Hey all,

This is regarding my optical guitar tuner idea, where a circuit will be
powered from CR2032 coin cells. The circuit will be drawing (I'm guessing)
around 30-50mA due to 2-4 LEDs pulsing at sound frequencies.

I know that CR2032s are designed for around a 1mA continuous draw, and up t=
o
10mA pulse draw, but people make LED keychains out of these things all the
time and those LEDs draw 20mA or so continuously. I want to power the tuner
with these cells, but I don't want the performance of the batteries to
degrade as much due to the relatively high current draw. Therefore, I'll be
putting these batteries in parallel (about 3 or 4 of them in parallel).

Is this okay? What kinds of issues will there be? Will there be issues of
the batteries charging into each other? Things like that?
