After a search I haven't found this issue to be reported anywhere else so here goes!
In combination with the FTB mods Gregtech, IC2 and Gravisuit you can produce quite a good explosion without intending to by dropping all the machines on the same power line.
I had a couple tier 2 machines that were using redstone signals to idle at 100%, I dropped the Charge'O mat down next to the Induction furnace and the redstone single for the furnace immediately put the C'O'M into discharge mode which then sucked a bunch of energy out of my Gravisuit.
After that the MFSU exploded taking out the side of my house, chests and such. Several frantic minutes of picking stuff up ensued!
TL;DR
Can we set a toggle on the Charge'O mat to choose Charge or Discharge mode, or someway to limit the machines output visibly? I'm assuming that the Charge'O mat is outputting energy like the other GT machines do but the energy level is too high for the MFSU to absorb and thus *boom*
[edit]
Some testing on SSP indicates that the charge station outputs extreme high voltage, is that an oversight or intended?
