Hi all, I'm needing some battery backup in my next project. I'm planning on using a 3v NiMH cell. I'm hoping on a simple trickle charge system. Do I need anything more complicated than a current limiting resistor? If not, what resistance do we assume the battery will have under charge? Forgive me if I'm looking at this incorrectly.... The Yausu battery web site suggests this is possible but doesn't give examples to explain the value of R required. Ben -- http://www.piclist.com hint: The PICList is archived three different ways.
