3.Hands-On Testing & Real-World Results
To ensure the highest data accuracy, this hands-on evaluation utilized high-precision professional electronic scales and measurement tools, providing reliable references for subsequent installation and system compatibility.
3.1 Weight & Dimensions
Physical size is a key consideration when designing battery systems for space-constrained installations.
-
Weight: Measured with professional equipment, the net weight of the battery is precisely 4244.4g. It demonstrates excellent lightweight performance. Compared to lead-acid batteries of similar capacity, it offers significantly greater convenience in transportation and installation.
- Dimensions: The battery's form factor is uniform and compatible with mainstream battery compartment designs.
Width: 173.65mm
Thickness: 53.73mm
Height: 204.31mm
3.2 Voltage & Internal Resistance
Voltage and internal resistance are core metrics for evaluating battery performance, directly impacting power supply stability and overall discharge efficiency. The measured data for this cell is excellent:
- Open Circuit Voltage (OCV): The measured reading is approximately 3.295V. The voltage is stable and slightly above the nominal voltage range, indicating a strong initial power delivery capability.
- Internal Resistance (IR): The measured value is an exceptionally low 0.22mΩ. This ultra-low internal resistance translates to lower energy loss during charge and discharge cycles, more stable voltage under high-current discharge, and effectively helps prevent issues such as voltage sag and unstable power output.
3.3 Actual Capacity Test
For the capacity test, a professional battery capacity tester was used, with charge and discharge cycles completed following strict standard procedures. The tester actively recorded the entire process.
Capacity Test Results:
The final measurements show the battery's actual capacity reached 232.51Ah, corresponding to an energy output of 740.91Wh.
The data is impressive. The measured capacity not only meets the nominal 230Ah specification but slightly exceeds it, confirming no capacity misrepresentation. In practical use, this surplus provides longer-lasting power for equipment, fully meeting the high-capacity demands of heavy-duty applications such as energy storage and motive power.
4.Final Verdict
Overall, this 3.2V 230Ah LiFePO4 battery performed flawlessly throughout this comprehensive hands-on evaluation. Its dimensions and weight are highly consistent, its core electrical parameters are excellent, and the actual measured capacity slightly surpasses the nominal rating.
Coupled with the inherent strengths of the LiFePO4 chemistry—such as high safety and long cycle life—this cell stands as a highly reliable and cost-effective choice for high-capacity power applications.
