See zappman's helpful post at http://forums.parallax.com/showthread.php?129738-Get-your-Penguin-working-without-modifing-the-circuit-card.

I got one, it has a nice big lithium battery and a USB smart charger, great for Penguin and other projects. Worth calling your local Shack for. They are on closeout and getting rare, not available online.

Edit: sorry, link corrected

    It's got a 220 mAh 3.7V lithium cell inside, plus:
    Smart charger circuitry to charge safely off of a USB input connection
    Boost circuitry to generate 5V to the USB output connection
    All that plus a white LED flashlight!

    Obviously you can make your own direct battery connections to the 3.7V battery if you like.

    I popped one open to show you boyz the innards; there is double-sided PC board with are lots of little ICs in there doing wonderful things. Check the photos.
