CALB 28AH NCM POUCH CELL

Product Overview

This CALB NCM lithium-ion pouch cell has a nominal voltage of 3.7V and a nominal capacity of 28Ah. The supplied specifications list 84A continuous discharge, equivalent to 3C, and a separate 112A peak discharge figure with duration still to be confirmed.

Its 7.2 × 161 × 227mm format provides a starting point for custom pack layout. Standard charging is listed at 28A, while nominal energy calculates to approximately 103.6Wh. Final suitability depends on the confirmed cell specification, load profile, mechanical support, thermal management and appropriately engineered battery protection.

Technical Specifications

01. Basic Specifications

Brand	CALB
Cell Type	NCM lithium-ion pouch cell
Nominal Voltage	3.7V
Nominal Capacity	28Ah / 28000mAh
Calculated Nominal Energy	Approx. 103.6Wh, calculated from 3.7V × 28Ah; not measured usable energy.

02. Charging and Discharging

Standard Charge Rate	1C
Standard Charge Current	28A; consistent with 28Ah × 1C. This is the listed standard current, not a separately established maximum charge limit.
Continuous Discharge Rate	3C
Continuous Discharge Current	84A Consistent with 28Ah × 3C. Confirm the applicable thermal and operating conditions.
Peak Discharge Rate	4C; peak duration and duty cycle require confirmation.
Peak Discharge Current	112A; consistent with 28Ah × 4C. Not a continuous rating. Peak duration, recovery interval and test conditions require confirmation.

03. Dimensions and Resistance

Cell Dimensions	7.2 × 161 × 227mm
Internal Resistance	Approx. 0.8mΩ. Measurement method, temperature and SOC require confirmation; not identified as an AC or DC value.

04. Cycle Information

Reported Cycle Life

2000 cycles, as supplied.
Capacity-retention threshold, charge/discharge protocol, voltage window and temperature are not specified. This is not a guaranteed cycle result at 84A discharge.

Current conversions use the listed 28Ah capacity. Confirm the exact cell model and applicable manufacturer specification before qualification. Cell-level current figures do not establish the operating current of an assembled battery pack.

Key Features

0184A Continuous Discharge Specification

The listed 3C continuous discharge rate corresponds to 84A on a 28Ah basis. Evaluate sustained-load requirements together with cooling, tab connections and the confirmed cell operating limits.

0228Ah Nominal Capacity

The nominal capacity and 3.7V voltage provide approximately 103.6Wh of calculated nominal energy per cell. Actual usable energy depends on current, temperature, voltage limits and aging.

03Flat 7.2mm Pouch Format

The listed 7.2 × 161 × 227mm dimensions support preliminary module layout. Confirm tolerances, tab geometry and assembly allowances before selecting fixtures or finalizing the enclosure.

Applications and Selection Notes

Evaluate this CALB 28Ah cell against the required energy, continuous load and transient demand. The following are potential engineering directions, subject to specification confirmation and application-level testing.

Potential Applications

Custom mobility battery packs: Assess the cell against controller demand, acceleration loads, runtime targets and available cooling.
Industrial equipment battery development: Consider the flat pouch format where installation space and load requirements align with a validated cell and pack design.

Battery Cell Selection Notes

Separate continuous and peak loads. The 84A continuous figure differs from the 112A peak figure. Confirm peak duration, recovery time, SOC and temperature before evaluating transient performance.
Confirm charging and protection settings. The listed 28A is a standard charge current. Obtain the complete charging profile, voltage limits and temperature guidance before selecting a charger or BMS.
Validate the pouch assembly. Review tab connections, insulation, mechanical support, swelling allowance and heat removal. Verify service life under the actual application duty cycle.

Frequently Asked Questions

Can the cell deliver 112A continuously?

The supplied information lists 112A as peak discharge and 84A as continuous discharge. Peak duration is not specified and must be confirmed before use.

Is 28A the maximum charging current?

It is listed as the standard 1C charging current. No separate maximum charge-current rating is established by the supplied data.

Does the 2000-cycle figure mean 80% capacity retention?

No retention threshold is provided. Confirm the original test protocol, including charge/discharge rates, temperature and end-of-life criterion, before making lifecycle comparisons.
