120v Ford Think! Need help powering 12volt accessories

Newbie question for the lithium batteries. So in order for me to obtain the 120 volts I would need to determine the voltage of each cell in a module right? So if a cell was rated at a nominal voltage of 2 then I would need a total of 60 cells?

I just added some lights since getting the new dc converter. Much brighter than stock. Got them from amazon. Was inspired by the Ford Think Parts post. Thought about getting the halo with the drl but didn’t want to give up unnecessary battery juice.
