RE: Single AA Battery conversion to battery pack
like you said,
one wire from the pack to the board,
the other wire from the pack goes to the light and the other wire from the light either goes to a switch or back to the board to complete the circuit.
to use a 9.6volt battery instead, you would do it the same way it is connected now.
can the board and the light handle 9.6 volts????
that I don't know, maybe it can since 6AAs is 9volts.
