Limit to the number of lithium cells you can safely stack in series?

[dougjohnson]

I have a 510 volt light and I am trying to find out if there is some limit to the number of lithium coin cells that you can safely stack in series.

For instance, if I stack and shrink wrap 170 CR2032 lithium coin cells to make 510 volts, would this pose any danger other than the danger of getting shocked?

Any information would be greatly appreciated.

Thanks
Doug
