I am a little bit confused with pictures, is it possible to get a picture which cover full board at once? Quality is great but one piece is always better.

Brian as you mentioned caps can fail under overvoltage and when exposed to currents higher then rated. Rated voltage depends on temperature. Reverse polarity also cause caps failure. Now if you put al this together it can be clear how and when they can fail, especially with poor battery connection.

For tantalum caps reversing polarity is very bad and irreversible ending up with short (90%) or open.

So far looks like tantalums here Ok. By the way what is sparking or where you see sparks?
