You seem to be referring to item 8 of the B787-8 special conditions pertaining to lithium ion batteries:
(8) Any lithium ion battery installation whose function is required for safe operation of the airplane must incorporate a monitoring and warning feature that will provide an indication to the appropriate flight crewmembers whenever the state-of-charge of the batteries has fallen below levels considered acceptable for dispatch of the airplane.
Does that exclude the possibility that the main battery would be charging after takeoff?
