I just finished my new battery back pack. See i got tired of carrying around a battery extender in a seperate box outside of my pocket. With this new extender, i can easily fit it in my pocket, and then it attaches to my casio so that i dont have to set it on the floor or in my lap. While it makes my casio rather heavy, i think its worth the extra 20 hours i can squeeze out of the batteries without charging. attached are some pictures.<br><br>

<br>Simple view<br><br>

<br>Heres a nice side view to see how big it ends up when on it.<br><br>

<br>This is the tail end of the bacpac and it shows how i cut the button holes and where the cord comes from<br><br>

<br>Heres a good shot to show how big the pack is, its about two casio's high and about an inch longer than the casio, mostly because of the on/off switch attached at the top.<br><br>

<br>One more view for ya

<br><br> Let me know what you think.
