Freeplay Zero will only power up though the Pi

[jeepjunkie]

I just built my first Freeplay zero over the weekend.  Everything worked great, had a little issue getting ROMS loaded, but I eventually figure out a solution.  Played a few games, had a blast.  I then plugged it into a micro USB charger over night to charge the li-po batteries.  The blue LED light came on and everything seemed hunky dory. The next morning - no LED, no power, nothing.  Now it won't power up unless I plug the micro USB power supply into the Pi itself. It won't power up using the batteries, or plugging in the power supply to the freeplay micro USB port.  HELP!
