The original 9V AAA battery box (part 88000) was tranformed into a 3S LiPo accu with 650 mAh. It is a difficult work, because you have to fight for each millimeter of space.
The original little electronic of the box also works fine with fully loaded LiPo at about 12,5V. A buck-boost-converter limits (or boosts) the voltage at 11,2V for the SBrick controller.
In the end, this is "poor man's ludicrous mode".
