That is correct: Here is quote from http://www.protoolreviews.com/news/20v-m...er/17024/:
Each battery cell has a nominal voltage of 3.6 volts and a maximum voltage of just over 4 volts.

3.6 volts (nominal) x 5 cells = 18 volts

4 volts (maximum) x 5 cells = 20 volts

That’s it. That’s the entire difference in 18V vs 20V Max batteries. It’s only a matter of whether the company is using nominal voltage or maximum voltage as their rating.
