Only in one review: Capacity 1995 mAh (Samsung ICR18650-22P); Test current 40 A (EVE 40135 20Ah LiFePO4); Resistance 20 mΩ (Samsung ICR18650-22P); Temperature rise 77.5 °C (Samsung ICR18650-22P).

EVE 40135 20Ah LiFePO4: Capacity matches the rating, but there is internal movement and one cell delivered less capacity at 2C.

Samsung ICR18650-22P: The cell seems close to genuine, but its condition and storage are concerning, so the author advises against buying such cells.
