What capacity do your cells have? The default of the charging algorithm is
1500 mAH. Remember that I don't load the settings yet. Maybe the discharge
curve is different, the capacity "measurement" can be no more than an
estimation.
Rockbox tries to determine the charge time and also uses a delta method to
stop charging, versus Archos does a "brute force" charging, I think.
