Battery pack for digihelix, this goes on the back on a large screen. It starts off with three bars, one blinking, then after one hour it goes down a bar, and after another hour it goes down to one blinking bar. If you tap it the bars will fill up completely and glow before returning to whatever charge it was at. It will also start at blue at full charge, go to purple at medium charge, and red at low charge. It also makes a little sound when you tap it
If I'm out and about or something I thought it would be cute that it slowly lost battery. Also I made it so when you tap it it seemingly gains charge for a second, like in some movies where they tap a meter and it goes up or something. When the charger bar has hit 0, it will flash a "LOW POWER" screen.
