I also have the 1515 2.5d so I know the bit of paper you're talking about. The * after 80 is telling you to look at the bottom of the table, where there is another * . After the * it says "At max voltage. Otherwise,=Watts/your voltage"
"At max voltage" means 80amps is the 20sec max current draw on max voltage, which is 35v.
"Otherwise,=Watts/your voltage" means the max watts for 20 seconds (2700watts) divided by the voltage your using.
So say your using 5s (18.5v) like me it would be
2700 divided by 18.5 = 146 amps for 20 seconds is the maximum that motor is able to handle on that voltage. It doesn't mean it will always draw that much power though, since it can only use what your batteries can put out. And even if it did hit that current, in a car it would usually only be for the first second or 2 of take off.
