Cornex 314Ah Cells: The Capacity Test Left Me Speechless…

Prepare for the most surprising capacity test I’ve done in a long time. Today we’re taking a deep dive into the Cornex 314Ah LiFePO4 cells from Gobel Power — checking their voltages, inspecting the build quality, and running full capacity tests before assembling their DIY battery kit. I expected solid performance… …but the capacity numbers I got were not what I expected. These cells come rated for an impressive 8,000 life cycles, with a standard charge/discharge rating of 1C/1C, and Gobel Power backs them with a 5-year warranty — so I wanted to put those numbers to the test and see how they perform right out of the box.
