high rate charging on generator
Hi all, The batteries: 556 amp-hours of surplus acid AGM batteries 12 volt jars 105 lbs each. They are wired as two banks with balanced wiring. The depth of discharge: 12.1 volts under 425...

Hi Landy,
Output voltage so far as I am aware is set as a 'favorite' which allows me to change it. But the voltage was not at 14.5--I think it was only 12.9 during the event.
I doubt that the Magnum over heated in under one minute. I watched as the amperage flew up to 127 then announced 'fet overload' and shut down the charger.
I've only seen bulk charging once before--and that was with my old tired flooded batteries. They were charging at 125 amps.
I am using a custom setting for output voltage rather than the two agm choices Magnum is set up for. The reason I did that is because the float voltage was not 13.8.

If you can change the output voltage, you can change the charge output amps.
But you might have to keep twiddling voltage upwards to keep it close to the 125 max output.
I wonder if this is something that could be attenuated with more ventilation.
