test conditions, operating voltage limits and load requirements once the exact cell model and applicable specification are available.
Multiplying the listed 3.7 V nominal voltage by 20 Ah nominal capacity gives approximately 74 Wh per cell. This calculated figure provides a reference for early pack energy estimates. Actual delivered energy depends on the voltage window, discharge profile, temperature and cell condition, which should be evaluated under the intended operating conditions.
The listed dimensions are 9 mm thick, 124 mm wide and 209 mm long. This dimensional information supports preliminary enclosure layout and cell arrangement studies. Confirm whether the measurements include tabs or sealing edges, and obtain tolerances and swelling allowances before finalizing cell supports, insulation, interconnects or production tooling.
The supplied weight is approximately 440 g per cell. This value helps estimate cell mass when comparing preliminary pack configurations and enclosure concepts. A complete pack mass calculation should also include the BMS, interconnects, insulation, enclosure, cell supports and thermal components, with production-cell weight variation confirmed during sourcing and inspection.
Using 74 Wh calculated nominal energy and an approximate weight of 0.440 kg gives approximately 168 Wh/kg. This is a cell-level estimate derived from the supplied parameters. Pack-level specific energy will depend on additional structural, protection and thermal components, while direct cell comparisons should use equivalent energy definitions and weight measurement conditions.
Internal resistance is listed as approximately 0.66 mΩ, with no supplied AC/DC method, frequency or pulse duration, SOC or temperature conditions. Confirm the measurement basis before using this value for incoming inspection or cell comparison. Discharge-current capability and thermal performance require separate specifications and validation under the intended pack duty cycle.
Custom battery pack applications: MisenBattery supplies SK pouch cells and supports custom pack evaluation for mobility, industrial equipment and energy storage projects, subject to model identification and application validation. Integration should include a compatible BMS, fuse protection, voltage and temperature sensing, validated tab-welding and interconnect processes, insulation, cell spacing, swelling allowance and thermal and mechanical design. Confirm applicable CE, UN38.3, RoHS and UL documentation for the specific cell, pack and shipment; certification status is not established by the supplied parameter table.
