Will these capacitors work for a 5v mod or VV mod?

I just made an evercool with the caps from radio shack (one of the tantalums I had planned on using originally was shorted). I used one of each at first, the tantalum actually blew up in my face (no damage to me or circuitry, but scared the heck out of me). It has only been up and running for a couple of days but seems to be going strong.

Hmm that's not good. You said you used one of each? As in 1 ceramic and 1 tantalum? Or 2 tant and one wad bad? Mine are rated to 16v so I dot forsee them shorting unless they are actually faulty.

More then likey your going to be running this off Two 3.7 batts in series. So thats 7.4 volts. Personally i like to over kill so i would get the 16 volt caps

3.7V Li-Ion batts = 4.2V fully charged; So 2 fresh off the charger batts = 8.4V
Still under the 10V max, but I agree overkill is always better....

Yeah i had planned on using two tantalums(they don't carry the corect values at the shack, I had ordered them online), but one was shorted. I went to the shack and got two ceramics but someone had put one with a different value in the bin and I did not notice. I didn't think it would cause a problem using two different types but I was wrong.


After re-reading my original post I can see the confusion, but it made perfect sense to me when typing it.
