The slave board turn automatically OFF when there is no communication for more than 10 seconds. It's not a true OFF state but a deep sleep state, and the current consumption on the cell is a few ľA, thus much less than self-discharge of the cell. The slave board wake up automatically when it receives a request frame form the mother/master board.

And the mother/master board is completly OFF until ignition key is ON or charger is plugged.

No possible at my opinion, cost will be too high and wiring more complicated.
