I know there's Battery Monitor, but that app is 15MB and I want to replace all my apps on my phone for lightweight ones. No need to have an app hogging 15mb RAM for a widget that shows
Code:
(Vcurrent-Vmin)/(Vmax-Vmin)
in my status bar.

(I need a voltage based based battery percentage because of my extended battery pack.)
