Putting words in my keyboard again. I never said "few" millivolts. In the SI system of measurement, "millivolts" are less than a volt and more than 999 microvolts. I recon that describes the sag in most high-current EV batteries. (Sorry, my turn to be a pedant.) Anyway, this has been sorta fun, but I've got work to do. Play nice in the sandbox, now, kids! :::: What is truth? That old question has had so many expedient answers that you have to be careful where you ask it. When I ask it here at the foot of the mountain the answer is that truth is the way things are, not the way we shape them or contrive them or wish they were, but the way they are. -- Hal Borland :::: Jan Steinman, EcoReality Co-op :::: _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
