I have never done much battery work and I was wondering if using a
separate battery with a common ground to the HB has caused anyone any
problems during charging or any other situation. I have common grounded a
3v battery pack to the HB supply to drive motors. The power node(+ term)
is nicely decoupled through a PowerFET.
thx,
jm
