Only in one review: Test current 40 A (33140 15Ah LiFePO4 cell); Energy 21.18 Wh (VapCell IFR32700 G65); Temperature rise 72 °C (VapCell IFR32700 G65); Weight 270 g (33140 15Ah LiFePO4 cell); Price 13.18 $ (VapCell IFR32700 G65).

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.

VapCell IFR32700 G65: Capacity exceeded the rating, and the cells handled 30 A charging and discharging without problems.
