Don't buy into that marketing BS - That's more than likely the total cell rating as a lot of these batteries are listed nowadays - it does not include power lost from dc-dc conversion
Each cell will be 3.4 or 3.7 volts depending on chemistry
Let's calculate 12v Ah:
3.5 x 60 = 210 wh
210 x 0.85 (assuming 85% efficiency) = 178.5 wh
178.5 / 12 = 14.875 equivilant Ah
There are many solutions avail today that are much cheaper then this battery that offer higher capacities
