The CALB L148N58A is a 3.7V 58Ah rechargeable prismatic NMC lithium-ion cell designed for professionally engineered high-power battery systems. It combines a compact aluminum enclosure with strong short-duration discharge capability, low DC resistance and manufacturer-defined module compression requirements. The bare cell requires a compatible BMS, current protection, thermal sensing and mechanically supported module construction.
01 58Ah High-Energy Cell
CALB specifies a minimum capacity of 58.0Ah when the cell is discharged at 1C and 25°C. Based on the user-confirmed 3.7V nominal voltage, this corresponds to approximately 214.6Wh per cell. The large-cell platform supports compact high-voltage modules while reducing the number of individual cell connections required in a battery system.
02 Compact Prismatic Construction
The cell measures 148.24 × 102.80 × 26.66mm without terminals and weighs no more than 946g. Its aluminum housing is protected by blue PET side insulation, an ABS top cover and PET bottom insulation. Clearly marked positive and negative terminals, a safety vent and machine-readable identification support controlled module assembly and traceability.
03 435A Peak Discharge
At a cell temperature of 25°C, the operating-current table specifies a 435A peak discharge limit for 10 seconds and a 100A continuous-current limit entry with a 150-second duration. Current capability changes significantly with temperature, so the BMS must apply the complete temperature-dependent discharge table rather than using the room-temperature value at every operating condition.
04 Defined Voltage Protection
The formal operating-limit table specifies a 4.30V charging limit and a 2.75V discharge limit under normal-temperature conditions. At cell temperatures from -30°C to 0°C, the operating discharge cut-off changes to 2.2V. The BMS must monitor individual cell voltage and temperature and prevent operation beyond the manufacturer’s operating and safety boundaries.
05 Low DC Resistance
At 25°C, ten-second discharge resistance ranges from approximately 1.31mΩ to 1.38mΩ across the specified 20-90% SOC test points. The datasheet also provides temperature- and SOC-dependent resistance data at 25°C, 0°C and -20°C, helping engineers estimate voltage drop, heat generation and available power under changing environmental conditions.
06 Reported 2,000+ Cycle Test
The manufacturer reports more than 2,000 cycles in a 25°C step-charge and 1C-discharge test. Charging follows a multi-stage current and voltage profile up to 4.30V, followed by 1C discharge to 2.75V. Because the document does not state an end-of-test capacity-retention threshold, this result should not be presented as a guaranteed service-life value.
Custom battery pack applications: The CALB L148N58A is suitable for professionally engineered EV, hybrid-vehicle, emergency-start, commercial-mobility, AGV, robotics and other high-power battery systems. MisenBattery supplies matched cells and supports custom module and pack integration, including BMS programming, pack fuses, voltage and temperature sensing, insulation, controlled spacing, module compression, cooling and validated welded interconnects. Welding is permitted only on the approved terminal area outside the rivet, and direct soldering to the cell is prohibited. Supporting CE, UN38.3, RoHS and UL documentation can be provided where applicable to the selected cell, pack configuration and shipment.
