Module-level replacement for shops, rebuilders and distributors: the CATL 4S1P 177Ah NMC module (item CL-4S1P-177) is a 14.8V, 177Ah VDA355 unit rated at 2.6 kWh, and 24 pieces build a 62 kWh pack. For teams quoting a nissan leaf battery replacement job, it is supplied as brand-new stock with no strict MOQ and sample orders for testing, so you can qualify a nissan leaf replacement battery module before committing to volume.
The first question in every quote is volume: how many 2.6 kWh modules a target pack energy needs. Use the grid below to size an order quickly, then confirm the wiring against the vehicle's own pack architecture before anything is ordered.
| Target pack class | Modules needed (≈) | Module energy total | Single-string voltage (verify) | Wiring check before ordering |
|---|---|---|---|---|
| 24 kWh | 9 | 23.4 kWh | ≈133 V | Confirm series/parallel groups against the existing busbar layout |
| 30 kWh | 12 | 31.2 kWh | ≈178 V | Confirm group count and BMS voltage window |
| 40 kWh | 16 | 41.6 kWh | ≈237 V | Confirm module bay spacing and enclosure clearance |
| 62 kWh | 24 | 62.4 kWh | ≈355 V | Confirm full string layout, harness routing and BMS validation |
Three buyers come to this module for three different reasons. Each scenario maps to a specific module fact and a specific first decision.
The job is a partial rebuild, so batch consistency matters more than total volume. Rated cycle life is ≥2500 cycles and internal resistance is ≈0.28 mΩ, and the new-unit check calls for cell voltage gap ≤3 mV.
Decision: order a matched-batch sample set first, confirm the voltage gap, then scale.
Energy arithmetic is simple: 24 modules at 2.6 kWh each. Charging is rated to 1C and discharge to 3C, which sets the practical power ceiling for the finished pack.
Decision: lock the string layout and BMS plan before the 24-piece order is placed.
Fast-moving stock needs transport paperwork, not just cells. UN38.3, CE, FCC, RoHS, IEC62133 and UL are claimed, with MSDS and UN38.3 test reports available.
Decision: choose DDP shipping and confirm documentation before the first pallet.
The numbers a buyer needs to price a job: nominal voltage and capacity, energy per module, current ratings, size, weight and warranty.

The module measures 355 × 150 × 110 mm and weighs 12.5 kg, so the physical envelope and handling are settled early. What decides whether a job succeeds is the sequence a technician follows before the pack is closed up.
Measure the pack bay against 355 × 150 × 110 mm and check lifting gear for a 12.5 kg module.
New units show matte original terminals with uniform factory welding and no re-torque marks.
Verify the busbar plate and crimped sensor wiring match the pack harness before connecting anything.
Establish the module's series position in the string and check polarity before the first connection.
Read the laser engraving and QR code, and match the batch to the factory COA certificate supplied with the carton.
Complete insulation and torque checks and confirm BMS communication before the pack enclosure is sealed.
Used modules circulate in this market, so the buying decision is usually a verification decision. These are the five areas that separate new stock from pulled stock.
New units arrive with the original PVC wrap intact, no residual thermal glue or foam on the bottom, unscratched screws and a clean housing.
Look for matte original terminals, uniform factory welding and stock crimped sensor wires.
New stock carries deep laser engraving, a valid traceable QR code, and cells from the same production batch.
Check for a cell voltage gap of ≤3 mV, tight internal resistance consistency and capacity at ≥99% of rated.
Expect the original CATL carton plus a factory COA certificate matching the batch code on the module.
Temperature ratings decide whether a module suits a regional market. This module is cited for low-temperature performance, and the rating window is wide on both the charge and discharge side.
| Condition | Rating |
|---|---|
| Charge temperature | −20 to 55 °C |
| Discharge temperature | −30 to 55 °C |
| Storage temperature | −20 to 35 °C |
| Max charge current | 1C |
| Max discharge current | 3C |
| Cycle life at rated use | ≥2500 cycles |
