That gives roughly the same number as the 38.2V I got from the per-cell
voltage approach (I think the Battery University's number works out to
almost exactly 38V - but that is lower than what you get with the
per-cell voltage given by Trojan). My main concern is that setting it at
exactly the voltage for a fully charged pack would mean that it would take
a long time to charge, since it will take a long time to drop back down
below the cut-off after each 5 minute charging interval.
