The JEVE 38 Ah NCM lithium-ion pouch cell combines 3.7 V nominal voltage with 140.6 Wh of calculated nominal energy. The supplied parameters list 3C continuous discharge, equivalent to 114 A, and dimensions of 7.2 × 229 × 269 mm. MisenBattery supplies cells and supports custom battery pack evaluation, with selection based on confirmed voltage limits, thermal requirements, mechanical clearances and the intended application duty cycle.
01 38 Ah Nominal Capacity
The supplied parameters list 38 Ah nominal capacity and report measured capacity above 38 Ah. These values serve different purposes: nominal capacity supports product comparison and preliminary pack sizing, while the measured result lacks a supplied test protocol. Purchasing and engineering specifications should confirm capacity measurement conditions and acceptance criteria for the intended cell batch.
02 140.6 Wh Calculated Nominal Energy
Multiplying 3.7 V nominal voltage by 38 Ah nominal capacity gives 140.6 Wh per cell. With the listed weight of 710 g, calculated gravimetric energy density is approximately 198 Wh/kg. These figures support preliminary mass and energy studies, while usable pack energy depends on operating voltage limits, load, temperature and system losses.
03 3C Continuous Discharge Rating
A continuous discharge rate of 3C corresponds to 114 A using the nominal capacity of 38 Ah. This listed rating supports initial load-matching discussions for custom battery packs. Confirm its applicable temperature range, discharge cut-off and thermal requirements before design validation, since these supporting conditions and any pulse-current specification were not supplied.
04 Pouch Dimensions for Enclosure Planning
The supplied dimensions are 7.2 × 229 × 269 mm. Using these values as a rectangular envelope gives approximately 0.4435 L and 317 Wh/L of calculated volumetric energy density. Confirm the axis order, tolerances and whether tabs are included, then allow for insulation, pouch swelling, cell support and suitable interconnect access in the enclosure.
05 Resistance for Cell Comparison
Internal resistance is listed at approximately 0.85 mΩ. Measurement method, state of charge and temperature are not supplied, so comparisons require matching test conditions. Confirm the manufacturer’s resistance test and acceptance limits before using this value for incoming inspection, cell matching or pack thermal calculations under the intended operating load profile.
06 Cycle Life and Temperature References
The supplied table lists more than 2,500 cycles and an operating range of −30 to +60°C. Cycle test currents, voltage window, temperature and capacity-retention threshold are not provided. Separate charge and discharge temperature limits also require confirmation, so these entries should retain their qualifications during product selection and application-specific pack validation.
Custom battery pack applications: MisenBattery supplies JEVE cells and supports custom pack evaluation for mobility, industrial equipment and energy storage projects, subject to 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 suitable 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.
