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

I've found that alkaline batteries work well. I used it to power motors too and they seem to work fine. I tested a flashlight bulb and found that it drew 0.79 A at the rated voltage. So alkaline, D-cells at least, can handle the current. ---...--- (...) (30 years ago, 3-Apr-97, to lugnet.robotics.handyboard)
