After reading through the PDF on the galaxy site, I'm relatively convinced. I've implemented reflex charging on our charger, with the addition of a FET and resistor for the pulse discharge. I'm planning a field test, with individual systems deciding wether to use reflex or constant current charging based on a bit in the internal serial number. They already log charging parameters, and we have the SW to pull the data and report it over the net. Give me a few months in the field, with the end user blind testing, and I'll be convinced one way or the other. -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
