The Tianjin New Energy 58Ah NCM pouch cell combines a 3.7V nominal voltage with approximately 214.6Wh of calculated energy in a slim 11 x 148 x 313mm format. Preliminary data reports up to 4C charging, 4C continuous discharge and 16C instantaneous output. These high-rate values require confirmation of current duration, SOC, voltage, temperature and cooling conditions before pack design or commercial integration.
01 58Ah Capacity and 214.6Wh Energy
The cell is rated at 3.7V and 58Ah, providing approximately 214.6Wh of calculated nominal energy. Customer-supplied capacity-grading information reports an approximately 61Ah result, equivalent to about 225.7Wh at nominal voltage. The 58Ah rating should remain the basis for guaranteed pack-capacity calculations until minimum capacity and official test conditions are confirmed.
02 Slim Large-Format Pouch Design
With reported dimensions of 11 x 148 x 313mm, this large-format pouch cell provides substantial capacity in a thin profile. The format supports space-efficient module layouts for professionally engineered mobility and industrial battery systems. Dimensional tolerance, swelling allowance, tab geometry, compression pressure and cell weight must be confirmed from production samples before enclosure tooling is finalized.
03 Reported 4C Continuous Output
Preliminary information indicates continuous discharge capability of up to 4C, corresponding to a calculated 232A based on 58Ah. This output level can support high-current battery modules when validated under the intended operating conditions. Cell temperature, voltage sag, cooling method, busbar resistance and parallel-cell current sharing must be assessed before selecting the working current limit.
04 Up to 4C Fast-Charge Platform
The supplied information reports charging capability up to 4C, equivalent to a calculated maximum of 232A. The standard charging current, CC/CV transition point, SOC window, temperature range, cooling requirements and cycle-life impact are not specified. Charger and BMS settings should therefore follow a complete manufacturer-approved charging profile rather than the C-rate headline alone.
05 Low Resistance and Instantaneous Output
Internal resistance is reported at approximately 0.4mΩ, supporting low conduction loss and strong current response when properly connected. Instantaneous discharge is listed at up to 16C, or a calculated 928A, but no duration is defined. This figure must not be treated as a continuous rating; duration, SOC, voltage, temperature and recovery requirements need written confirmation.
06 Reported Long Cycle Life
Cycle life is reported at no fewer than 3,000 cycles, indicating potential for repeated-use traction and industrial applications. However, the charge and discharge rate, depth of discharge, temperature and remaining-capacity threshold are not stated. Pack-life projections and warranty commitments should be based on a controlled test report or application-specific validation rather than the cycle count alone.
Custom battery pack applications: After electrical and thermal validation, the cell may support electric two- and three-wheelers, commercial mobility, AGVs, robotics and high-current industrial modules. Misenpower supplies cells and supports custom pack integration with a matched BMS, fuse protection, welded tab interconnects, voltage and temperature sensing, electrical insulation, controlled cell spacing or compression, cooling and mechanical restraint. Supporting CE, UN38.3, RoHS and UL documentation can be provided for the applicable product and shipment; availability, scope and validity must be verified before ordering.
