It is the "BP" power rail commonly found in Freescale documentation, that is not actually connected directly to the battery.... almost. That's probably why calling it "Battery Power" seemed too misleading, so they abbreviated it ;-) It basically powers the whole system. Just my 2 cent ;-) Thanks for picking this up finally.
