I recently installed the EVE 314Ah LiFePO4 battery, and I’m very impressed. The capacity is exactly as advertised, the voltage is stable, and the performance under load is excellent. High-quality cells with reliable construction—highly recommended for any home energy storage or off-grid setup!
The package arrived even though I did not receive shipping information, so I couldn’t track it. Nevertheless, the product works perfectly and the initial tests are very promising. Highly recommended!
The batteries arrived within 7 days, production dates from August 2025, original codes, voltages are all equal at 3.291V, and they have balanced perfectly during operation. Highly recommended!
Very good
