 This is not fixed.  I setup a test on Friday and let it charge over the
 weekend. On Monday the batteries were still not charged.
 Reviewing the B2 schematic I can see nothing that would trickle charge the
 battery if the EC is not active.  I asked Dave Woodhouse if he knew
 anything about the trickle charge.  This prompted him to remember that the
 trickle charge did NOT make it into the B2 build.  So add that to your
 list of things that need to go into B3.
