The readings were relatively consistent (the same across multiple readings), though I know not absolutely accurate (adding up the four battery voltage measurements is consistently off by .1-.2% from measuring the chain all together in a single reading, and I have not tested the multimeter against a reference voltage to know how close it is). > Anyway it sounds like a tiny difference to me. To me too. It was the larger difference while charging that made me curious and thus seek the wisdom of the crowd regarding a physical model for that difference.

There might be just enough time for me to do that before mowing season, at which point I should be able to put the charging regulators on. ☺ Thanks everyone! _______________________________________________ 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)
