That however also opens up the ability to add them in series, which doubles voltage, and can cause problems if misused, so i understand why it was removed when PF was developed to replace the old 9v 2x2 from the 80's.
  If this could be done, the SBrick would be a powerhouse with the ability to run a ton of XL motors simultaniously for an appreciable duration.
  I'll probably just have to build my own though & be careful not to let the magic smoke out.  less

  This means, basically, that the SBrick can pass a higher voltage and amperage (more watts, theoreticaly almost 4x) through to the motors than the IR sensor could. For all practical purposes, this means a modest improvement if you are using a 6x AA or AAA power unit, which can provide a peak 9v (6x 1.5v); but not through the IR sensor, it limits to 7.4v 1A, probably for battery longevity. But to achieve 10.8 or close to 11.8v, you will need a different or modified power supply (with traditional batteries) or non-traditional batteries.
  For example, you could use 7x alkaline AA to get 10.5v by using a 8-AA pack and a blank (pack linked below) and splicing on a PF cable cut from an extension.
  If you change up your battery chemistry, you could use...    less
