Only in one review: Voltage 3.2 V (33140 15Ah LiFePO4 cell); Current 30 A (33140 15Ah LiFePO4 cell); Capacity 26290 mAh (LiitoKala LiFePO4 30 Ah); Temperature rise 42 °C (LiitoKala LiFePO4 30 Ah); Price 17.11 $ (LiitoKala LiFePO4 30 Ah).

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.

LiitoKala LiFePO4 30 Ah: All four cells fall short on capacity; the third sags more under load and self-discharges faster.
