For best effects you should do this on a table which can be raised to
the ceiling, during a lightening storm :-)
Seriously, the goal is simply to provide 4.5VDC from some other source
to allow the Freerunner to boot. A regulated adjustable power supply is
an ideal source.
The tricky part is connecting the power supply to pins in the Freerunner
which would contact the battery. You'll want a steady hand and you
should be very clear on what you are doing.
I will write up the steps with pictures.
