If you don't need it as a mod, there is Battery Circle. It looks just like the one in the picture, but it's on the notifications bar. When you pull the bar down, it gives you battery temperature, voltage and how long since unplugged.
Looks like you need to Deodex for that mod. Brainwash how did you do the deodexing I found the info over at my droid world but not sure how to flash the deodexed file.
Thanks for any help
