I think the new PF trains could add a lot of functionality to existing 9V (...) (16 years ago, 3-Apr-09, to lugnet.trains, lugnet.technic, lugnet.robotics)

(...) They made it 7.4V because all lithium polymer battery cells are 3.6 - 3.8V. Since this is a pack with 2 cells in series, you get 7.4V. A 3 cell pack is typically 11.2V. As you can see, keeping the old 9V system was not really an option if (...) (16 years ago, 3-Apr-09, to lugnet.trains, lugnet.technic, lugnet.robotics)
