I immediately pulled the connector off and the batteries seemed to be ok, but still scared the crap out of me! I then had to re-solder a new deans on the second battery that flashed since it melted the connector.

WHAT DID I DO WRONG?? This shouldn't be that difficult. Should I be charging in parallel?

Thanks for your help.
