SK Innovation CE0305S001A, identified as series C33 E305, is a rechargeable lithium-ion polymer pouch cell with 3.65 V nominal voltage and 30.5 Ah nominal capacity in the supplied parameters. Calculated nominal energy is approximately 111.33 Wh. The list specifies 91.5 A continuous discharge and 125 A discharge for 30 seconds. MisenBattery supplies cells and supports custom pack evaluation with confirmed electrical, thermal and mechanical requirements.
01 30.5 Ah Capacity and Approx. 111.33 Wh Energy
The supplied nominal ratings are 3.65 V and 30.5 Ah, giving approximately 111.33 Wh of calculated nominal energy per cell. These figures support preliminary pack configuration and energy estimates. Delivered capacity and energy should be evaluated under the intended load profile, voltage window and temperature, with cell condition and protection settings taken into account.
02 91.5 A Continuous Discharge, 125 A for 30 Seconds
Continuous discharge is listed as 91.5 A, equivalent to 3C using the 30.5 Ah capacity basis. A separate peak discharge rating is 125 A for 30 seconds. Keep the sustained and timed limits distinct, and confirm starting SOC, temperature, recovery intervals and cooling requirements before establishing the complete pack's operating duty cycle.
03 Defined Continuous Charge and Regen Limits
The supplied continuous charge and regenerative current is 54.6 A, with a separate peak regen current of 125 A for 30 seconds. Regenerative charging should be coordinated with the BMS, voltage limits and temperature sensing. Confirm the allowed SOC range and thermal conditions, and do not substitute peak regen current for a general charging rating.
04 Standard Charge and Discharge Procedures
Standard charging is listed at 1C to 4.2 V with a 0.05C termination current, while standard discharge uses 1C to a 2.7 V cut-off. On the stated capacity basis, 1C equals 30.5 A. These procedures provide a reference for testing, with the full charging method and protection settings confirmed before pack implementation.
05 7.6 mm Pouch Thickness and 610 g Weight
The supplied dimensions are 7.6 × 210 × 195 mm in thickness, width and height, with a listed weight of 610 g. These values support preliminary enclosure layout and cell-mass calculations. Mechanical integration should confirm tab boundaries, dimensional tolerances and swelling allowance, with appropriate cell support, insulation and a validated pouch-tab connection process.
06 Separate Charge and Discharge Temperature Ranges
The list gives a discharge temperature range of −30 to +55°C and a charge range of −20 to +55°C with an unresolved footnote. The missing charging conditions must be confirmed before low-temperature operation. Current limits should be matched to temperature and SOC rather than applied uniformly across either listed range.
Custom battery pack applications: MisenBattery supplies SK Innovation CE0305S001A 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 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.
