This should be my last question in terms of batteries. Assuming that I have
nicads powering the HB, what effect would there be if, when the batteries were
getting low, I connected a fully charged battery pack (e.g. containing the nimh
cells) into the power jack ?. I imagine that the nimh pack should power the
board and charge the nicad pack slightly. Am I correct ?. I am now thinking of
using the nimh cells as either a backup power supply or as a supply for the
comms converter board (which has the overall effect of the above question) so
that the hb batteries should only be powering the hb when connecting the
converter to a laptop where there is no access to mains power.
Can someone confirm if my thoughts are viable ?.
Thanks

| you're almost right. if you plugged a nimh pack into the HB's charge jack, the external pack would charge the internal batteries. but it would not power the board significantly. this is because the HB's charge jack includes a current-limit resistor (...)
