There is a nice blog by him with instructions here: http://clavinsup.blogspot.com/
Though I don't see the 902 download there so the instructions are a bit outdated, but still apply.
Just use the 902.zip from that mediafire link (4th post on second link) and the instructions from that blog.
When it comes to batterystats.bin I was told to google it, which I did.
I came across various instructions about letting the battery run dry, then charge til full, delete batterystats.bin though filemanager, then charge for 2 more hours....other instructions said something different.
Basically I got: Charge til full, delete file, run dry until phone turns off, then use normally.
CM7 gives us the option to delete the batterystats in there. (recovery/advanced/wipe battery stats)
So that's it.
Now I don't know if I did it wrong, all I know is it gave me longer life.
