Only in one review: Voltage 2.3 V (66160 LTO battery cell); Capacity 27500 mAh (66160 LTO battery cell); Weight 2000 g (LiFePO4 EVE Energy 3.2V 90Ah).

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.

66160 LTO battery cell: After being stored discharged, the cell still works, but its capacity drops sharply as load current rises.
