Can you set the inverter to produce say 20 amps constant current until voltage rises to say 16 volts. How about 20 volts. Or 10 volts? A constant current producing device is graded by the voltage limit that the device is capable of producing.
The Magnum can be set for constant current from 20 - 990 ADC of course limited by charger capacity which in my case is 125 amps. It can be set to transition to constant voltage from 12-16V.
The Lifeline recovery section denotes a constant current of 5% of 24 rated capacity applied until cell V reaches 2.58, then held for 4 hours more. The Magnum could do this if manually monitored except for they say the cell may reach 3V which would be 18V and the Magnum can only do 16V.
There are many more details to the Magnum charge settings that are explained throughly here starting page 20:
