- Weight: Measured with professional equipment, the net weight of the battery is exactly 4244.4g. It exhibits excellent lightweight characteristics. Compared to lead-acid batteries of similar capacity, it is significantly more convenient to transport and install.
- Dimensions: The dimensions are regular 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 indicators for measuring 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 value is approximately 3.295V. The voltage is stable and sits above the nominal voltage range, indicating sufficient initial power delivery capability.
- Internal Resistance (IR): The measured value is an ultra-low 0.22mΩ. This ultra-low internal resistance means less energy loss during charging and discharging, more stable voltage during high-current discharge, and effectively prevents issues like voltage sag and unstable power supply.
3.3 True Capacity Test
For the capacity test, a professional battery capacity tester was utilized, completing charge and discharge cycles according to strict standard procedures. The tester actively recorded the entire process.
The final measured results show that the battery's actual capacity reached 232.51Ah, corresponding to an energy output of 740.91Wh.
The measured data is impressive. The measured capacity not only meets the nominal 230Ah standard but also slightly exceeds it, confirming there is no capacity misrepresentation. In practical use, this surplus provides longer-lasting power support for equipment, fully meeting the high-capacity demands of heavy-duty scenarios like energy storage and motive power.
4. Final Verdict
Overall, this 3.2V 230Ah LiFePO4 battery performed flawlessly throughout this comprehensive hands-on test. Its dimensions and weight are highly regular, its core electrical parameters are excellent, and the actual measured capacity is slightly higher than the nominal value.
Combined with the inherent advantages of the LiFePO4 chemistry—such as high safety and a long cycle life—this cell presents a highly reliable and cost-effective choice for high-capacity power supply applications.
