Only in one review: Current 30 A (33140 15Ah LiFePO4 cell); Resistance 2.25 mΩ (33140 15Ah LiFePO4 cell).

33140 15Ah LiFePO4 cell: Capacity is close to the rating, but its behavior at 40 A puzzled the author, who recommends staying at 0.5–1C.

JGNE 18650 1800mAh: The cell delivered nearly 1800 mAh and performed better at high currents, but loses more capacity in the cold than the 1600 mAh model.
