Review conclusion	With reservations	Recommended

Only in one review: Voltage 3.2 V (33140 15Ah LiFePO4 cell); Temperature rise 60 °C (BAK 32140FS-48); Weight 270 g (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.

BAK 32140FS-48: The cells delivered nearly their rated capacity and stayed below 60 °C at 40 A; the difference from Gotion is small.
