3 wire battery


hi all,

i'm working on small project in want monitor battery percentage display on android phone on top.
the battery consist of polymer li-ion battery 3 wire (red, black , white).
can me code.

moreover, i'm beginner.

thank you

if lucky white wire onewire interface battery control chip.  you need install onewire library , figure out how talk chip in battery.  the battery control chip keeps track of number of electrons going battery when charging , number of electrons coming out of battery in use.

can unwrap battery enough see markings on chip?  use google find out chip has markings , find datasheet chip.
