NEVER EVER connect batteries in parallel!
Because no two batteries have exactly the same voltage.
But they do have a very low internal resistance (well, inititally
at keast. Connect them in parallel and both the internal
resistance and the temperature rise sharply ;-)
The resulting current is delta U/R or a small voltage over a very
low resistance. Which will still yield a huge current!
