Nojoke 4 Pack 3.2V 280Ah LiFePO4 Lithium Prismatic Battery Cell, Grade A Lithium Iron Phosphate Battery, 5000 Life Cycles & 10-Year LifeSpan, for DIY Solar Power Storage System, Marine, RV

I have had the cells for nearly a week now. They all came in excellent packaging and in perfect condition. They arrived identical in voltage (around 3.28V each), which is ideal for storage and a good sign they were well matched. They also included very nice aluminum bus bars and nuts. I do wish there were a few more bus bars for parallel configuration, but there were plenty for wiring them in series. I slowly top-balanced them before installation and have been running them in a 24V off-grid solar setup. So far they have been extremely stable, with very tight cell balance under both light and heavier household loads. Voltage behavior has been exactly what you’d expect from healthy LiFePO₄ cells. Very happy with the quality and would buy again.

Muy buenas y llegan muy rápido

They seemed to be completely charged and no bloating. I have not used them as of now, but in the process of wiring them in.

Excelente todo , todo perfecto me encantó. Mucha eficiencia en el envío. Y el producto excelente. Ninguna queja.
