Magnum MS2812 'Absorb Done' settings
Hi All, I've my replacement X's 4 Lifeline L16's installed in the coach. Lifeline has been just top notch to work with during this adventure. And are doing sort of a post mortem on my old bank ...

I wanted to thank you all for your input on this question.
I did also get the following feedback from Don (757Driver) on IRV2:
"Smitty,
If you have DC loads that come directly from the batteries Magnum does not recommend using ending amps for terminating the charge. In order to use ending amps you would also have to set it up as a CC/CV charger and I think that you might better off with Bulk/Absorb/Float and set the Absorb time to 3.0 hours."
Which is similar to the feedback here too.
I think what throws me off about all of this. Is my first charge of the new Bank of batteries, installed on Saturday. (I first ran the oven and 1500W heater for about 20 mins to remove enough Amps to lower the batteries down to kick into at least Absorb mode.)
I had the Absorb End set to Time = 3 hours. And after about 10 mins of Shore Power and Charge starting, the Amps seemed to settle at about 92 Amps. I went back every 45 Mins to write down the Amps reflected, and at the end of 90 mins it was down to 18 Amps. 45 mins later, now at 2 hrs 15 mins - the ARC-50 reflected Float mode. So 3 hrs Absorb End Time - 2 hrs 15 mins = 45 Mins early termination of Absorb cycle? (THAT IS WHAT CONFUSED ME. And why I started thinking Absorb End of 4 Amps might be the better way to go...).
Fun, fun...
