Specific energy vs Specific power in batteries
Specific Energy: 100–265 Wh/kg. and. Specific Power: 250 - 340 W/kg. According to the theory, power equals energy divided by time; i.e. 1 W = 1 Wh/t. So can guess that t is the discharge time. Li-ion batteries usually have a discharge rate of 1 C, which means that the battery would be discharged in around one hour.
