Sorry, omitted those obvious details.  I am happy for the equipment to =20
be not in use whilst charging.

It would be only be a benefit if the batteries could be charged =20
in-situ by a external DC source from a wall-wart (so realistically =20
around 5v to 12v).  i.e. no need to remove them or disconnect the pack =20
or I might as well use a simple off the shelf charger.
