✅ Summary

The ECO-WORTHY 5.12 kWh rack battery is a high-performance lithium iron phosphate (LiFePO₄) unit built for energy storage, backup systems, and off-grid solutions. Designed in a sleek 3U rack format, it’s perfect for modular expansion and easy integration with inverters and smart energy systems.

💡 Independent testing at Wattopjedak revealed a higher-than-expected usable capacity of approx. 4.9 kWh, compared to the 4.6 kWh listed by the manufacturer.

🧪 Independently tested by Wattopjedak – real results, no fluff

We put this battery through multiple full charge/discharge cycles in our own workshop using a Victron-based test setup. Instead of the claimed 100Ah, it delivered around 108Ah – that’s a solid 8% above spec. The measured usable capacity came out to roughly 4.9 kWh, well above the advertised 4.6 kWh. Bottom line: this battery does more than it promises.
