From the Magnum manual:

AFAIK The current part of that graph doesn't represent the normal charging amps going into a depleted battery. As mentioned in this thread, the amps should start high and decline until float.
But I guess the Magnum does something different in Bulk, where it increases its applied V to the final bulk voltage?
Odd that they call that phase "constant current" when the voltage and current is increasing in Bulk.
Really don't understand what's happening there.
The time scale on the chart is deceiving they seem to be exaggerating the ramp up time in bulk, my Magnum 3000 ramps up to max charge current very quickly and stays there in bulk until absorbs volts are reached then switches to absorb and current ramps down while voltage is held. The Magnum ARC remote manual has better charts and info on programming the charge profiles which are very customizable including CC/CV for Lithium.
Ah thanks. That makes a lot more sense.
So, ignore the bulk current part of the graph, most of bulk (except for a brief "soft-start") really is max constant current, as expected.
