AGM Battery Charging THE PRIME DIRECTIVE
I have gotten several communications about AGM battery maintenance. Using solar voltaic charging. The big error I read is that the subject of total and complete recharging is not mentioned. And tha...

Well maybe I should try a third call to Magnum specifically on Absorb End - Amps setting, when a BMK-Meter is in the mix. Go with a 2 out of 3 answer:)!
As I do now believe after my 'Burned as I learned:)!' poor management of the previous battery bank - that Absorb End set to Amps, would provide the best Magnum method of assuring the battery bank is getting back to a 'Full Charged' condition.
And yes, the MS2812 is a 4 Stage vs 3 Stage, my comment was more generic as in nature. I should have just said a Multi Stage Charger for my comment about even with Smart Battery Chargers - manual involvement of battery management maybe prudent/required.
Will take another run at Magnum for Absorb End set to Amps:)!
(And again, not knocking the Tech Support. I had a list of 7-8 items I went thru with the Tech I talked with. Mostly trying to understand the IRV2 poster 757Driver's info on how the MS2812 executes once it has reached Full Charge display. (The needing to drop to a value below 12.7V, and then going into Float for only 4 hours.). We spent the bulk of the time talking over this area, maybe 5-7 minutes reviewing my settings and talking about Absorb End - Amps vs SOC vs Time was within this 5-7 minutes. As well as the description on why the BMK-Meter displayed Amp values would at times be simnifically different then would be seen on Line 2 when on the Inverter/Charge menu. I had run about 5 cycles of draining down out about 150-175Amp out of the new battery bank, using a 1500W heater to be the main draw. Over 50-60A differences in what the two displayed. (BMK-Meter displayed Amps are from the Shunt. The Inverter/Charger Line 2 display Amps were from the Inverter.)
Fun stuff this be for sure:)!
