Hmm, Hyperion must have changed the algorithm. My EOS7i does that 0v every minute thing only when charging NiMH in "auto" mode. Since the charger has no idea what capacity battery connected, it looks at how much the voltage falls when the charge current is removed. If the voltage falls just a little, it increases the charge current. If the voltage falls a lot, it reduces it. Larger capacity batteries will have less voltage change from charge to no-charge. It still uses delta peak for termination though.

But, when charging lipos or NiMH in a set mode, the charge current doesn't change unless I tell it to...
