Only in one review: Voltage 3.2 V (33140 15Ah LiFePO4 cell); Capacity at high current 92950 mAh (LiFePO4 EVE Energy 3.2V 90Ah); Energy 288.02 Wh (LiFePO4 EVE Energy 3.2V 90Ah); Temperature rise 45 °C (LiFePO4 EVE Energy 3.2V 90Ah).

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.

LiFePO4 EVE Energy 3.2V 90Ah: The cells exceeded rated capacity, had low impedance, and performed well at up to 90 A; voltage sag was pronounced in the freezer.
