overkill solar sells 100Ah Frey cells, rated for 2C continuous discharge. that meets my incredibly arbitrary “Grade A” metric.
cells that heat up when discharged faster than 0.5C being EV grade, ok maybe that’s “EV grade” but i expect a lot from cells.
start with a good cell, it’s still going to degrade. “poor quality cells” just start closer to the finish line..
LiFePO4 cells die much faster with higher temperatures, and self-heating from charge or discharge just speeds up to the finish line faster.
